Bug Description

Binary package hint: update-manager

Last night I upgraded from 5.10 to 6.06, using Synaptic. During the process it was reported that the upgrade had failed for postfix, mailx and mantis and on each occasion I was asked to report a bug for this.
So here we go.
Unfortunately I will not be able to attach the upgrade logfiles, as the upgrade has also caused another serious problem: all desktop applications and all terminal windows started from Gnome now insist on directing their traffic through a (non-existant) proxy at local IP 192.168.100.2. In consequence, Firefox is not operational and I submitting this bug from my Windows desktop (running on a separate PC with no access to the Linux filesystem).
I am not a Linux fundi, so no idea how I could get these files across (if anyone can help, I will gladly submit them here).

Here is what causes the error:

Running newaliases
 * Stopping Postfix Mail Transport Agent postfix [ ok ]
 * Starting Postfix Mail Transport Agent postfix
 * Starting Postfix Mail Transport Agent postfix postfix/postfix-script: fatal: the Postfix mail system is already running
                                                                         [fail]
invoke-rc.d: initscript postfix, action "restart" failed.
dpkg: error processing postfix (--configure):
 subprocess post-installation script returned error exit status 1

This is a bug in postfix, reassigning.

Cheers,
