Mail Delivery Subsystem (Spam!)

[adigit]

Dear All, please help!

I set all email forward for XXX@abc.com to my gmail inbox via ISPCP a few weeks ago. it works well. but recently, I keep receiving emails like the following these days. Is there anything should be tuned to avoid this? ISCP or SMTP or anything else, pls?

maybe i should point out clearly that the problem is
"I never created accounts like michael274@abc.com, colette-Kluke@abc.com ......"

Spammers frequently fake sender adresses. If you look at the returned mails you'll recognize that they have not been sent through your server.
