I remember reading something back in 1999 on this list something about
setting up email service at an ISP with multiple POP's in the following
configuration, with 1 domain name:
MX1/POP1 MX2/POP2 MX3/POP3
Florida Oregon Nevada
Each POP would be a separate city, and need to have their own SMTP server
and own POP3 server so that POP3 and SMTP traffic isn't backhauled across
the internet to the main mailhub. What would happen is each SMTP server
would have a usermap containing the $local_part and mailhost. All
mailservers operate POP3 for the same domain. So if john@???
existed at MX1, but the message arrived at MX3, then MX3 would relay the
mail to MX1, and drop it in john's pop box.
Does anybody know how to make this happen?
