Description
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 scripts-vhosts.mit.edu.

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?
