[IMail Forum] smtp log question

[Avery Pierce]

Heres a couple of lines in my logs:   20030306 101018 127.0.0.1       SMTPD (245D013E) [int nat ip address] connect 63.144.247.13 port 2631 20030306 101019 127.0.0.1       SMTPD (245D013E) [63.144.247.13] EHLO fl-nked-ubr2-c5a-2.dad.adelphia.net   Its my understanding the first line tells me where the connection came from.  In this case its 63.144.247.13 port 2631.  Heres the problem 63.144.247.13 is camteq.net (ip of my domain).  Shouldnt the ip read 24.53.194.2 which is were I made the connection from.  Am I reading this wrong or is something not setup correctly.   Imail server sits behind a linux firewall doing nat and port forwarding.  I dont think it could be a nat problem because other services like IIS show the correct connecting ip address.  Any ideas?  Thanks in advance.
