No, that would be immensely stupid, especially if the email address
is not remote. Postfix probes follow the same path that ordinary
e
count).
If you have an address username@domain and you want to send mail to that
address (and Postfix sender verification works just like that - attempts to
send mail to the address, and if SMTP transaction is accepted, cancels the
attempt and backs out before DATA stage), and "domain" does
reject_unverified_sender permit_mynetworks
relayhost = [smtp.antispamcloud.com]:587
Since smtp.antispamcloud.com has a very strict sender verification
process we want to reject the same mails. Hence we enabled
reject_unverified_sender. It looks like our Postfix server accepts mail which
has a sender www
. I know the legitimate sender addresses for this domain
by reading from tables.
I receive spam from nonexist...@example.com. How do I turn on sender
verification address only for the domain I handle and block ONLY for
nonexistant local addresses?
smtpd_reject_unlisted_sender=yes or
domain by
reading from tables.
I receive spam from nonexist...@example.com. How do I turn on sender
verification address only for the domain I handle and block ONLY for

Let Postfix do the permit_mynetworks, permit_sasl_authenticated etc.
va
Is there a way for a policy server to validate senders using Postfix's built-in
authentication (like meeting permit_mynetworks and permit_sasl_authenticated)?
Or must the necessary checks be duplicated?
