[UCIMC-Tech] Help! chambana.net mail server still needs reverse-IP DNS entry!

[Stuart Levy]

The problem I mentioned a few days ago, where the chambana.net mail
server's IP address has no reverse-DNS entry, is still ongoing.   Mail
from active mailing lists is unable to reach many people on those
lists.   Imc-tech people, is anyone hearing this?

Here's the latest example.
