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.
