Really strange as it looks like our exchange server is sending out thru
that ip as well.

This is worrying me... I don't remember this being like this... could
this have changed with sp1?

Interesting question....one I've never poked into much, but I do notice
the same behavior.  I have my main IP as 177, but my mail server is
published on 130.  Any outbound email appears to come from 177 though.
My guess is that all outbound traffic originates from the "main" ip
address of the server.

Sorry I'm not more help, but I at least wanted to validate what you have
seen.

No thoughts on this? Has anyone else seen this behavior from an SMTP
server published behind their ISA?

Hi,

I have my isa server publishing an smtp server with an external address
of x.x.x.153

My ISA server default ip is x.x.x.130

My PTR record pointing to my mail server is x.x.x.153

Why when I receive emails to an external account, do I see the ip
x.x.x.130 in the header info?

This scares me as it seems it could cause problems... I am looking at
the header granted in the options in outlook, so it could be leaving
some interaction between the mail servers out...

Any thoughts on why this would occur?
