Virtual users and domains with postfix courier mysql etc

I followed following tutorial some months ago ( http://www.howtoforge.com/virtual-u...courier-mysql-and-squirrelmail-debian-squeeze ), but i do have an important update question :

Whenever i do apt-get update & apt-get upgrade and choose yes, the system gives errors when wanting to update postfix and postfix-mysql.

In the tutorial Step 3. it talks about patching postfix with the quota fix, which i did.

But since i am unable to install the normal updates for postfix, i was wondering what was the correct way now to update postfix + postfix-mysql and how to apply the quote patch ?

Regards,

 

You shouldn't update Postfix (unless you want to patch it again). Take a look at chapter 4 on http://www.howtoforge.com/a-short-introduction-to-apt-pinning-p2 to learn how to do it.

 

Thanks ! will give that a go
