I must say, if you're implementing a server with no pre-existing users on it (as it sounds like you are), I can not recommend anything _but_ MySQL. If you have high-speed disks (U320 15k RPM), as I am sure you do at the ISP level, then the buck stops at MySQL, IMHO. I also think that Postfix is a mighty fine MTA and integrating it with MySQL is really easy if you follow the docs on gentoo.org.
