Hello,
If I understood correctly, I need to have a "list" containing the "jailed"
user1@domain_AB. Let's call it restricted_senders as in the pf docs.
---8<---
#
user1@domain_AB local_only
---8<---
I have added it in my main.cf (I add smtpd_client_restrictions for
completeness, perhaps there is the issue in the combined setup?):
---8<---
But testing it, it doesn't work. Any helping hand here?
Check these conditions:
1. the smtpd_client_restrictions and smtpd_recipient_restrictions are often overridden in master.cf
for "submission" and "smtps (submissions)" services
Yes, for submission it is indeed in master.cf. Adding any restrictions like
previously mentioned breaks smtpd there due to not expected command line
parameter.
2. If the sender is in your $mynetworks, the
"check_sender_access btree:$meta_directory/restricted_senders"
is skipped because the first rule "permit_mynetworks" returns.
Correct, but not in this case. mynetworks are only my set of mail servers.
I found the solution by using in main.cf the
smtpd_relay_restrictions = permit_mynetworks,
check_sender_access
btree:$meta_directory/restricted_senders,
permit_sasl_authenticated,
reject_unauth_destination
directive. Works now.
Thanks for pointers and thoughts!
Florian
