It's not that easy since actual messaging of these "initial sync"
thingies was added later. After looking into the logs it seems it has to
do with QRESYNC handling; I'm using Dovecot 1.2 and it should support
QRESYNC, hence I don't understand why I'm seeing so many "initial
syncs". It could be because my connection drops frequently (as I've
said, reception is terrible).
