it's about the tutorial: Virtual Users + Domains With Postfix, Courier + MySQL (+SMTP-AUTH, SpamA, ClamAV) - i followed it without installing spam-filters.
Everything works fine, except that quota doesn't work. If i set the quota to 1 and send then an email to this mail account, the mail is normally delivered to the maildir.
same thing if i copy an email from another imap-mailbox to this mailbox: no quota error....
can anyone help me?
