I missunderstood Steve's prior question. If the email comes from a non-existant domain (that is one that isn't registered with a registrar) then you can filter this at the MTA level. In postfix the setting is "reject_unknown_sender_domain". Your MTA might vary. This doesn't depend upon a www or any other name actually pointing to a server. The existance of the domain with the registrar and an MX record qualifies it as a valid domain. My opinion is that you should drop this at the MTA level as only spammers of people with really badly configured emails servers do not send email with a fully qualified and valid domain. But that's my $0.02. Gary Smith

I have several clients for which we host email but no website. Not even a placeholder one. cheers, Colin Colin A. Bartlett Kinetic Web Solutions www.kineticweb.biz
