Hi all,
I have set up some new rules in smtpd_recipient_restrictions (see below)
on my test machine. They don't work exactly as I expected. Is there a
way to log the output of each lookup performed? For example, in my
configuration I see some logging from the SPF policy checker, but I have
no clue what the result of the sender_access, client_access or RBLs is.
I can use postmap -q to get some results, but that's a bit cumbersome.
I added a mail.debug rule to syslog, but I don't see any more info than
what is already logged using mail.info.
smtpd_recipient_restrictions = reject_unauth_pipelining,
reject_non_fqdn_recipient,
reject_unknown_recipient_domain,
permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination,
warn_if_reject check_sender_access hash:/etc/postfix/sender_access,
warn_if_reject check_client_access hash:/etc/postfix/client_access,
warn_if_reject check_policy_service unix:private/policy-spf,
warn_if_reject reject_rbl_client relays.ordb.org,
warn_if_reject reject_rbl_client sbl.spamhaus.org,
permit
Second question: I'm currently using check_sender_access to block email
coming from non-existing user addresses at my domain. However, this only
checks the MAIL FROM address. Is it also possible to create a rule which
checks the From: header. (presumably such check should occur in
smtpd_data_restrictions or smtpd_end_of_data_restrictions?)
Regards,
Freek
