We have a mailserver running on Postfix.
Only authenticated users are allowed to send emails.
One client has a multifunction printer, which is configured to send scanned documents to an email recipient.
Unfortunately that printer is an older model and doesn't support smtp-auth.
I know I can use check_client_access to allow the static IP of this client for unauthenticated mail.
The following configuration would do that:
smtpd_sender_restrictions =
check_client_access hash:/etc/postfix/allow_relay,
permit_sasl_authenticated,
permit_mynetworks,
reject_non_fqdn_sender,
reject_unknown_sender_domain,
reject_unauth_pipelining
What I would like to do is to only accept unauthenticated email if the IP and the sender match with a list.
Just adding a check_sender_access to the sender restrictions would result in allowing Mail from the specified IP or the specified sender.
So how could I configure Postfix to combine those two, if possible at all?
Best Answer
By configuring a restriction class that checks the client IFF the sender matches $foo, or vice versa.
