Replication Advice Needed

[Asai]

I successfully set up Dovecot replication, having 2 servers syncing with 
each other.  While I had both servers in the same room on a Gigabit 
network, they were syncing fine.  But I took one to another location, 
and syncing was turned off for about 2 weeks.  Now I've turned both back 
on, they're sort of syncing, but not really.  The one remote server is 
not populating emails into various folders and it really should be 
cranking to sync those emails.

Do anyone have any insights on how we could troubleshoot this?
