We had relays.ordb.org listed as one of our blacklist servers. We were
unaware that the service has been dead for about a year and a half. All
of a sudden it listed everyone as being blacklisted. According to the
internet that started around 3pm today. It was their way of ensuring that
everyone stopped querying that service. All outside email to Dekko was
rejected and were told they were on the blacklist at relays.ordb.org.
Attempts to access that server were rejected with Page not found. Googling
relays.ordb.org found the solution. I modified my Domino "Configuration"
(not Server) document, Router/SMTP, Restrictions and Controls, SMTP
Inbound Controls and removed relays.ordb.org from the list of blacklists.
Bounced the servers and everything immediately started working.
See link below if you want more details.
bcc: to my LUG buddies, a friend at IBM/Lotus, and everyone in Dekko's
