Well, you did some research already, only thing I can think of ...

If possible connect the mail server directly to the router and ignore any external firewall.
Dunno about your network layout, but if it's router > control in DMZ > connect then you could try out router (with firewall and port mapping) > connect for securitry reasons.

Also turn on all DEBUG protocols from connect.

I don't believe it's a problem with kerio itself, more a routing or blocking problem. otherwise the server wouldn't be reachable locally.

Could also be some kind of route problem or network hiccup. Maybe some ip address conflicts?
