Hello all,
I am looking for a way to spam-check outgoing mail, so the users registered with my server cannot send out spam (or viruses).
My server is using squirrelmail for sending e-mail, so the mail is generated on the server and sent directly using SMTP (in squirrelmail you may choose between using SMTP or Sendmail).
Bad idea. A ISP I worked at outsourced our e-mail to a company that did that - you wouldn't BELIEVE how many complaints / calls we took for it. Some of it was because our customers were e-mailing Taiwan, Japan, etc - and boom, instant spam block. Some of our customers sent out newsletters to their clients - boom, instant spam.
I think the best policy / setup is to have a ZERO tolerance spam policy - you spam, you're gone.
