Re: Sieve mailet error

Hello Mihai,

My bet is that you are among the first user to use the Sieve mailet...

I succeeded to reproduce the behaviour you describe in unit tests, and 
fixed it.

Here are the Jira tickets: 
https://issues.apache.org/jira/browse/JAMES-3913 
https://issues.apache.org/jira/browse/JAMES-3914

Here is the github PR: https://github.com/apache/james-project/pull/1589

Many thanks for the report.

This will be part of James release 3.8.1.

Regards,

Benoit
