[vcf-midatlantic] MIME format

[Jason Howe]

Yes and Google just recently changed something with regards to mail and 
ipv6.  I had to add an ipv6 entry to my SPF record last week on my 
domain because google started bouncing stuff, where my ipv4 only SPF had 
been allowing me to send stuff to people on gmail flawlessly for years.

In the last year or so, when setting up new servers, I've been setting 
up AAAA records and making sure services bind to both 4 and 6 addresses 
-- it's actually quite interesting to see how much traffic actually 
flows over ipv6.
