I did have to resolve disaster: smtp (both clear text and SSL + sasl auth)
got broken. It turned out to be postfix package that came with CentOS 5.11
. I do not know details yet: with disaster you first make things work,
then figure out what happened and what is to blame. My temporary fix was
quick (it was troubleshooting that took an hour or so): I rolled back
postfix package:
rpm -Uvh --oldpackage
http://bay.uchicago.edu/centos/5.10/os/x86_64/CentOS/postfix-2.3.3-6.el5.x86_64.rpm
You may want to replace my mirror address bay.uchicago.edu with your
favorite mirror (and may change to 32 bit location if your box is 32 bit).
After that is done do
/etc/rc.d/init.d/postfix restart
And yes, I do feel shame for not testing update before installing it...
Note: you may go into details of how to really fix that (which I hadn't
chance to do for my servers), this dirty fix will just let you get out of
disaster quickly.
