Like to think I'm a little bit beyond this :) Over the past 30 minutes (Friday afternoon mail load) we've seen this usage: SMTP: 41% Idle: 29% Queue: 19% Web: 3% POP3: 1.5% Other processes: 6% As you can see the SMTP process is taking almost 50% of the server's time. > > >The 2.8 machine is coping with this load, but only just.

The load is one concern, which may be a false one if the hardware can handle 10 times what it's currently finding strenuous. I basically feel I can trust postfix/Debian to handle spam/viruses faster than Imail, and it would be 'nice' technically, imo, to have a relatively clean mail source for the Imail box to process.
