Hi Brandon,

Does GMail publish a list of its outbound hosts/ranges some place to enable us to whitelist?


_spf.google.com. 300 IN TXT "v=spf1 include:_netblocks.google.com include:_netblocks2.google.com include:_netblocks3.google.com ~all"

It's a lot of ranges, and I'm not sure if Google uses them all for mail today, but they well might tomorrow -- I don't see much point in greylisting mail from Google, other than perhaps to allow for URIBLs to learn of new hosts.
