Hello,
We are using the SRS mechanism to avoid problem with the SPF when we forward emails to external servers. We have followed the documentation from postsrsd, in main.cf : sender_canonical_maps = proxy:tcp:127.0.0.1:10001 sender_canonical_classes = envelope_sender recipient_canonical_maps = proxy:tcp:127.0.0.1:10002 recipient_canonical_classes = envelope_recipient but with that method, the addresses are rewritten when postfix receives the mail (cleanup) and it's more difficult to deal with : exceptions in MailScanner for exemple, logging... It would be better if the envelope sender address was rewritten at the qmgr step but we don't find a way to do this, the smtp_generic_maps will rewrite both the envelope and the header address which should not be rewritten. Is it possible ? How ? Thanks -- Pascal
