Not that I can think of. There are too many variables to consider. Do
people leave mail on the server? How large are the spool files? How
often do the users access mail?
To give you an idea, my system hosts about 2000 users. We get around
45,000 transactions daily. Average spool file size is around 3
megabytes.
/var/mail is striped and mirrored across 4 10,000 rpm drives and two
controllers (single ended ~40 mbs transfer). Poptemp is on a single
10,000 rpm drive. We do not use server mode as many users run pine.
Qpopper 3.1.2.
This setup hums along nicely.
