Peering and relaying are essentially unrelated, or, in some configurations, mutually exclusive. A peer group is designed to share the same recipient domain across multiple physical servers for incoming mail. SMTP sending to other domains should occur through a different logical network, that is, you should not attempt to use incoming peering and outgoing smart hosting on the same network. Smart hosting creates a hierarchy, while peers are theoretically non-hierarchical. On the other hand, peers can be used as independent outbound relays by their authenticated users; or, in a more ideal, scaleable setup, your mailbox servers are never used as the triage point (mailhub) for local-vs.-remote mail, as a farm of non-mailbox MTAs are used for this function. You say you have established a single IP address to allow relays from; does this mean that you have separate outgoing MTAs, but are pooling outgoing traffic through one of your peers before sending to the outbound farm? This is very unclear...don't see where a server farm and a single IP are coinciding. Give us a more complete description of the network--include IPs, peer config on each box, relay perms on each box. There are too many variables for us to guess at. -Sandy To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
