Key. You need to have a HOSTS entry for aquesthosting.com and erinhope.com, not mail.aquesthosting.com and mail.erinhope.com. You might need the MX record in the HOSTS file as well, although Len can answer that better than I can.

You need to have a zone for aquesthosting.com and erinhope.com on that internal DNS server. > telent to mail.aquesthosting.com:25 or 10.x.x.x:25 - both return "could not open > connection to host" > telent to mail.erinhope.com:25 or 10.x.x.x:25 - both return "cold not open > connection to host" Did you try telnet? Try using "telnet mail.erinhope.com 25" Note the space, not a colon. Colon only works in IE.
