Yahoo is not your only problem, if you look at http://moensted.dk/spam/?addr=216.220.40.247 you will notice that several DNSBL lists that IP address. No-more-fun believes it to be a "Direct spam source" and ArixDictStale says it has performed active dictionary attacks within the last 3 months.

If you want to positively check whether you are an open relay, I would recommend testing through ORDB at http://ordb.org/submit/

Today our email forwarders started getting this from yahoo.com mail handlers:

553 Mail from 216.220.40.247 not allowed - VS99-IP1 deferred - see help.yahoo.com/help/us/mail/defer/defer-02.html (#5.7.1) Connection closed by foreign host.

Which when you go look at that page basically tells you you're probably an open relay (which we're not), etc.

Can any mail admins at Yahoo contact me offlist, or post what the restrictions are or at what levels this will kick in?
