Trying the dsync replication for the first time, and I am confused as

replication meant to replicate mails immediately upon submission to
lmtp/lda and on change via IMAP/POP3,

Yes.

or is the replication_full_sync_interval the only configurable for
determining when the replication will occur?

No.

Timo, correct me if I am mistaken, but that keyword will tell the 
replication system when to apply a "dsync -f" aka running in "full 
sync mode" at latest.

Maybe a better question is there any documentation on dsync replication
(could not find any)?

Thanks for the information Michael.  I must be configuring this 
incorrectly as the replication is not occurring when messages are being 
delivered via LMTP in my setup.  When I restart dovecot the messages are 
synced immediately, but not on delivery.

Here is my config:

# 2.2.rc2: /usr/local/etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-279.22.1.el6.x86_64 x86_64 CentOS release 6.3 (Final)
