There is no need for SASL authentication on port 25, which is used to receive mail. So turn off SASL auth on this port completely. Allow SASL authentication only on submission ports (465 and 587), then you can firewall IP in question on ports while keeping port 25 open. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "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 -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
