Is it possible to use DSYNC between dovecot 1.2.15 and 2.1.7 servers ?

Precisely replicate a dovecot 1.2.15 server to a 2.1.7 server ?

Short answer is, don't do it.

Dsync, prior to 2.2 (where it was completely rewritten), was unreliable and prone to breakage.

If you want to use dsync reliably, both need to be running 2.2.
