Can someone tell by looking at this log snippet what may be going on here?

May 20 15:08:37 blah courierd: newmsg,id=00056BEF.40AD2C65.00002C8D: dns; localhost (localhost [127.0.0.1]) May 20 15:08:37 blah courierd: started,id=00056BEF.40AD2C65.00002C8D,from=<>,module=esmtp,host=ms18.hin et.net,addr=<8ac...@ms18.hinet.net> May 20 15:08:37 blah courierd: Waiting. shutdown time=none, wakeup time=Thu May 20 15:13:33 2004, queuedelivering=9, inprogress=8

To me it looks like a message is coming from localhost only.....my domain is NOT hinet.net..

What is going on here and what would be recommended?

Here also is my default smtpaccess file:

localhost allow,RELAYCLIENT ## By default, enable relaying for localhost.

24.17.224.197 allow,RELAYCLIENT

# Also, enable relaying for 10.0.0.0/8 and 192.168.0.0/16

10 allow,RELAYCLIENT 192.168 allow,RELAYCLIENT

# Use the following entry to deny connections from bad IP addresses # # 192.168.5 deny 168.95 deny 219.91 deny 210.59 deny

the three IPs that I have listed as deny are ones I *think* are part of this wierd domain...but they are still coming through so I suspect something else is going on.

Any help would be appreciated..

Thanks
