The output showed debug output from the local dsync, but not from the remote. I think you'll see that if you do:

sudo -u vpopmail doveadm sync -u user1 at b -f ssh mx2.a doveadm -Dv dsync-server -u user1 at b

Also it's possible that in v2.1.1 there was some bug related to this.. You could try the latest nightly snapshot that has several fixes related to dsync: http://www.dovecot.org/nightly/

doveadm sync should be run before the destination Maildir exists at all. If vpopmail creates that, I guess it would just have to be deleted manually..

The GUID is generated the first time it's used, which normally means when you run dsync for the first time. Alternatively you can also use doveadm to ask for the mailbox's GUID and it gets generated:

doveadm mailbox status -u user at domain guid '*'

Running rsync after this is done also copies the GUID (it's stored in dovecot-uidlist).
