Yup! SpamHaus and GoDaddy are conspiring against the likes of those who likes to put their videophone IP address in our email signatures.
My email signature looks something like this:
--I was having trouble emailing my own clients -- two of them in fact -- was getting bounce back emails looking like this:
phone: 800.900.1000 | http://mywebsite.com | video phone: callhome.homeip.net
This is an automatically generated Delivery Status NotificationUpon further investigation, I found they were both using GoDaddy as their email host.
Delivery to the following recipient failed permanently:
Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 16): 554 The message was rejected because it contains
prohibited virus or spam content
Called GoDaddy... sent the blocked emails to their tech support guy, and lo and behold, the flag was the dynamic DNS address I had set up for my video phone (which is H.323 based by the way). Asked them what vendor they use for spam filtering -- SpamHaus.org.
So -- those with video phones and dynamic DNS -- be WARNED! They're out to getcha!
OK, OK, jokes aside -- I changed my signature and this change works (changing dot to [dot]):
phone: 800.900.1000 | http://mywebsite.com | video phone: callhome[dot]homeip[dot]net
There ya see it!
