useful to see what has to be done on each folder and guess when
the transfer will end (ETA).
R. Add also --nocheckmessageexists
Since transfer can be long on a huge mailbox imapsync checks
a message exist before copying it, but it takes time and
cpu on the host1 server.
--nocheckmessageexists is on by default since release 1.520
R. Add also --noexpungeaftereach if you use --delete but be warn
that an interrupted transfer can loose messages on host2 in a
second run if you use a combination like
imapsync ... --delete --noexpunge --noexpungeaftereach --expunge2
