Username refusal

[Slider]

Hi all!

I am trying to refuse mail from any address that starts with
[EMAIL PROTECTED] The TO: address is fine although the FROM addresses are
[EMAIL PROTECTED] I do not want to ban the WHOLE domain.com (in
BADMAILFROM) as there are legitimate users there mailing to my users! I just
want to ban all FROM addresses that start with "nobody"!

Any ideas?

Thanks
