1. Has MSN unilatarally and secretly "innovated" new mail domains?
MSN's mail servers, or their DNSs, or both, are screwed up, invalidating
@msn.com, now replaced with @mail.msn.com? And we're suppposed to go
modify our address books and tell our clients, bitchin at us for
undelivered mail, how to get their mail delivered to MSN's variable addresses?
So, to what ip do our mail servers send for [EMAIL PROTECTED] :
# dig mail.msn.com mx
; <<>> DiG 8.2 <<>> mail.msn.com mx
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 4
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0
;; QUERY SECTION:
;; mail.msn.com, type = MX, class = IN
;; AUTHORITY SECTION:
msn.com. 58M IN SOA dns.cp.msft.net.
msnhst.microsoft.com. (
2000053101 ; serial
30M ; refresh
15M ; retry
11w6d8h ; expiry
1H ) ; minimum
ie, DNS says their is no MX record for mail.msn.com. and...
; <<>> DiG 8.2 <<>> mail.msn.com a
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 4
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0
;; QUERY SECTION:
;; mail.msn.com, type = A, class = IN
;; AUTHORITY SECTION:
msn.com. 34m46s IN SOA dns.cp.msft.net.
msnhst.microsoft.com. (
2000053101 ; serial
30M ; refresh
15M ; retry
11w6d8h ; expiry
1H ) ; minimum
ie, no A rec for the mailhost mail.msn.com.
hmm, no MX and no A for @mail.msn.com, smells just like SPAM. vbg
2. Hotmail's mailer daemon bounces undelivereable msgs back to us using
Hotmail's NUL sender and following RFC, but when our mailer daemons bounce
their undeliverable msgs with our NUL senders, Hothmail violates RFC and
rejects them.
