Problem with Postfix+Dovecot+MySQL

Tue, 13 Apr 2010 21:16:06 +0200

I installed postfix with dovecot and mysql but I faced some problem...

First of all it seems like when I am starting the postfix process it's taking 20%wa ...

Than when i'm trying to send message from gmail to my mail box it seem to reach fast to the /var/spool/postfix/incoming/... but it's not coming to the defined mail dir in /home/vmail/domain/mailbox... Until I restart the postfix than it shows up there and it happens again and again, sometimes it reachs without restart but it takes quite long time. It's not problem with the server connection or speed because it arrives the spoll directory very fast so it might have somthing with the postfix process that stuck?

Another thing, when I try to send message to someone like gmail.com or other host it says relay host denied , how do I open all relay host? not just few I set manually.

Thanks very match!

Postfix virtual user transport - help!

Sun, 26 Jul 2009 21:32:50 +0200

Strange issue here, but I'm sure it is possible under Postfix.

I've been running some mail servers successfully for some time, but now want to tighten up some controls.

At present, my home machine accepts mail for a few of my domains, filters out local recipient addresses (drops them into local mailboxes) and anything else then hits transport to get forwarded upstream to another mail server. That way, my mails stay local, mails for my mates get forwarded (transport) to our public mail server (and drops into their POP3 mailboxes) and mails with unmatched recipients are bounced by the upstream server.

Now I want to change things slightly. I want to have a whitelist of valid addresses (like local_recipients) on the home server, and if incoming mails don't match these then immediately reject them. Unfortunately, postfix only sees recipients in my virtual.db and not transport.db, so I get my mails but my mates' are rejected with "User unknown in local recipient table".

The only workaround I've managed is to flick "local_recipient_maps = " so that postfix won't bounce recipients unlisted in virtual.db.

So.. anyone shed any light here?

Help! Certain clients don't receive my emails? :(

Mon, 09 Feb 2009 09:44:22 +0100

Hello all....I use an email blasting software for my clients and newsletter and this is what happened: I was at my mother's house and accidentally used the wrong server (I do my marketing on a diff. smtp server) and after I did that when I sent emails to my mother's email address (with the isp she is with, cox) she would not receive my emails. I called my domain company godaddy and they said there was no problem on their end as I did tests and my emails went through. I called my mom's isp service and they said there was nothing wrong but to email this email address for "blocked" accounts and they never responded but the weird thing is when I send my mother email's, they go through if I send it from the "online backend" of godaddy rather through my MS Outlook. To make things worse...one of my clients who has TimeWarner doesn't receive my emails either!

The weird thing is, when the email goes through it shows as it has been sent and I receive no bounced back message! So far I know of only cox and timewarner but I don't know what to do? I looked at all the blacklists that I could online and it seems that our domain is not blocked (from what I know) and this issue has happened with multiple user emails (with the same domain) as for example my gf's outlook account on her computer does the same thing! As I mentioned, it works if I log-in on the backend of godaddy but not through the outlook. I don't know if there is a port being blocked or something that they may have sent somehow to my outlook so they recognize it's me? I know it sounds crazy and I am pretty computer savvy and I don't know what else to do!

Thanks again everyone...I use Outlook 2007 and I know my smtp settings are correct so any input or advice would be GREATLY appreciated. I have done some online research and tried to figure out what the basic steps may be but I really have come to a deadend. This has been happening for about 2-3 weeks now. Thanks again....and hope everyone had a great weekend!

Emails not being sent to Hotmail from site

Fri, 09 May 2008 11:07:27 +0200

I have a strange problem. I have a script that sends out emails and it used to work fine to all email addresses, but I recently moved the site to a dedicated server and now it won't send out emails to any Hotmail accounts. None of the Hotmail accounts have got spam filters on and they all used to get email from the site. All of the script is the same as I say the only difference is the site is now on a dedicated server. Both the old and new servers are RedHat Linux using php5. I went into the php.ini file and all I found for SMTP is:

Quote:[mail function]; For Win32 only.

SMTP = localhost

smtp_port = 25

; For Win32 only.

;sendmail_from = me@example.com

; For Unix only. You may supply arguments as well (default: "sendmail -t -i").

sendmail_path = /usr/sbin/sendmail -t -i

The send_mail() function is:

Code:

function send_mail($to, $from, $subject, $message)

{

global $g;

if (isset($g['options']['mail_html']) and $g['options']['mail_html'] == "Y") $ct = "text/html";

else $ct = "text/plain";

if (isset($g['options']['mail_utf8']) and $g['options']['mail_utf8'] == "Y") {

    $headers = "From: " . $from . "\n";

    $headers .= "Content-Type: " . $ct . "; charset=utf-8;\n";

    $headers .= "Reply-To: " . $from . ";\n";

    $headers .= "Return-Path: " . $from . ";\n";

} else {

    $headers = "From: " . $from . "\n";

    $headers .= "Content-Type: " . $ct . ";\n";

    $headers .= "Reply-To: " . $from . ";\n";

    $headers .= "Return-Path: " . $from . ";\n";        

}

if (isset($g['options']['mail_utf8_subject']) and $g['options']['mail_utf8_subject'] == "Y") $subject = '=?UTF-8?B?'.base64_encode(trim(preg_replace('#[\n\r]+#s', '', $subject)))."?=\n";

mail($to, $subject, $message, $headers);

}

but that all works fine. It's just that the emails aren't being sent to Hotmail addresses.

I read something about port 25 being blocked and that's why Hotmail addresses aren't receiving the emails, but I've just checked and port 25 is definitely not blocked:

Virtual IIS SMTP Server + Iptables

Tue, 29 Apr 2008 16:36:05 +0200

Hi Everyone, first post here!

I'd like some help with that situation:

I have a CentOS server running up (Let's say IP: 10.00.00.01)

Which emulate a Windows 2003 Server which has 2 Network Adapter. Let's say the IP of the IIS SMTP Server is 10.00.00.02.

Right now, on the 10.00.00.02 server that is a web application running that must send e-mail. The email are being created (they are found in c:\inetpub\mailroot\queue). I'm pretty sure that it's the firewall of the centos that are blocking the mail (iptables).

After a lots of unsuccesful attempt on iptables i've decided to remove everything that is being related to smtp and port 25 / 110 and ask for help!

Anyone encountered the same situation and can give me the basis of iptables to allow the mail to be sent?

Thanks a lot!

Postfix bouncing

Setting Up Postfix On Debian Etch

Fri, 23 Mar 2007 15:20:36 +0100

Ive read lots of 'how-tos' on how to do this but none of them worked on there own, I managed to get it working by merging bits of information together and heres how i got it working on Debian Etch, this might work on Debian Sarge too.

TARGET MACHINE

apt-get install postfix-tls sasl2-bin libsasl2 libsasl2-modules << stuff required for postfix

apt-get install popa3d << this is the pop daemon for downloading mail from server

edit /etc/default/saslauthd and make sure these lines say:

START=yes

MECHANISMS="pam"

edit /etc/postfix/sasl/smtpd.conf if this file doesnt exist create it!

pwcheck_method: saslauthd

edit /etc/postfix/main.cf (remove old config, copy and paste everything here but change ******)

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)

biff = no

append_dot_mydomain = no

myhostname = ****** # make sure this is resolvable (ie use yourmail.net)

mydomain = ****** # make sure this is resolvable, i got mine working using same as above.

myorigin = $mydomain

inet_interfaces = all

mydestination = $mydomain, localhost.$mydomain, localhost

mynetworks = 127.0.0.0/8, *.*.*.*/* # change this to local address + subnet so emails can be relayed out your box

smtpd_sasl_auth_enable = yes

smtpd_sasl_security_options = noanonymous

smtpd_sasl_local_domain = ****** # i used same as 'mydomain' above

broken_sasl_auth_clients = yes

smtpd_sender_restrictions = reject_unknown_sender_domain, reject_unverified_sender

smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination

postfix does a chroot so it can’t communicate with saslauthd. heres how to get round it:

rm -r /var/run/saslauthd/

mkdir -p /var/spool/postfix/var/run/saslauthd

ln -s /var/spool/postfix/var/run/saslauthd /var/run

chgrp sasl /var/spool/postfix/var/run/saslauthd

adduser postfix sasl

add a test user (remember to remove after)

useradd test

passwd testpass

edit /etc/passwd (so test cannot log in via ssh)

test:x:1001:1001::/home/test:/bin/false <

start postfix + saslauthd services

/etc/init.d/postfix reload

/etc/init.d/saslauthd start

TEST POSTFIX CONNECTION WITH TELNET ON REMOTE MACHINE

We need perl to generate the string for the SASL telnet authentication

perl -MMIME::Base64 -e 'print encode_base64("testtesttestpass");' << change test / testpass accordingly

dGVzdAB0ZXN0AHRlc3RwYXNz << this will be used for authentication on telnet

telnet postfixmachineip 25

type 'ehlo localhost'

you should see something like this:

250-randallbum.net

250-PIPELINING

250-SIZE 10240000

250-VRFY

250-ETRN

250-AUTH LOGIN PLAIN DIGEST-MD5 NTLM CRAM-MD5

250-AUTH=LOGIN PLAIN DIGEST-MD5 NTLM CRAM-MD5

250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN

now enter these commands and see if you get same response:

AUTH PLAIN dGVzdAB0ZXN0AHRlc3RwYXNz

235 2.0.0 Authentication successful

MAIL FROM:

250 2.1.0 Ok

RCPT TO:

250 2.1.5 Ok

DATA

354 End data with .

This is a test email message, this better f****** work!

. << end message with '.'

250 2.0.0 Ok: queued as F11F234271

QUIT

POPA3D opens POP port 110 on the post fix server and also authenticates with users on the system the same way as Postfix has been setup to do. You could test this by sending a test email to the test user using the above method then setup a client like 'Evolution' to receive POP mail by putting in these details under 'Receiving Mail'

Server: postfixmachineip

Username: test

Now when you check for new mail it will ask for a password so use 'testpass' if you used method used here.

And if all went well, you should of received the test email.

Now you can do the same and put in the SMTP details for 'Sending Email'

Dont forget to remove user 'test' and put in some real users with strong passwords and disable ssh access if needs be.

Mail server - setup virtual mail boxes

Sat, 10 Feb 2007 16:27:18 +0100

Hi folks,

AMD Athlon54 X2 512Kx2 socket AM2 3800

slamd64-11.0

Just completed installing the captioned OS with everything installed except GAME. This is an experiment. slamd64 is now running on the box.

I'm going to setup virtual mail boxes on this server, allowing my friends using the mail server sending and receiving mails. Please advise;

1) how to check whether sendmail is running and configured properly.

2) how to setup virtual mail boxes. Where can I find relevant tutorial.

TIA

Setting Up Sendmail

Postfix+Dovecot+mysql

Fri, 29 Sep 2006 19:50:55 +0200

Ok.. so recently I moved photoblog.com off a old crappy server that had cpanel on a nice server that doesn't run cpanel. So I needed a system for virtual hosting for emails mainly. I've setup postfix+mysql+courier before and courier can be a GIANT bitch. So I looked into dovecot and was very happy.

So lets start off.. lets download PostfixAdmin. As of writting this you can use the following since its the current version

Code:
wget http://high5.net/postfixadmin/download.php?file=postfixadmin-2.1.0.tgz

tar zxfv download.php?file=postfixadmin-2.1.0.tgz

cd postfixadmin-2.1.0

ok my wget saved it as download.php.... your results may vary

Ok now once its installed we want to import the basic DB layout into mysql. Edit the file if you want to change the user/pass.. but you will have to change it in other files below.. so just take note if you edit it.

Code:
mysql -u root < DATABASE_MYSQL.TXT

So that command is the default install of mysql that you didn't set a root password on.. use the -p flag if you did

ok now that the layout is there lets get postfix and dovecot installed. Now the default version of postfix that ships with fedora/centos DOES NOT HAVE MYSQL FUNCTIONALITY BUILT IN. So this will be for centos or rhel you have to install the centos Plus version of it.

Code:
wget http://mirror.trouble-free.net/centos/4/centosplus/i386/RPMS/postfix-2.1.5-4.2.RHEL4.mysql.centos4.i386.rpm

rpm -ivh postfix-2.1.5-4.2.RHEL4.mysql.centos4.i386.rpm

yum -y install dovecot

Ok great all the needed stuff is installed. So lets add a vmail user to the system

Code:
groupadd -g 901 vmail

useradd -u 901 -g 901 vmail

Then you want to edit /etc/postfix/main.cf and add this to the bottom. Take a note of /vmail change that to the location you want to store all your email in.

Code:
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf

virtual_gid_maps = static:901

virtual_mailbox_base = /vmail

virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf

virtual_mailbox_limit = 51200000

virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf

virtual_minimum_uid = 901

virtual_transport = virtual

virtual_uid_maps = static:901

ok save the file and create a new file in /etc/postfix/mysql_virtual_alias_maps.cf and add the following

Code:
user = postfix

password = postfix

hosts = localhost

dbname = postfix

table = alias

select_field = goto

where_field = address

ok save the file and create a new file in /etc/postfix/mysql_virtual_domains_maps.cf and add the following

Code:
user = postfix

password = postfix

hosts = localhost

dbname = postfix

table = domain

select_field = domain

where_field = domain

#additional_conditions = and backupmx = '0' and active = '1'

ok save the file and create a new file in /etc/postfix/mysql_virtual_mailbox_maps.cf and add the following

Code:
user = postfix

password = postfix

hosts = localhost

dbname = postfix

table = mailbox

select_field = maildir

where_field = username

#additional_conditions = and active = '1'

ok save the file and create a new file in /etc/postfix/mysql_virtual_mailbox_limit_maps.cf and add the following

Code:
user = postfix

password = postfix

hosts = localhost

dbname = postfix

table = mailbox

select_field = quota

where_field = username

#additional_conditions = and active = '1'

ok save the file and create a new file in /etc/postfix/mysql_relay_domains_maps.cf and add the following

Code:
user = postfix

password = postfix

hosts = localhost

dbname = postfix

table = domain

select_field = domain

where_field = domain

additional_conditions = and backupmx = '1'

now save that and lets chown them

Code:
chmod 640 /etc/postfix/mysql_*

chgrp postfix /etc/postfix/mysql_*

Now lets create the /vmail dir and give it the correct permissions

Code:
mkdir /vmail

chmod 771 /vmail

chown vmail:vmail /vmail

now lets restart or start postfix in this case we will start it

Code:
service postfix start

If you have sendmail on the machine already a nice little rpm to download is system-switch-mail once download run the command by the same name.. select postfix and it'll be running

Now go back to the place you untared postfixadmin and point our browser to that location like

[/url][url=http://jyiscool.com/postfixadmin/setup.php]http://jyiscool.com/postfixadmin/setup.php

Make sure you pass all points.. then you want to remove the setup.php file

Ok now in the postfixadmin dir do this

Code:
cd admin

You need to setup the .htaccess file. So edit .htaccess in that dir and it will look something like this

Code:
AuthUserFile /some/dir/to/go/mail/admin/.htpasswd

AuthGroupFile /dev/null

AuthName "Postfix Admin"

AuthType Basic

require valid-user

You want to change AuthUserFile to the path where that .htpasswd file is that you just put your postfixadmin app.

Once thats installed delete the file and we will create a new one since we don't want to use the same admin user that is in there by default

Code:
rm -rf .htpasswd

htpasswd -c .htpasswd username

Now edit the config.inc.php file

Code:
cd ..

mv config.inc.php-dist config.inc.php

Basically you just have to change some defaults to suit your needs.. From there you should be able to access the admin error by entering the user/pass you just made and create a new domain and create some new users..

Once you have done that you should be able to use the local mail command to send off a test email to make sure its in the /vmail dir

Code:
echo testing 1 2 3 | mail -s test user@jyiscool.com

if you see a /vmail/user@jyiscool.com directory then it worked.. yayaya

Now I like setting up new services like I like my women.. easy

So create a new file called /etc/dovecot-mysql.conf with the following contents

Code:
db_host = 127.0.0.1

db_port = 3306

db = postfix

db_user = postfix

db_passwd = postfix

db_client_flags = 0

default_pass_scheme = PLAIN

password_query = SELECT password FROM mailbox WHERE username = '%u'

user_query = SELECT maildir, 901 AS uid, 901 AS gid FROM mailbox WHERE username = '%u'

Save that and edit the /etc/dovecot.conf file and add the following at the bottom

Code:
auth_userdb = mysql /etc/dovecot-mysql.conf

auth_passdb = mysql /etc/dovecot-mysql.conf

first_valid_uid = 501

default_mail_env = maildir:/vmail/%u

i also turned off ssl.. I might enable it in the future and append to this howto.. but for now in my dovecot.conf there is ssl_disable = yes

Now start dovecot

Code:
service dovecot start

You should not be able to grab that email you just sent that user via imap/pop3

Now make sure both get loaded on boot

Code:
chkconfig dovecot on

chkconfig postfix on

Now I am pretty drunk now while doing this so there could be many errors.. deal with it

trouble with qmail ldap

Mon, 01 Aug 2005 02:41:49 +0200

so i got ldap working and it was onto qmail + ldap via this how-to:

[/url][url=http://www.zcentric.com/wiki/tiki-index.ph...8b0db05031b920f]http://www.zcentric.com/wiki/tiki-index.ph...8b0db05031b920f

everything was goin great till the end. when i got to this part:

Code:
Now lets test out to see if qmail-ldap sees that new user

/var/qmail/bin/qmail-ldaplookup -m testemail@domain.com

You should get something that looks like your email.ldif file

i instead got the following:

Code:
[root@undergroundinfection /var/qmail/control] /var/qmail/bin/qmail-ldaplookup -m j@undergroundinfection.net

qmail-ldaplookup: fatal: qldap_bind: ldap server down or unreachable

thoughts, ideas, possibilities, files needed to help me? I'm stumped and my head feels fried.
