It's a problem because Google IPs are white listed by default on my 
system, and it could cause a problem blacklisting a Google server.

I've received numerous messages over the last few days.  I've tried 
sending big cos like Google and Yahoo complaints about spam in the 
past.  They invariably send back denying the messages came from their 
servers.  The following is Google, isn't it?  I could be spacing it 
because it's early here in California.

smtp-out3.google.com (smtp-out3.google.com [216.239.45.15])

Thanks.
