Upgrade switched me to qmail, I want to switch back to postfix

[SlobodanG]

Hi,

Please help me get back postfix.

I have upgraded Plesk from 9.5 to 9.5.2, and it switched from postfix to qmail, somehow leaving both packages installed.

First I have tried to switch back by using

/usr/local/psa/admin/sbin/autoinstaller --select-release-current --install-component postfix

as mentioned here: http://kb.parallels.com/en/5801

and that gave me:

Detecting installed product components.
You already have the latest version of product(s) and all selected components
installed. Installation will not continue.

I have also tried removing postfix in order to get it back with autoinstaller by issuing rpm -e --nodeps postfix-2.3.3-2.1.el5_2, but even after that I'm getting same message that I already have postfix installed.

At the end, I have tried to do update in Plesk to next version 9.5.3, but autoinstaller update fails telling me this:

The requested package "psa" could not be installed.

if you run the auto installer manually you should be able to select postfix

you can also remove it by just specifying the package name

rpm -e postfix --nodeps

or

rpm -e `rpm -qa postfix\*` --nodeps

I did so, but autoinstaller kept telling me that package is up to date (?!)

now, I have upgraded plesk to 9.5.4 and I'll stay on qmail for time being.
