I have a small Squirrelmail server, using Postfix & Dovecot. I am trying to limit the amount of mail a user can get. The "mailbox_size_limit" value does not seem to be being honored. I am using the Maildir directory format.
From googling, it appears that "mailbox_size_limit" applies to a
single file (mbox format?), and that it does not work with Maildirs. Is this correct?
How should I limit the Mailbox size of the users?
I'm not very familiar with Linux "quotas", but I think that is my only other choice.
