AT&T Wireless IP Clue

[Steve Rubin <ser () tch org>]

Does anyone have an IP clue contact at AT&T Wireless?  They have some 
sort of filter blocking most (all?) of 69/8 to their SMS email gateway, 
and even the AT&T Wireless NOC can't seem to find the problem 
(800-832-6662, option 6, ticket #1087071).  I was leaning towards 69/8 
bogon filters until I noticed that twice a day for about 30 minutes 
everything works.
