----------------------------
Summary: Log cluttered by ManageSieve errors
Key: JAMES-4206
URL: https://issues.apache.org/jira/browse/JAMES-4206
Project: James Server
Issue Type: Bug
Reporter: Felix
Every proper logout of the ManageSieve server writes a log message of severity
`WARN`
Here is an excerpt from the log for one regular ManageSieve session:

I am currently working on a fix that catches this Exception to produce a single
INFO line in the log.
