Could you expand on the hardware issues your talking about? They way I plan to have it is that a SMTP connection comes in a Linux Virtual Server "Director" directs it to the lesser used server and the server running DBMAIL and PostgreSql then takes the connection. From there Postgresql then is clustered with the other server and all data is sync'ed up

Hardware problems are what made me switch to just a master mysql server running dbmail, postfix, etc and a slave only has a data backup. Sorry if I was not clear on that part.

I ran an ISP that handled over 6,000 messages per day which is nothing for a moderate ISP. figure at least 10 messages per day (including spam) per user. If you've got 3500 users that's 35,000 messages. (35,000 / 24 = 1458.33 per hour.) 500 messages per day limit due to hardware is pretty pathetic. I ran the 6,000 messages per day on Linux on a K6-II 400 w/512MB of RAM and sendmail. I've just put two systems together using Postfix and dbmail. One of them is on very modest hardware about to be upgraded (Celeron 1GHz/ 1GB RAM - don't go there.) the database is on the same machine MySQL). The other is running on Athlon 1GHz 1GB RAM and the database is on a separate machine (Pentium IV 2.8 GHz 1GB RAM running Gentoo Linux and MySQL). My assumption is that I can run multiple mailservers against the database server. The dbserver also performs DNS using powerdns (also a MySQL backend.)

It ran very strong for about 6-8 months before hardware issues got in the way. It was handling a 500message per day average with the bulk in the morning (SPAM). I am now down to 1 primary and 1 slave and no fail-over. I had no special setup for DBMail, only special setup with the util (ucarp) to do failover... Hope this helps.

Does anyone have anything like this running and if so can they provide some info about how they did it?
