Incoming Relay and how messages are processed.

Hello, I have just configured Incoming Relays, it seems to work fine.
I finds the original sender IP and it assigns an SBRS score.
But, I just can't find why messages are processed according the outgoing policy.

Tue Oct 7 13:37:42 2008 Info: New SMTP ICID 5316 interface mail_IN (192.168.X.X) address 192.168.Y.X reverse dns host unknown verified no

Tue Oct 7 13:37:47 2008 Info: Message done DCID 7098 MID 8040 to RID [0]

Because it's processed like outgoing mail, ALL SPAM passes through the Ironport.

You'll probably want to remove the connection ip to a non RELAYLIST sendergroup.

From the sample provided, this entry:

Tue Oct 7 13:37:42 2008 Info: ICID 5316 RELAY SG RELAYLIST match 192.168.Y.X SBRS rfc1918

indicates the connecting IP is put on the relaylist, probably due to the 192.168.*.* subnet. Put this on a non RELAYLIST and then use the "incoming relay" feature to find the prior to the relay.

Then, use this article below to enforce the SBRS. You can see the SBRS of the hop before the relay has a low SBRS score.

Thank you, that worked.
