I was hoping to increase awareness of SPF with this email... I guess I have 
succeeded! ;-)

http://spf.pobox.com/. I should've mentioned it earlier.

We can add all of these servers to a domain like "mailrelay.postgresql.org", 
and then declare any server in "mailrelay.postgresql.org" as a valid server 
in the TXT record for postgresql.org. That way, we won't have to have a 
huge TXT record.

My only concetion is when you (scrappy(at)postgresql) go to send mail as 
scrappy(at)postgresql(dot)org, you are sending it through ganymede.hub.org. You'll 
need to either get this domain listed in the SPF record (see above), or 
start sending your email as scrappy(at)postgresql(dot)org through a common server 
with SMTP authentication. The same applies for anyone else who has a 
postgresql.org email account.
