Why would you need a new mailserver?
The old one is working just fine 
[root@mailserver log]# uptime 09:48:57 up 34 days, 22:47, 1 user, load average: 82.75, 52.72, 37.23
I’ve never seen such a load before…

raven:/home/support # uptime
12:04am up 15 days 14:13, 3 users, load average: 322.03, 148.19, 59.00
That is the load on an ssh server that establishes 300~ ssh tunnel connections at 12:00.
Nice! This was ony the flushing of a 10000-mail queue
So _that’s_ where all that spam is coming from … ;^)
A few years ago we disconnected one of the workstations from ethernet for a couple of days, because we had a guest at the office and did not have enough Ethernet cables in place. When we connected it back it was not responsive. After I managed to log in, I saw a load of 800. That’s what you get when 4000 cron scripts all try to complain at the same time about a NFS-mounted directory being unavailable.
A couple of ’sudo postsuper -d ALL’ sped things up somewhat. Only about a thousand of emails ended up in my inbox.
Postfix with OSBF-Lua (http://osbf-lua.luaforge.net) work like charms, look:
1 amartins@wks05:~ % uptime
12:36pm up 1521 day(s), 17:50, 3 users, load average: 0.81, 0.59, 0.55
