SMTP issues - unable to connect : CentOS 6.5, Postfix, Dovecot, MySQL
Hi
I'm try to setup an email server on a CentOS system with Postfix, Dovecot and MySQL.
I'm following this article for an Ubuntu system:
https://library.linode.com/email/postfix/postfix2.9.6-dovecot2.0.19-mysql
I can connect to the server using both secure pop/imap but can't with SMTP. I have tried sending an email from root and it remains in the queue. I get the follow error:
connect to osiris.example.com[private/dovecot-lmtp]: No such file or directory

Reply 1Yeah - a few differences between Debian & RHEL based systems
Reply 2As you've discovered there are a few config differences between Ubuntu and CentOS. Apache config is one that also springs to mind.
FWIW these are the TKL forums anyway (which is a Debian based distro of pre-built/pre-configured software appliances - most with postfix pre-configured) so the chances of anyone here being able to help you with CentOS was probably slim anyway...
It seems this entry only in /etc/postfix/main.cf applies to Ubuntu/Debian systems.
With CentOS systems you'll need to specify the following:
You'll also need add this entry in the /etc/postfix/master.cf file:
dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${recipient}
