Hi,
I noticed that the address rewriting that postfix is doing seems to
rewriting invalid mailboxes as valid ones.
I noticed this while writing an automated test around a milter I have
which does a few privacy-alias-friendly things, like allowing you to
send messages with a From field that matches an alias you own (but
preventing you from sending a From field that does not match any owned
aliases), or re-writing the envelope-from in the case that your MUA
didn't bother to match your envelope-from to your From field.
What I noticed is that this invalid mailbox:
Sender: A <1...@splintermail.com
Is being sent to my milter as:
"A <1"@splintermail.com
The first form was invalid, but the second form is valid, which seems
like undesired behavior. Even if you were going to guess at the correct
address from the first form, the second form is a pretty poor guess.
Is there a way to disable this rewriting, or to better detect invalid
addresses so as to not rewrite them as valid addresses?
