[Dovecot] Dovecot-1.2 + Sieve + Managesieve on Debian

[Proskurin Kirill]

Hello!

I think about migrate from FreeBSD to Linux because I need DRBD for 
clustering.

I want to use Debian Lenny but run on some problems.

I want near latest Dovecot packages. Native repos are too old. Backports 
seems to don`t have a Sieve&Managesieve support and we need it(am I 
wrong?). Stephan Bosch auto packeges is not for production.

How could I solve this without make own packages?
What Debian folk`s do in this situation?

P.S. I don`t want to use RedHat like OS because I not familiar with it.
