Eep. 25000 mail accounts == 25000+ entries in your /etc/passwd,
and 25000 files in /var/mail. Although you did not explicitly say all
25000 mail accounts had to be on the same machine, I would recommend
splitting that up into different mail servers. Divide the students
into faculties or degree major or whatever. Then have a separate host
for each and tell the students which machine to use to retrieve mail.
If you want a consistent address for all the students, set up a
separate mailhost that routes incoming mail to the proper machine
based on a username lookup table. I don't really see any technical
problems with having 25000 mail accounts on one machine, but that can
mean a *hell* of a lot of disk space...
