Spam protection Aggressive setting blocks legitimate emails!
Because of the phishing emails I have been receiving fraudulently claiming to be from Fastmail support I created a ticket and Fastmail support changed my Spam Protection from Normal to Aggressive. I created an Uber account but did not receive the confirmation email either in my Inbox or my Spam folder. I changed the spam protection from Aggressive to Basic and requested Uber to resend the confirmation email. I received it right away in my Inbox.
My concern is that when I have my spam protection set to Aggressive that legitimate emails labeled as spam do not land in my Spam folder and are not even delivered! I cannot afford to have legitimate emails labeled as spam and not even delivered so I can read them. Why did this happen and should it have happened? Has anyone else experienced this? I cannot afford to have legitimate emails blocked from view so I guess I will have to move the spam protection back to Normal. |

I'm surprised that the Uber message had a spam score of 10 or greater, which is the discard threshold for the Aggressive setting. If you expect to receive messages with such high spam scores, you should never use the Aggressive spam setting unless you know that all messages you receive are whitelisted (sent from people in your online Address Book). Look at the Spam/Virus Protection page description of Aggressive protection:

One thing Bill does not mention is checking whether you are using a personal Bayes database. Generally speaking, if you are using settings that train your database effectively, it will be better to be using a personal Bayes database as it will learn the characteristics of the spam you are receiving and react accordingly. It can, however, happen that an improperly trained personal Bayes database can actually lead to worse results than the default global Bayes database. It is worth checking which database is in use and considering whether you are receiving the expected results.

That's an excellent point, BritTim! The things which in the long term I find to be most useful in managing spam are:
