Last time I tried on a so called modern hardware (HP DL380 G4, two Xeon
3.6 GHz, 2 GBs of RAM and a slow RAID card, which can do about 80-90
MBbps) postfix and cyrus could sink about 1200-2000 emails per minute.
All of messages were sent through an amavisd which then fed it into
Amavisd was slow like hell, but cyrus could easily put email down to
disk at a rate of 10-15 MBps.
Take the above numbers with a grain of salt, because the testing was
pretty lame (an email emitter program which fed postfix through
localhost smtp and a frequent mailq, to see if there are messages in the
postfix queue) and all the numbers are from my mind...
