And make the passwords complex.. Thirteen characters with both lower case and upper case letters, numbers, and other characters, trying not to use any dictionary words when creating the password.

I'll suggest that someone guessed correctly at your current password and was able to login to your current email. Either that, or there's a virus when is infecting someone else's computer to which you've previously sent email to.. In case where you forward email to all your friends, each one of those friends now has a full listing of all your email contacts.. Certain types of viruses are able to grab such information on infected computers and send out SPAM messages by SPOOFING the "From" line in the email. The add YOUR name to the "From" line and it appears as though they all came from your email address when they may not have.

Hope this helps.
