I'm runnign Zimbra OS 4.5.4 on an Ubuntu server. The last change to the server was when I upgraded from 4.5.1 to 4.5.4 about 2 weeks ago.

Just today I started receiving the following pop-up error message when clicking Get POP Mail:

"system failure: writing new object of type 5".

It gets 3 messages from the pop-account but does not clear those messages. When I click Get POP Mail it repeats this process (same 3 messages duplicated and then the error message).

I'm guess the next step is to get a different e-mail program installed so I can download and examine the messages in the POP mailbox...? Anyone else run into this problem?
