I am using Dovecot, but have been unable to get either it's maildir or
dirsize quotas to be enforced.
It does not seem to prevent the user from receiving emails. I set the
limit to 10MB, and was able to receive more than 12MB in emails. I
restarted dovecot after making the changes below. Is there something
else I need to do?
nano -w /etc/dovecot.conf
protocol imap {
...
mail_plugins = quota imap_quota
...
}
plugin {
...
# 10 MB + 1000 messages quota limit
quota = maildir:storage=10240:messages=1000:ignore=Trash
...
}
