[Greylist-users] Whitelisting Airline domains

[Jim Wright]

Today a user of mine was waiting on an airline confirmation mail from 
Delta, and the greylisting delayed this more than she would have 
preferred.  I already had SouthWest Airlines defined (it looks like 
most whitelists include them), and just added Delta's 205.174.22 
server, but I'm wondering if anyone out there might happen to have IP's 
for any other airlines so that I can avoid this particular problem in 
the future.

Thanks!
