I am interested in limiting the mailbox sizes of my users without using
kernel quotas. This is so because the only file that my users own on my
systems is their mailboxes (residing in /var/spool/mail). Since my
sendmail invokes procmail to deliver the emails to my users, I was
wondering if procmail could automatically determined before writing to a
mailbox if it is over a certain size limit? Has someone been to this
area before?
IMHO, if procmail could provide such a facility, sendmail/qmail servers
can be build up that can support tens of thousands of users WITHOUT
slowing down the system (because of the quota checks that the system
performs at each and every disk write operation).
If this hasn't been done before, I intend to modify the source of
procmail to get this done. Any one interested to join in this exercise
is welcome.
Best Regards and thanks in advance

Thanks!
