There are four possibilities I can think of off hand:
* Someone else is using your computer. To solve, make sure you have to enter your password to login. (Not automatically remembered.)
* Someone else has your password, and is using your account to send spam. To solve, change your password, and make sure it's not easy to guess.
* Your computer has been infected. If you use MS Outlook, Thunderbird, etc, "guests" can use the account to send out e-mail to random addresses, making you the spammer. To solve, scan your computer thoroughly with antivirus and antispyware programs.
* Most likely, someone is spoofing the e-mail address. Basically, this means someone else is making it appear as if mail is coming from your account, when in fact it isn't. This is fairly common (happened to my "junk" accounts several times), and hard to deal with. If the e-mail service is paid (AOL, Yahoo! Plus, etc), you should notify the provider immediately so they can take the appropriate action. If it's a free service, your best bet is to simply change your e-mail address. Afterwards, be careful who you give it out to and keep a second "junk" account for use when signing up for subscriptions/downloads or participating in forums.
Hope this helps,
