Apt-get upgrade and Virtual Users + Domains With Postfix, Courier + MySQL

[triak]

Hi,
We have been succesfully running our mailserver based on the Virtual Users + Domains With Postfix, Courier + MySQL (+SMTP-AUTH, SpamA, ClamAV) howto. Im about to upgrade our system. Is there anything special I should know about the procedure? eg. Could apt-get upgrade mess up some configuration files? For example the quota system patched into postfix.
It's a production server so i would not like to mess it up :=)
Can I just run the command and expect everyting will work after the update?

You cannot update Postfix because you will then lose the Postfix quota feature. To circumvent this, you can use apt-pinning: http://www.howtoforge.com/forums/sho...ht=apt-pinning

Hi,
I guess this thread is seeking the same knowledge with the one I started at http://www.howtoforge.com/forums/showthread.php?t=8610. I guess I should have used the search feature

Anyway, what I want to ask is; "Is Postfix the only component that needs to be pinned?" Is that what I should get from your reply, Falko? Cause, I believe that Amavis and SpamAssassin are the most common components that needs regular updates.

Yes, because the standard Postfix package doesn't have the quota patch.

Would this be an issue if the quota option is not being used?

Not if you don't need it.
