Postfix does not filter on headers. That's what milters can do. smtpd_sender_restrictions filters on sender address taken from *SMTP transaction* (MAIL FROM: command), not from headers. > I'd prefer to dispose of > xxx.goggleusercontent.com in one go, rather than a long list of CIDR > blocks. My table referenced in smtpd_client_restrictions contains bc.googleusercontent.com REJECT and it works well for rejecting mail from all *.bc.googleusercontent.com clients. -- 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]
