I'm sure that qmail can do that easily as well -- this number does not
sound unreachably high to me... What kind of machine are we talking
about?
1. OS -- Slowlaris, FreeBSD, Linux, ???
2. Hardware -- SCSI type, etc.
3. OS setup. Are you using softupdates or async mounts? Is the queue on
its own spindle, how fast is the queue spindle (RPM + SCSI bandwidth)?
etc., etc.

I'm sure it is*. Let's see what you've got for config first...
* As long as they don't do something horribly broken like maintain all
queues or queue state in RAM, or something else equally silly.
