About why they're rejecting you, or about how others are getting through? For the first, RFC2821 (SMTP) says the argument to HELO and/or EHLO must be a fully qualified domain name, or an IP address literal (like [66.35.250.206]). So you're not being RFC compliant by using bare 'artarmon', and they're being strict about it, done usually as a spam/virus filtering measure. For the second, the MTA can do a regex/string check or can do an actual dns lookup - if they're doing a dns lookup things like localhost will pass, of course, unless specifically excluded. Other generic barenames sometimes get passed too that way - 'mail', 'mailhost', etc. Cheers, Gavin -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
