This not Sieve. There is no envelope part "From.*(... " and redirect 
only accepts one address.

The header test matches against headers of the message itself. The 
envelope test matches against the SMTP envelope.

Check the 'Configurable Limits' section of the INSTALL file (wiki needs 
to be updated):

http://hg.rename-it.nl/dovecot-1.2-sieve/file/0.1.15/INSTALL

So, you can configure sieve_max_redirects according to your needs.
