I have computers at two different locations and one computer running dovecot at each place. I sync my emails between these two servers using ssh and I haven't had any problems with this lately until I upgraded dovecot recently.
I now get the following error at location "alfa" when trying to sync with dovecot at location "delta"

This is a problem that was introduced in 2.3.11 and fixed in 2.3.17.
Updating would be better, but as a workaround you can move the ssl_key line to a separate config file, make it only readable by root, and use e.g.
!include_try /etc/dovecot/ssl-keys.conf
to pull it in.
