Hello, Quickj Noob question. I was wondering if it were possible to spoof someones e-mail account to send out fake e-mails. The reason why I ask is because I keep getting these Virus e-mails from a person(s) using my domain name's e-mail addresses.. I know it's not an actual e-mail address (since I'm the only person who can authorize a new e-mail account), but it's starting to make me worry. Specially if someone spoof's my e-mail address to get someone else's information (password, etc).

Anyways, I have no idea what to do.. If *anyone* can help me in any way I'd appreciate it so much.

Edit: Please note that I did NOT send any e-mails (nor any of my friends with their e-mail accounts) like this before. I never sent any message with the subject "Re: Thanks "
