postfix--qmail--postfix back and forth updates

[Michael neese]

I have postfix running in my plesk 9.2.3...today i ran :

yum --disableexcludes=all upgrade

Just in case there was something i was missing...

The upgrade was qmail...so i installed this as an upgrade...it went ok and things still worked in the email system..

Then later today i ran

yum update

...there was another update

psa-mail-pc-driver

So, i figured it was something to update on the qmail install...

Not at all! It totally shut down my mail system, removed qmail then reinstalled Postfix as my MTA!!!

What is this all about?

Postfix to qmail back to postfix?????Haven't checked yet , but I hope the damn thing still works..

Explain this freakish situation to me...I am really worried about the stability of this whole plesk upgrading and updating process.

Why you use yum instead Plesk autoinstaller for updating? You can switch MTA with autoinstaller.

/usr/local/psa/admin/sbin/autoinstaller

Yeah thats an RPM bug on the psa-mail-* packages, they always treat each other as an upgrade (havent dug into this far, but I my guess is because they're using an Obsoletes tag). So what you need to do is add an exclude= to the plesk.repo on one psa-mail driver or the other. By default I had set the atomic installer to create an exclude on the qmail one, with the intent of adding query in the atomic installer to set which one you wanted a preference for.

When you're running it with --disableexcludes=all its ignoring the excludes, which isn't always a bad thing. Just this time its creating this condition for you.
