Lorry, I think "stmp-server.mn.rr.com" should be "smtp-server.mn.rr.com", but that may be just an email typo. "s3.quintessential.com" and "slava.net" both resolve to "209.98.180.234". It is running "qmail" on port 25. "smtp-server.mn.rr.com" resolves to "24.94.162.235" and is running an MS SMTP mail server on port 25. If you get frustrated enough to try and manually troubleshoot the problem, here are some references: http://RFC.net/rfc821.html http://RFC.net/rfc1869.html http://RFC.net/rfc2554.html on SMTP, ESMTP, and SMTP AUTH respectively. You can telnet to port 25 on an SMTP server and try and carry on a conversation (and send mail) using the info from these docs. Maybe you can see where things fall apart. There may be more concise documentation, but probably none more authoritative. Good luck, Troy >>> fish at slava.net 10/10/01 09:59AM >>> OK, here are some things I have tried: slava.net s3.quintessential.com stmp-server.mn.rr.com
