Spam Mails

Spam Mails

Hi Guys, i recently noticed all sort of spam/scam mails on my inbox. I blocked the mail addresses & domains on anti-spam setting, but the same emails kept coming back to my inbox. This is serious as the spammers are using my email address to spam people. For example; the header of the spam mail will shows "ACCESS BANK" < john.doe@mydomain.net>. Asking people for their pin numbers.

Kindly recommend the best solution for me to deal with this situation.

Thanks
