Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Status changed to 'Confirmed' because the bug affects multiple users.

Also seeing this. Renumbered the exit status codes in postinst. Fails in #3 which is start/restart courier-mta. Error is "failed dependency".

[Matthias Wolf (matthias.wolf)]

Also seeing this.

The problem seems to be the submission assistant, as courier-msa fails with an ›invalid parameter‹ error.

I looked into the startup scripts and configuration files and compared to a running server, but found nothing relevant.

What can I provide to track that down? This issue has been open for 1½ years now!
