hi all,

one of our clients is receiving lots of spam mail, mostly due to broadcasting almost all email addresses on their contact us page.
Even I told them to remove those addresses they did not :)

they are mostly pissed of receiving spam where the from address is their own domain, but the mails are sent from out of server.They receive mails from addresses like [email protected]

Is there a way to block these messages, Is it the reverse host lookup I have to enable to avoid this?

Regards.
