Disable mail to *

Reported by: andersk Owned by:
Priority: major Milestone:
Component: mail Keywords:


Many sendmail installations, including MIT’s, canonicalize eviluser@… to eviluser@…, which currently works like eviluser@…. People shouldn’t be able to get an email address at a domain that isn’t theirs without permission, so we should disable mail received at

This canonicalization is done by the remote server, not the receiving MTA, right? (So "patch postfix to remove this behavior" is not an option.)

As I recall, there were some sort of backwards-compatibility concerns about doing this. Does anybody remember specifics?
