By the way: does anybody know of a tool ready to use with Postfix, that does exactly this and only this, ie. allows to define sender/recipient pairs that are (with "default deny") or aren't (with "default allow") allowed to send mail to each other? I know this can be done using eg. MIMEDefang and writing appropriate filter function for it, but this is like using a cannon to shoot down a fly. Something as simple as check_recipient_access, but where you can use a lookup table containing both sender and recipient addressses, would be an ideal solution. -- 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."
