Seems my email server is under attack, but I have set to not open relay, not sure what else I can check

I see email log like below quite a lot, but I have no idea what is it? it doesn't look like a smtp from clients, is it from outside to the server? but the liaomeng.com is not in my email domains.

Your Kerio server is trying to send a mail out to a recipient at liaomeng.com. This server can't be reached so it tries several times.

Have a look at the queue to find out who is trying to send that mail.
