There are two problems here.
The first one is with the mailer configuration at postgresql.org.
postgresql.org lists to MX records. The first is for
mail.postgresql.org, the second is for ftp.postgresql.org.
Unfortunately, ftp.postgresql.org rejects mail for the postgresql.org
domain, reporting ``Relaying denied''. This is definitely bad. If
postgresql.org is going to have a secondary MX, the secondary system
must accept mail for postgresql.org. I am CC'ing Marc Fournier think
I think he is responsible for the postgresql.org mail system.
The second problem may be caused by the fact that there is a problem
with the minnesota.com domain.
The root name servers report that the name servers for minnesota.com
are ns01.minnesota.com and ns02.minnesota.com. ns02.minnesota.com
appears to be down at the moment. ns01.minnesota.com reports an
additional name server: ns1.uswest.net. That ns1.uswest.net server is
lame: it gives nonauthoritative replies for minnesota.com.
Whoever is responsible for the minnesota.com name servers should fix
them to not report ns1.uswest.net as an authoritative name server for
minnesota.com. Alternatively, get ns1.uswest.net to actually be
authoritative.
