Hello Matthew,
Thanks for the info.
I am sorry I did not word my question properly - what I meant was:
Can somebody please tell me how to implement quotas using courier-imap and exim with virtual user maildirs?
OS quotas solve quota issues for real system users; but how do you enforce quotas for virtual mail users?

Quotas aren't provided by the mail software -- they are a function of
the filesystem that you store the mail on.
To set up quotas:
i) Make sure quotas are enabled in your kernel configuration:
options QUOTA
It's not in the GENERIC kernel for 4.x. If you don't want to
rebuild your kernel, you may be able to kldload(8) a quota
module -- see loader.conf(5).
ii) Enable quotas on boot up. Add:
enable_quotas="YES"
check_quotas="YES"
to /etc/rc.conf
iii) Mark the file systems you want to use quotas on in /etc/fstab
by setting the appropriate options in the mount flags.
/dev/ad0s1e /var ufs rw,userquota=/var/quota/var.user,groupquota=/var/quota/var.group 2 2
See fstab(5) for details.
iv) Now either reboot or run the following commands while the
system is fairly quiescent:
# quotacheck -a
# quotaon -a
This will scan the disk partition (can take some time) and make
a table showing how much space is being used by each user and
group. It will then enable, at the system level, hooks into
the low level filesystem calls that updates that table whenever
the filesystem is written to. See quotaon(8) and
quotacheck(8).
v) Now the quota system is up and running, and you can use the
quota(1) and repquota(8) commands to see how much disk space is
being used by each user. However, you haven't actually set up
any limits for any users yet. To do that, use the edquota(1)
command.
Your mail programs will automatically operate within the quota
settings you set up, and handle the EDQUOT errors the system will
generate if the user receives over-much mail.
Cheers,
Matthew
