This is still happening after a reboot, Fedora 28. Restarting dovecot
fixes the problem. Does anyone know if it could be related to this bug
report? *https://bugzilla.redhat.com/show_bug.cgi?id=103401#c130 * and
suggested work around to add ports to
/proc/sys/net/ipv4/ip_local_reserved_ports?
Yes.

If you have nfs clients running, they often step on ports in that
range. Alternate work-around is setting sunrpc.min_resvport = 994 in
/etc/sysctl.d/99-whatever.conf
Better would be to move away from port-based "security" (not actually
secure at all) . Either switch to samba or nfs v4
