where xxxx is the offending user name. The error repeats at random intervals, I guess related to the activity.

Since we are using Horde 5 on the front end we get the following errors from it:

We believe these are related to the above Dovecot error since they happens together.

Is this a Dovecot problem?
Config attached.
