G'day Stu,
We just got 40 bounces (550s) from hotmail.com. Nothing's changed
here. We've checked all the usual suspects (dns/mta) but mail is
going everywhere else OK. As usual the bounce-reply is non-specific
and points to a general, vague support page.
Q: If you start getting bounces from a particular mob, what MTA/spam
list checkers to you use to see if you've broken some rule?
Does your outgoing mail server have a reverse DNS PTR record set for its
IP address?
(Note that it doesn't need to match your domain, just so long as its a
hostname that will revert back to the IP.)
You can always check the IP address of your mail servers from
http://www.dnsstuff.com/ - There's a broad ranging SPAM database check
there.
All the best!
Raphael
