Hi, There seems to be something wrong with the dns config for gplsucks.org. The reverse lookup for 63.227.213.93 returns work.gplsucks.org. But when I try resolve work.gplsucks.org it fails. mail.gplsucks.org does resolve to the above IP address which I assume is correct. You should just get whomever is hosting your reverse DNS to change work.gplsucks.org to mail.gplsucks.org. Whether this will fix your problem I don't know.

That is the correct IP but why would the > IP show up as the hostname? I'm not sure I understand your question. When you make a connection to a remote host, the packets that the hosts exchange, contains the source and destination IP addresses only, no host names. For the remote mail server to find out the host name for that IP it needs to be able to do a reverse dns lookup. It seems that in this case it could not determine what the host name for this IP address was. This is one of the measures employed to help minimize spamming. > > On Mon, 4 Sep 2000, Willem Brown wrote: > > > Hi, > > > > Does it happen all the time or was just this once?
