The smmsp are sendmail accounts AIUI, so not quite sure what is going on - is it relaying for machines using sendmail by any chance? Either way you probably want mail.mydomain.co.uk in mydestination i.e mydestination = mydomain.co.uk, mail.mydomain.co.uk or mydestination = $mydomain, $myhostname I prefer the explicit syntax, depends how adverse you are to editing in future when you rename stuff. Of course there has to be some delivery for relevant addresses although probably it'll use /etc/aliases if you haven't fiddled with the defaults too much, and hopefully that has a postmaster and similar. > Finally I've also noticed some access denied requests.

The good news is that IPv6 address space is REALLY big (and empty) which makes scanning it much harder work so the bad guys will have to do something less mindless. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
