mirror getting: access denied to pgsql-ftp on rsync.postgresql.org

Hi,
We have a box that has been set up as a mirror for postgresql for already a few years.

I was just checking and found out that our rsync script hasn't been working for already a while

Starting Sync to rsync.postgresql.org at Mon Sep 14 16:15:02 CEST 2009
Logfile in /home/mirror/log/pgsql-ftp-2009-09-14--16-15.log
@ERROR: access denied to pgsql-ftp from mirrorhost.kangaroot.net (62.213.203.174)
rsync error: error starting client-server protocol (code 5) at
main.c(1383) [receiver=2.6.9]

We're getting these errors consistently and from looking quickly, it seems they started somewhere around january this year.

This is the command we use:
/usr/bin/rsync --address=62.213.203.174 -avz --delete rsync.postgresql.org::pgsql-ftp/* /home/mirror/pub/postgresql

How can we resolve this?

Btw, I couldn't find a "documentation for mirrors" page.
I did find http://archives.postgresql.org/pgsql-www/2005-05/msg00049.php, but I'm not aware of a *.postgresql.org dns pointing to us

Thanks,
Dieter
