[Mimedefang] Potential for Business mail servers to not have reverse DNS

[Mark van Proctor]

Just wondering what the consensus is in regards to mail servers that do not
have reverse DNS configured.

Is it common for business mail servers to be unconfigured in this way?

I have been watching my logs for a few days and all emails from mail servers
that connect with an IP address that does not reverse DNS map have been
spam.

I'd appreciate any thoughts...
