Please help: My email is being flooded w/returned email sent by spammers using MY url

[Dabbi]

Hello,

My inbox and spam folder is being flooded with mail undeliverable type messages. When I checked a couple to see what the "from" was it shows it's from a totally fabricated names using MY domain. (ex: sochoh@thehowcafe.com)

I'm extremely anti-spam and spammers and am livid about this. I know it's not actually them getting a legitimate email addie with my url since I just double checked my cpanel. Is there a way to stop this flooding and is there any way I can prevent them from doing this in the future? The last thing I want is my site to get a bad rep for spamming.

Help would be truly appreciated & please keep it as simple as possible since I'm still relatively new and learning server care, etc.

Thank you!
