operation. I would like the system to include the SMTP server, =
IMAP/POP, Spamassasin, Squirrelmail, and a Mysql database for =
For scalability and speed, I intend to spread this across several =
machines. I was thinking the above would be 5 separate servers.
If you have some thoughts on a system design, email me. I would love to =
hear comments and suggestions. I would also like suggestions on what to =
run for SMTP transport, and IMAP/POP.
