目的：有一台openmail主机(HP-UX)，它的出口是教育网，
另有一台普通sun solaris主机，它的出口是chinanet，
由于教育网出口小，想在不改动Openmail网络位置的前提下，
实现当用户发邮件时，实际上邮件的出口走的是sun这台主机。

1st setup the chinanet machine to accept relay for hp-ux
in /etc/mail/access add:
chinanetHostName RELAY
Then setup the hp-ux machine to relay mail to the chinanet one
in /etc/sendmail.cf add or change:
DR hp-uxHostName
CR hp-uxHostName
# forward mail to relay host
This for sending mail. For receiving mails i think you'll need to
set up a virtual domain for sendmail which is beyond sendmail.cf..
Tho there're instructions in http://www.sendmail.org/virtual-hosting.html
you can checkout.
