Comment 1 for bug 1323704

Thank you for your report.

It looks like you have the mail-stack-delivery package installed, which is designed to alter postfix's configuration as declared in the package description: "This package modifies postfix's configuration to integrate with dovecot".

If you do not want to have your postfix configuration automatically managed, then why do you have mail-stack-delivery installed?

Marking this bug as Invalid, as I think the behaviour you describe is by design. If this is not correct, please explain and then change the bug status back to New. Thanks!
