Hi,
I have configured my postfix with the reject_sender_login_mismatch
option in the smtpd_sender_restrictions.
With this configuration, when a ussage wants to send an email with an
unauthorized sender it gets a reject message like:
553 5.7.1 : Sender address rejected: not owned by user

email with an attachment, and this email could be forwarded to another
recipients. Anyway to store it only once?
No way. Attachment is a part of a message body. Deduplicat
