I can't think of anything - I'm not sure I like the '_' in the hostname 'mail_server.primaryuk.com' - but my NT machine here was OK about it... Have you checked they can resolve that name on their Mail Exchange machine? Does it return any other info? - What software are you using to deal with this? Sendmail? - Theres a lot of sendmail info at www.sendmail.org, and they also have their own Newsgroups / mailing lists etc. if you get stuck... -Karl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
