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? -----Original Message----- From: Aaron Spurlock [mailto:aarons@xxxxxxxxxxxxxxxxxxxxxx] Sent: Thursday, May 09, 2002 3:58 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: smtp issue - Anyone? http://www.ISAserver.org 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. -----Original Message----- From: Bryan Andrews [mailto:bandrews@xxxxxxxxxxxxxxxxxx] Sent: Thursday, May 09, 2002 12:43 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: smtp issue - Anyone? http://www.ISAserver.org No thoughts on this? Has anyone else seen this behavior from an SMTP server published behind their ISA? -----Original Message----- From: Bryan Andrews Sent: Wednesday, May 08, 2002 6:14 PM To: [ISAserver.org Discussion List] Subject: [isalist] smtp issue http://www.ISAserver.org 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? ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: bandrews@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: aarons@xxxxxxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: bandrews@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
