Problem with domain_edit.php

[kilburn]

If the message is correct, then it means that you're trying to set the limit of e-mail addresses to a number lower than the number of mails that the user already has. Therefore, the panel is telling you to either:

(1) Choose a higher number of e-mails as limit
(2) Remove e-mail accounts from this domain until the remaining number of emails is equal to or lower than the limit you're trying to set.
