Title: SMTP errors from my system to one of my Imail servers

Hmmm...   Are you on the same subnet with these servers? Are they firewalled separately from your internal LAN (i.e. DMZ)? What does a tracert to the servers show? Can you connect to other services on IMail1? Are you attempting to connect by IP, NetBIOS name, or FQDN? Does your local DNS cache have a different IP? Can you connect from another PC on your LAN?

A little more background. 1)       Imail 2 is using port 25 as well. I can telnet to it without issue. It’s only Imail 1 that gives me issues. 2)       I host these servers myself so I am my own ISP. To get to these servers I need go no further than my own firewall.   The trick of this is that, to my knowledge, nothing has changed on my firewall or my network.   Troy D. Hilton Serveon, Inc.

I cannot send using Outlook or Outlook Express thru Imail 1 but I can if using the Web Interface. I also cannot telnet to Imail 1. I get an error message that port 25 is being blocked. Now, my other server, Imail 2, can send emails just fine. I can telnet to it without issue. Let me also note that Imail 1 is my hosting mail server and is used by hundreds of folks. No one has contacted me in any way to complain which leads me to assume that it’s me. I’ve scanned my system for spyware and such and the only thing it found was a bunch of cookies and WildTangent, which I removed. I’ve tried disabling my McAfee AV software’s email scanner, I’ve rebooted my system, all to no avail. While I am running XP Pro I am not running SP2 and do not have the XP firewall active. Any thoughts on troubleshooting this? Thanks! Troy D. Hilton Serveon, Inc. [EMAIL PROTECTED] 302-529-8640
