Since last week, the new sieve-filter command line tool, which is 
intended for just such a task, is part of the normal compile output for 
Pigeonhole 0.3.x for Dovecot v2.1. Unfortunately, it is not released 
yet, so I guess you're stuck with your old getmail-based solution for now.

The tool is still experimental and I must say that I have not tested the 
preservation of flags for some time and many changes were performed 
since then. I will verify that later today. Also, the interaction with 
the new editheader extension needs attention.

Regards,

Stephan.
