Anthony, if your domain exists, then can you run a lookup on the actual box? For instance, obviously planetwe.com exist, but you can't run an nslookup on leila.planetwe.com - so you can't send mail from it without having it masquerade as planetwe.com: (from sendmail.cf) # who I masquerade as (null for no masquerading) (see also $=M) DMplanetwe.com this allows me to send mail as drew@planetwe.com. It looks like you probably have a similar situation. -- Drew Sanford Systems Administrator Planetwe.com Email: drew@planetwe.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
