[Evolution] evolution filter export/converter to SIEVE

[Johannes Behr <jbehr zgdv de>]

Hi,

SIEVE is a mail filter language used e.g.
in imap-server to filter message directly
on the server.

Our server supports SIEVE filter and I would 
like to immigrate my evolution filters (~30)
to the server.

Is there a exporter/converter which can
create a SIEVE description from my evolution
filters?

best regards,
  Johannes
