A few questions.
1. What is your email program (like IE for Hotmail/gmail, or Thunderbird, or MS Outlook or Outlook Express or Eudora)?
2. Try it after booting in Safe Mode. Does that work?
3. What is your antivirus, and is it set to check outgoing mail? See what happens if you uncheck that?
to e-mail messages. It boots me out quickly when I try to do this. What could be causing this? My virtual memory is almost full but physical memory has lots of RAM. Could that be an issue or maybe a virus or something else?
