I don't know of a way to do this with QMT (which isn't to say it can't be done).

I understand your concern, but this restriction doesn't sit well with me. I think it's a bad solution to the problem you're trying to address. I think it would be better to change compromised passwords. Also be sure that SSL/TLS is always used with client configurations for smtp, pop3 and imap.

Hi Eric,

I don't think so eMPF can do this. Basically it should not allow other user to send mail or it should do some thing like google smart host i.e. from id in headers should automatically replace by authenticated email id while delivering mail to reciepient. If this patch is done then it can be helpful to stop spammers who are sending mail with compromise username and password.

Regards,

Amit

    I don't know off hand. Is there an eMPF policy that can handle this?
