He sayed, he has 5000 mail users...
I have here in Kehl/Germany on my server currently arround 700 users and
they have per day arround 140.000 mails. the problem is, 90% of the
mails come in 05:00-09:00 and 16:00-19:00 I have peeks of more then 30
messages per second using a 1GE.
Oh yes, I am using courier-mta/imap and the random writes are very heavy
which mean, I would kill a SSD with the writes in less then 6 month...

WHO want to risk the mails from customers?

I am using a courir-imap-proxy (Sun Fire X4100), courier-mta (Sun Fire
X4100), two Sun Fire X4100 as spam/virus filter and currently three SUN
Fire X4150 with 1 CPU and 16 GByte of memory as mail storage server.
The first two run from SATA-CF-Drives the filter has each three 76 GByte
drives and the storage servers (not only mail) use 147 GByte (Raid-1 +
Hotfix for Data) and seperated small Raid for OS.
Thanks, Greetings and nice Day/Evening
