Re: dsync between 2 instances on same machine (but different versions and different DNS hostnames) fails with "doveadm server sent invalid handshake"

For posterity, changing the service specification to use "inet_listener doveadm" worked.

I'm happily synching now. :-)

I really do think the docs could use a *lot* of improvement, both in general and for this topic in particular.

I'd be happy to file some doc bugs, if such things get any attention.

I'd also be happy to work up some suggested doc fixes, but I'd need help with some of the technical details, and it doesn't sound like anyone knowledgeable enough cares enough to give me the time. :-(

LMK if someone out there is willing to work a bit with me to make the docs better...
