When changing a bug (like adding a CC), the kde bugzilla sends out emails to other interested parties. Not only does it set the 'From' header field of those emails to the name and email-address of the person that changed the bug, but apparently also supplies this address as envelope-from, which causes immanuel.kde.org's postfix to send occuring bounces to the person that changed the bug.

see below for an example (@ and . removed from email addresses):

    for name=riderinvasion.no-ip.com type=AAAA: Host found but no data record

Please configure the kde bugzilla to not use a foreign email-address as envelope-from. It should also not use an users address as the 'From' header in autogenerated emails.

If this can not be configured, i will take this to upstream.
