trouble sending e-mail

[Casi]

I can receive e-mail but I cannot send it. When I try, I get an error message
saying possible server problem or network problem or a long period of
inactivity. I confirmed with Time Warner cable and there are no problems
showing up on that end. I am able to sign on to webmail, so it is not a
password problem. What is my next step for finding the problem?

1. Post the entire error message here... right-click on it, select Copy.
Then paste it into a reply.
2. Did it work before?
3. What anti-virus software do you use?
It could be your antivirus or anti-spam software interfering.

Dave,

Trend micro antivirus came on this computer. The error message I'm getting
is below. It just started doing this out of the blue about a week ago. Please
help!

Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Subject 'Re: Annual Pledge Drive', Account:
'pop-server.austin.rr.com', Server: 'smtp-server.austin.rr.com', Protocol:
SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0F

"Unexpected" termination is almost always caused by your antivirus.
Trend Micro antivirus is among the top three troublemakers for Windows Mail.
First, go into its settings and disable any interaction with email, then try
Windows Mail again. If no improvement, do a trial uninstall of the antivirus.

Another option (instead of uninstalling Trend Micro) is to upgrade to
Windows Live Mail, which is more resistant to the adverse effects of
overly intrusive antivirus products: http://download.live.com/wlmail

In any case you must disable any antivirus email scanning, for the reason
