-22 but mailbox is NOT full!

[slinky]

For the past few days I haven't been receiving email. After looking at the queue, some of my accounts are stuck due to an error - but my account has plenty of email space as does the domain quota.

Myemail@mydomain.com T=virtual_userdelivery defer (-22): mailbox is full (MTA-imposed quota exceeded while writing to tmp/123456.H23445678.myservername.mynameserver.net.

I'm remote atm so this is a double problem and hopefully someone can diagnose why one of these accounts just doesn't deliver mail. Many thanks in advance.

Make sure your /tmp partition didn't exceed its quota/not full.

This has to do with individual POP3/IMAP account quota's. The master/overall domain may not be over quota but each individual account has a quota. You access this via cpanel's mail accounts page and not whm.
