Well, I'm not fully correct here. You can filter on client addresses with check_client_access rule, and on sender addresses with check_sender_access. You can use both in smtpd_sender restrictiona, although I generally use check_client_access in smtpd_client_restrictions, and check_sender_access in smtpd_sender_restrictions. -- Regards, Jaroslaw Rafa [email protected] -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
