Hmm.  Maybe the problem is this:

$ nslookup -q=mx postgresql.org
Server:  localhost
Address:  127.0.0.1

Non-authoritative answer:
postgresql.org  preference = 0, mail exchanger = mail.postgresql.org
postgresql.org  preference = 20, mail exchanger = mail1.hub.org
postgresql.org  preference = 20, mail exchanger = mailserv.hub.org

Authoritative answers can be found from:
postgresql.org  nameserver = NS.TRENDS.CA
postgresql.org  nameserver = NS.hub.org

mail.postgresql.org     internet address = 216.126.85.28
mail1.hub.org   internet address = 216.126.85.1
mailserv.hub.org        internet address = 216.126.84.253
NS.TRENDS.CA    internet address = 209.47.148.2
NS.hub.org      internet address = 216.126.84.1

From out here, the primary mail acceptor for 'postgresql.org' shows
as mail.postgresql.org = 216.126.85.28.  Should we be preferring
216.126.84.28 instead?  It sure looks like there's an unnecessary
hop happening inside hub.org.
