I did use 'mirror', I just forgot to paste it.

JFTR:
	vmail> dovecot --version
	20120303 (1002733ca266+)

	vmail> dsync -v -f -u test mirror ssh vmail at remote-host.tld dsync -v -f -u test
	dsync-local(test): Error: remote: dsync: illegal option -- f
	doveadm dsync-server [-u <user>|-A] [-S <socket_path>] 
	dsync-local(test): Error: read() from worker server failed: EOF

If I do omit the remote '-f' the old syntax is being accepted. Thanks for fixing that.

Ah, yes. That was my mistake, sorry.

	vmail> doveadm sync -f -u test ssh vmail at remote-host.tld
	dsync-local(test): Error: remote: dsync-server: Command not found.

Users are virtual ones at both mail servers, and vmail is the only system user to run ssh. Thus I 
can't test user suggestion. But it's ok to add a 'doveadm dsync-server -u test'.

Now, I will stick to 2.1.x because syncing is done without loss of mails (after 10 days of testing).
The only inconvenience remaining is reappearing of deleted and "undeletable" mail. But it seems that 
I'm the only one reporting that. How could I help to debug this issue?
