Hello list I'm aware of two ways to verify recipients when relaying mail to upstream Exchange servers:
- Export recipient addresses from AD and use that list as $relay_recipient_maps. - Use an LDAP query in $relay_recipient_maps. I seem to recall that there was a third option where Postfix would probe the nexthop before accepting the mail, but was unable to find it in the list archive. Can someone refresh my memory? Or did I mis-remember that? TIA Regards Ansgar Wiechers -- "Abstractions save us time working, but they don't save us time learning." --Joel Spolsky
