I get the message: server imapd-ssl: Error: Disk quota exceeded for one of the sites that I host. I had that site set to a quota of 200MB (which it was over). Since, I have increased the quota on the site (user had no quota that I had set up anyway) so disk space from that perspective no longer should be an issue. Any ideas what I need to do next to get this resolved? The users can send (and receive) e-mail but it's not saving anywhere (Sent, Trash etc) other than their Inbox. Update 17:38 : After waiting for a little while those users were able to write again so I guess it's a matter of a little patience.
