Postfix broke after update, please help!

Brandon.Wamboldt · 12-05-2009, 09:28 PM

I am running CentOS and ran yum's update service today. Postfix is now broken. I don't see anything in any log files and have no clue what to do. What should I do?

After this I am switching to qmail or something, postfix is always breaking

Postfix is setup to use Courier Imap for MySQL authentication (I think)

Also when running telnet localhost 25 nothing shows up

Apparently my system logger was misconfigured, after fixing the issue I found this in my maillog

Remember, postfix worked fine before the update. The important line is fatal: unsupported dictionary type: mysql

qmail will not make you a better sysadmin. Where did you get the previous
version of postfix? The one that's in the base/updates repo doesn't have mysql support.
The one in centosplus does. If that's what you used previously, you can delete what you
have and do a

Code:

yum --disablerepo=* --enablerepo=centosplus install postfix

Prevent this problem from happening again by editing /etc/yum.repos.d/CentOS-Base.repo:

Code:

[base]
name=CentOS-$releasever - Base
...
exclude=postfix*

[updates]
name=CentOS-$releasever - Updates
...
exclude=postfix*

Start with removing write permission from group and other from all the files mentioned near "group or other writable".
