Hi Michael... I can tell you that 'peel.net' is either a spam or other
non-rfc-compliant, BS site. First hint is when you look at their domain
MX records. For one, they only have ONE MX record (which is NOt a crime
of course), but it looks like this:
peel.net preference = 10, mail exchanger = returns.peel.net
Hmmm, RETURNS.peel.net? Nice hostname since it defines the ONLY type
of mail that anyone might ever want to send to them!
Then, to make sure they never hear your complaint of spam or bounce
messages to other undeliverable BS they send, they do this:
[waa
pokey waa]$ telnet returns.peel.net 25
Trying 199.249.167.26...
telnet: Unable to connect to remote host: Connection timed out
Yeah... THAT's a nice Internetizen... grrr. (hey.... I think I need to
trademark that! Internetizen(tm) ) <grin>
I have been watching this for a while now. There is NO way to send these
poeple bounce messages. I have not had the time, but tomorrow they are
going in my list of sites to simply drop connections from. Not sure yet
if I am going to block them at the PIX firewall, or at my mail server
with ipchains, but one thing is for sure - They won't be bothering my
users any longer, nor will they be bothering me nor my logs files any
longer. :-/
In this case, the issue is not at your end Michael, but unfortunately,
the problem is; in the case of 'peel.net' at least.
The problems with deliveries to msn users that you are seeing is (from
what I have gathered on the qmail support list) a problem with
non-compliant DNS servers serving up the MX records for the msn domain.
A suggested 'band-aide' there was to dig the zone for mx records pick
one, and set up an smptroute. That is point ALL email destined for
msn.com to ONE of their mail servers (by IP address), and watch it work
until msn changes server IPs. :)
Hope this helps.
