I just found out today my email address is sending out spam. Today I found an email in my inbox telling me he or she isn't my friend and never will be and to stop sending it spam and called me a nasty name. Then it said don't bother replying because he or she has my address blocked. I was confused and didn't know who this person was and I don't even use my hotmail account much.
It is possible that your computer has been hijacked by malware that sends email to your contacts and to random addresses. It is possible that your email account has been cracked (i.e. someone has guessed / found the password) and is using it to send email.
It is also possible that the sent emails have nothing at all to do with you or your account, but someone has a list of fake and real email addresses, including yours, to send spam. You can ask your friend who has received real and spam email from you to compare the headers in two of these emails - something like View -> Message source - and look through the chain of Received: lines near the top, for the last-named server. Both messages will come from the same or similar servers.
It is a part of the specification of email servers that anyone can send an email out through their server with any From: value at all (the sender does not need to be authorised, or registered with that server, or registered anywhere), which simplifies sending email while mobile, but makes spam very easy.
I have some spam here, where you can see that the From: is a (real) Gmail address while the last-named Received: server is actually a Yahoo! server, so it was not sent from Gmail at all:
