Dear Wietse So i don't understand your smtpd_reject_unlisted_sender definition. I need your help to understand your last answer. "Request that the Postfix SMTP server rejects mail from unknown sender addresses, even when no explicit reject_unlisted_sender access restriction is specified. This can slow down an explosion of forged mail from worms or viruses. An address is always considered "known" when it matches a virtual(5) alias or a canonical(5) mapping." Has the definition say, i need to define a database virtual/canonical maps in order to let postfix "known" senders to set this feature working. Has for me the issue is that internet recipients are bogus not senders.
