smtproutes. I've been thinking about changing it from smtp to qmtp too,
since qmtp seems to be made for this kind of thing, but I haven't had the

Yeah, that's what we were thinking on the MySQL side of things... A few
replicated MySQL servers with lots of RAM and RAID. We use round robin DNS
to split load between our inbound MX servers, but I don't think that would
work for authenticated services like IMAP and POP3. That's my big concern

Right now maybe 1500-2000 or so users, and about 1.5 million messages/day.
This amount of load is handled pretty well by our current setup, but I
expect in the coming year to be well over 10k users and probably 6 times
the message volume, maybe more. We're rolling out a new fiber Internet
access product that includes email service for buisness, and I expect a
lot of new load from that.
