Mmmmhh then the only other thing I can think of is that awhile back I think Len mentioned that some providers may give you a static IP address out of a dynamic block. IF that dynamic block is being blocked by your recipients mail server then you will see exactly what is happening. If Len sees this he may better explain.

My email server was 199.44.118.2 but when it went out, it went out as 199.44.118.253. This worked. Under the PIX, my email server is 199.44.118.2 and it goes out as 199.44.118.2. Hank Maybe I didn't say this right. When you send mail you are saying the traffic goes out on ip 199.44.118.253 because of the firewall. Yet your mail server dns.mgtamer.com has an external ip of 199.44.118.2. Earthlink is looking at this as a change during the communication. It says hey you announce yourself as 199.44.118.253 but when it tries to establish a connection back it sees the 199.44.118.2 so it feels it is either an ip spoof or a dynamic address because it doesn't report the same ip in both instances. I had this happen to me with a customers email before. All of my email was being rejected until I corrected the dns issue. So if you change the dns on your mail server to report 19.44.118.253 it should work. --- [This E-mail has been scanned for viruses.] [MGT of America, Inc.] 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/ 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/
