Philipp,

I already tried explicitly specifying port, it does not make any difference. I tried quite many 'obvious' (to put it this way) configuration changes and tried changing many things in setup, but it would be too much to list all of them in a post.

Basically, I was hoping that someone would know what exactly triggers this behavior, so I could fix it.

At this point in time, I would like to see whether I can make this work with 2.2.9 that comes with Ubuntu 14.04, to avoid having to compile anything from sources (for easier maintenance, later on, since I probably won't be the one maintaining this).

I am also not sure whether there is a reliable (semi-official?) PPA with latest Dovecot. I saw this one ( https://launchpad.net/~mamarley/+archive/ubuntu/updates ) but I am not sure whether I can rely on it not breaking anything at some point.

Thanks.

would you try: mail_replica = tcp:192.168.1.100:12345 which works for me.

check for firewall settings (both ways) anyway - and I can only advise to go for 2.2.16; there have been numerous fixes after 2.2.9 to the whole dsync/replica parts.
