Sender address rewriting
-----BEGIN PGP SIGNED MESSAGE-----
We need to rewrite sender adresses from the form:
to the following form:
because the main SMTP server has a list of valid sender adresses in that form.
There was no problem with sending mail from users, as they have their mail
clients configured to use email@example.com. But the problem
appeared when we started to use vacation. The vacation replies used the form
firstname.lastname@example.org, and such mail bounced back to postmaster.
We use fqdnaliases to deliver mail, and I foud that userdb can rewrite the
- From header, but it was not sufficent. The upstream SMTP server still sees
the "bad" sender adress (perhaps in SMTP command MAIL FROM ...) and refuses
to deliver the vacation replies.
Any help & hints will be appreciated.
Best regards and thanks in advance
