I'm getting the dreaded 554 hop-count exceeded. msg when sending
emails to an Exchange 5.5 box.
I also get this msg when I telnet into it and attempt to send a msg.
The email domain is marked as <inbound> and it was working fine
I had this exact same thing happen before, and it turned out to be
some weird DNS problem. (if I remember correctly?) The MX records
looked using nslookup, but when I used ns1.cisco.com as the server, it
couldn't see the mx records.
The ISP changed something, and it was back.
I got them to send me the DNS zone, and it looks ok, ns1.cisco.com can
see the mx, I can see them, I can ping to the ip and to the mail
I'm confused as how to proceed? I know the ISP has messed something
up - but I cannot figure out exactly where as everything seems ok as
far as nslookup is concerned?
