One of my users stopped receiving e-mail recently. According to [b]/var/log/mail.log[/b], all delivery attempts on his behalf were being deferred. I logged into [b]SquirrelMail[/b] and it told me his mailbox was at 100% of his quota.

In [b]Server Admin > Mail > Accounts[/b], however, he was supposed to have 19% free space remaining.

[b]/usr/bin/cyrus/quota[/b] was saying the same thing: 19% free space remaining.

Then I tried [b]/usr/bin/cyrus/bin/cyrus-quota[/b] and it told me what [b]SquirrelMail[/b] was saying: this guy was over his limit.

I used [b]WorkGroup Manager[/b] to increase his quota so he had room to delete his mail.

The quota change had no effect. I stopped and started mail services. His quota remained at the previous level. I even tried to change his quota with [b]cyradm[/b]. It had no effect.

In the end, I managed to purge a bunch of space-hogging attachments to make his mailbox operational again.

I have two questions:

(1) What is the difference between [b]quota[/b] and [b]cyrus-quota[/b]? One is wrong and one is right. Unfortunately, it appears that [b]Server Admin[/b] is using the wrong one. Plain ol’ [b]quota[/b] used to work just fine. I know because I used it in a script for sending periodic reminders to users who were edging too close to their limit. I’ve had to switch it to [b]cyrus-quota[/b] so the notifcations work again.

(2) Why didn’t my quota adjustment in [b]Workgroup Manager[/b] take effect?

I’m beginning to think that the incremental security fixes that Apple releases are starting to create a small disconnect between the GUI admin tools and the server itself. Given 10.3.9 server’s age, I’m afraid Apple’s not paying enough attention anymore.
