Re: ipv6 problem connecting to comcast.net "comcast ESMTP server not available&q

I'm having the same problem from 2001:19f0:5c00:8a22::64 even though rDNS works OK.  Am I blacklisted too?  Can I please be un-blacklisted?  I swear I'm not a spammer!  Thanks.

I'll take a look and see what I can find.  I'll get back to you shortly.
