Just thought I'd point out that if you want to use ssh, it should be installed
on both ends:
"doveadm(u...@abc.net): Fatal: execvp(ssh) failed: No such file or directory"
If you don't want to, or can't install ssh, you can also use doveadm server:
service doveadm {
inet_listener {
port = 12534
}
}
doveadm_port = 12534
doveadm_password = secretpass
Then you can use tcp:otherhost:12534 as target/source.
