I don't get it. If Sendmail doesn't do a DNS lookup on receipt of the mail how does it know which domains are not 'local' (I'm not using a smart host but I do have a macro for my official domain name `Djwew.co.uk')? I'll need to have a look at this in more detail, meanwhile if you've got any URLs / suggestions, do let me know.
