If you're receiving lots of spam, there's a few simple tricks you can do to decrease the amount of spam in your inbox.
Our filters, by design, are set to protect you against serious spam. However, the filters have been set to not be "too aggressive", as this can cause emails to be marked as spam incorrectly.
The best way to protect you against spam, is to build strong intelligence about what really is spam.
To help train the filters:
To train our spam filtering system, you can simply move emails to your 'Junk' folder. This will automatically upload the email headers to the spam filter and it will analyse future emails for similar patterns. This is a method known as Bayesian learning. Our spam daemon, rspamd, is highly popular for this specific learning technique.
Every email that enters/leaves our servers will generate a score in the spam filtering system. The lower the score, the better. You can help train the filter to score these emails more accurately by sending them to your Junk folder.
Alternatively, in your Quarantine interface, you can select emails and click "Learn as spam and delete" - this has the same effect. Within the Quarantine interface, you can see the specific score and breakdown of the scores per email.
Change the filtering thresholds for your account:
If you want to change the way that the system scores emails sent to you specifically, you can log in to your email control panel at https://mail.zarro.co.uk and click 'System', 'User Settings' and then 'Spam filter'. You can adjust the dials. The lower you set the dials, the less spam you'll receive. Be careful not to set them too low, else you will block emails unintentionally. The default scores are optimised for most users, so only change them if you find yourself receiving more spam than desired.
