Suggestion for New MX filtering

[Dr. Bonnici]

Aloha from Hawaii,

Thank you for upgrading to the new MX system. I just have one suggestion for improvement. I choose to opt out because the new MX system does not have an option for graymail like SpamAssasin. If I could click on an option that would send me an email with what MX filtered, then, after several weeks, I could evaluate whether or not I should keep it operational. As I have no way of checking if MX is filtering out good emails, I cannot opt in as yet.

Thank you for being there all these years and providing such wonderful service and tech support.

with blessings and gratitude

Aloha!

The MX filtering in place today is very similar to what was in place before albeit with a little less transparency as to what exactly it is up to. The whole point of filtering at this level is to prevent us from having to accept and process a message that is 99.9999% likely to be spam. The kinds of things that it rejects should have a negligible rate of false positives and if it does reject a message the sender would receive a notification. In most cases, there's something the senders' mail server administrator would need to fix in order to resolve the problem as it will most likely affect their deliverability to other destinations as well.

I think you'll be substantially happier with it enabled, but know that you can turn it off if needed.

I have opted out of MX filtering as well, and noticed that the MX upgrade caused the settings I had made previously to be reverted to opt-in, so now I had to go change it again.

The reason I opt out is that when my previous employer began using MX Logic as its filtering service, mail from one of the lists I read was consistently rejected. There was no warning to me until I happened to meet the list owner in person. There was no way I could control this filtering other than to completely disable it for my address.

As an RFC author, my email address has been thoroughly exposed for many years, so I have been using my own procmail filtering that has evolved over that time. It would be fine if the MX filtering could just mark the suspected spam so I could divert it to a spam folder for less-frequent examination, but the complete rejection of false positives is not acceptable to me.
