syncing mailboxes with dsync after switchover

[Sergey Schwartz]

Gentlemen,

I guess my mistake was to use *-R* option, that works similar to *-1* 
and your messages can get lost.

-R     Do  a  reverse  sync.  Normally, messages would be pushed from 
the local system to the destination (remote). This option reverses the 
flow, and will
               instead pull messages from the remote to the local storage.

doesn't say clearly that it works like a backup mode and data can be lost
