Yes, mail is replicated in existing folders, but new subfolders don't 
get replicated.

The config I listed was on the vmail (master) side, indeed. Config on 
the vmail1 (replicated) side is identical except the replication parts. 
I list it at the end of this mail for your reference.

Yes. Everything is fine: 317 identical accounts on each side (read from 
replicated LDAP).

Yes: vmail.example.com vs vmail1.example.com

OK, I ran the command:

doveadm -Dv sync -u imaptester ssh -l root vmail1.example.com doveadm 
dsync-server -u imaptester

The output is similar. Still no subfolder sync (but individual messages 
on existing subfolders get sync'ed):

...

recv_state=mailbox send_state=mailbox

dsync-local(imaptester): Debug: brain M: out state=sync_mails changed=1
dsync-local(imaptester): Debug: brain M: in state=sync_mails
...

Please suggest any other ideas!

Thanks,
Nick
