[Dovecot] Maildrop script to sieve

[Raphael Bittencourt S. Costa]

Hi,

I'm working on a system that have about 350K e-mail users and 100k users
that uses maildrop scripts to make filters on their delivery. So,
changing scripts by hand can't be a choice. I  "googled" so much and I
wasn't able to find any script that converts maildrop scripts to sieve.
Does anyone knows where can I find it? 

By the way, does anyone uses dovecot-1.1-beta on a production system
with sieve+maildir+lda?  


Thanks,

Raphael Costa
