A couple of days ago I moved my mail server, and inadvertently mistyped
its name in the reverse DNS. After this, I noticed a message wasn't
making it to the list. Investigation showed:
rcpt to: nanog@nanog.org
450 Client host rejected: cannot find your hostname [83.149.65.1] info
at: http://www.merit.edu/cgi-bin/mn/reversednsinfo
Ok, so far so good. But when I visited the URL mentioned in the
rejection message, I just got a web form saying "Please enter your
e-mail address and select your organization from the list below".
Obviously this is meant to do _something_, but it's entirely unclear
what and why.
After this the page I think should have been referred in the first
place comes up: http://www.merit.edu/mn/support/reversedns.html
There is also a link to a DNS checking tool. However, this tool is
pretty much useless in situations such as the one in which I found
myself, as it doesn't answer the real question: what is the TTL for the
offending DNS information.
