[root at mail ~]# host -t TXT text "v=spf1 ~all"
[root at mail ~]# host -t TXT text "v=spf1 ip4: 
ip4: ip4: ip4: 
ip4: ip4: ip4: ip4: 
ip4: ?all"

Alternatively - I can recommend using '' as a whitelist 
which will include these already:

[root at mail ~]# host has address

Whatever you do though - don't bypass SpamAssassin for Google IPs unless 
you want a load of spam.  Google's outbounds have been on several 
blacklists recently as they don't seem to be able to keep on top of the 
abuse of their services.

Google mail is a nice target for spammers due to Google's own privacy 
policy stating that they will not disclose the injection IP address 
anywhere in the headers as it allows the spammers and bots to hide 
behind them.
