How do you setup a static route for that situation? In qmail, there is this file /var/qmail/control/smtproutes specifies how mail destined for different domains are handled. I have 'freebsd.org:mail.myisp.com' in it to override MX lookup when mail is for freebsd.org. Instead, qmail forwards the mail to mail.myisp.com. > > Choices like that cannot be made until you understand what > > your limitations are and what your ISP can do.

For example, if your SMTP port is firewalled by your ISP, then you have no chance of hosting your own mail. Once you understand the whole mail concept, then what your ISP is doing becomes apparent. At that time, you can make an informed decision as to how you can best utilize their infrastructure. --- Samuel Chow cyschow@shaw.ca Segmentation Fault (core dumped) This message is displayed using recycled electrons.
