I rececently had a high speed DSL line installed in my office. Everything works fine EXCEPT now I can't send any mail. I can receive from our pop server (hosted by Yahoo) but I can' send. I keep getting the error message "SMTP server not found". I don't know what else to do. Can you help?

I should have told you this: My web site is being hosted by Yahoo. Therefore all of the email accounts are through them. So I can't reset the SMTP server. Also, When I try another ISP account that I have and try to send using their SMTP server address, I get the same results. We are using Microsoft Outlook as a mail client. Could the answer be in there somewhere?

Some ISPs are blocking outbound SMTP traffic to servers other than their own. That would mean you would not be able to connect to the SMTP server ran by Yahoo (smtp.yahoo.com ? )
Check your ISP and see what their SMTP server is. Configure your Outlook client to send mail through their server (using the e-mail address you received from your DSL ISP when you signed up). You will probably not be able to send e-mail using your yahoo e-mail address through your ISP's SMTP server (that would be spammail, technically).

hope this helps

In addition to Answer 1.

You may be able to ping the server but try connecting using ftp to port 25 on that server. Port 25 is the SMTP port.
