> Thanks - I'll check with the ISP in the morning. Don't bother calling the isp and wasting your time until you've found out if the isp is indeed blocking port 25. Find out by opening a command window and issuing: """ c:\>telnet mail.paulmcnett.com 25 Connecting to mail.paulmcnett.com...Could not open connection to the host, on port 25: Connect failed """ Okay, so my ISP (AT&T DSL) is blocking port 25. Actually, it could be one of my firewalls but I happen to know that isn't the case.[1] Point being, I can't get out onto the internet on port 25 (smtp). If I had gotten out, I'd have seen: """ c:\>telnet mail.paulmcnett.com 25 Connecting to mail.paulmcnett.com... 220 mail.paulmcnett.com ESMTP Postfix """ If you find that your isp does block port 25, your options include setting up a relay smtp server. I've set one up for my use, that listens on port 8025 (try telnetting to mail.paulmcnett.com 8025). This allows certain clients of mine behind restrictive isp's to still have mailservers in-house that relay over 8025 to my server that actually sends the mail. [1] If I didn't know that was the case, I'd bring my laptop over to the dsl router, and plug it in directly, and then I'd go to my OS's firewall and temporarily disable it, and try the telnet test again. -- pkm ~ http://paulmcnett.com _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[EMAIL PROTECTED] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
