Hi,sieve vacation replies are rejected by gmail with a "555 5.5.2 Syntax error". The return path is set to "<>", I think this is why this error is triggered by gmail.
The rest of the vacation message seems ok.
I'm using dovecot 1.1.11 (waiting for final 1.2 to upgrade) , delivering with "/usr/lib/dovecot/deliver -d em...@domain"
