Are there any risks I need to worry about > with the default configuration of sendmail? It's pretty good, to be honest, and works well as a leaf-node. There are a bunch of self-explanatory files in /etc/mail. Except, of course, for the sendmail.cf file :-) You'll probably want to edit /etc/mail/access .../aliases .../local-host-names .../virtusertable (if you're hosting multiple domains) However, sendmail is something that it's worth keeping up-to-date. This is pretty simple to do if you're using cvsup. There are a bunch of alternative mailers (qmail, postfix, exim) all of which are reasonable alternatives. Sendmail configuration can be a bit thorny; I'd recommend you play and come back with specific setup questions. -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287088 Fax +44 (0)117 9287112 RFC822 jan.grant@bris.ac.uk and Nostradamus never dreamed of the Church of the Accellerated Worm To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
