I'm running Cyrus/Postfix + Amavis/SpamAssassin
When spam comes in addressed to mailboxes which don't exist,
Postfix is generating Undelivered Mail Returned to Sender messages - often of
which these just build up because the from/reply-to address is
fake.
Is there anything I can do about this? Is this a setting
of Postfix or Amavis?
Thanks
David Hearn
