Hi all. I've read a lot about how to get postfix to implement sender address verification (S.A.V.), but I have the opposite problem: an MTA (running postfix) that is sending me mail has broken S.A.V., and my local MTA is configured to drop all email that does not verify properly. So, I'm basically getting no mail from this remote server, with no warning that I'm missing anything.
The remote MTA is sending mail from a bugtracker account and so they've configured their postfix to drop all incoming email to that address... but this breaks S.A.V. as well because it doesn't make a distinction between mail with an empty sender (S.A.V.) and mail with a non-empty sender (normal mail). I would like to solve this at the remote MTA (since it affects other people getting email from this bugtracker) rather than trying to convince my local MTA admins to add this remote to some kind of S.A.V. whitelist. I've discussed the issue and the remote MTA admins aren't sure how to do this in a simple way. I don't know much abut postfix admin (the last MTA I messed with was exim, but even that was years ago). There's probably documentation on it that I just can't find, because all my searches show info going the other way (how to handle it when your local MTA is postfix and you want to implement sender address verification there). Basically, what's a simple way to configure postfix ignore incoming mail to a given address, while still properly handling server address verification to that address? Thanks for any tips or pointers to docs, etc.!
