Personal Spam Filter

You can train your personal spam filter when you mark an email as spam. The next email from the same sender will be automatically moved to the spam folder.

When you first use your mail.com mailbox, your personal spam filter is still empty. Your personal spam filter is not trained until you click Spam or Not Spam to move incorrectly saved emails into the Spam folder or the Inbox folder. The same occurs if you move emails to the Spam folder or the Inbox folder by drag & drop or using the Move button. The spam filter remembers the following properties:

The address of the email's sender
The text pattern of the email

If you receive another email from the same sender, or an email with a similar text pattern from another sender, the email is automatically saved in the appropriate folder.

To ensure that your personal spam filter functions perfectly, you have to move emails incorrectly saved as spam, and undetected spam mails to the correct folder. If certain emails are saved in the wrong folder repeatedly, you can reset the spam filter in the Spam Protection settings to solve this problem.

How the text pattern component works

The text pattern component in your personal spam filter works with wordlists that are created from the emails you have selected as Spam or Not Spam. The filter determines the frequency with which words occur in the selected emails and creates a custom model for your mailbox. This model is used together with the probability methods to classify new emails as wanted or unwanted. Put simply: the more often a word occurs in wanted or unwanted emails, the more it is weighted during filtering.

Incorrectly classified emails

If your emails are classified incorrectly, remember that your filter rules are processed before your personal spam filter. Examples:

You have set up a filter rule which always saves emails from the sender john.doe@mail.com to the Spam folder. If you mark an email from john.doe@mail.com as Not Spam, emails from this sender are still moved to the Spam folder.
You have set up a filter rule which always moves the emails from sender john.doe@mail.com to the Inbox folder. If you mark an email from john.doe@mail.com as Spam, emails from this sender are still saved in the Inbox folder.

Your whitelist is also processed before the spam entries in your personal spam filter. Example:

The sender john.doe@mail.com is on your whitelist. If you mark an email from john.doe@mail.com as Spam, emails from this sender are still saved in the Inbox folder.

Using POP3 or IMAP

If you use POP3 to access your email, you should set your email client or your mail app to leave copies of the emails in the mail.com mailbox. You can then log in at mail.com and move incorrectly classified emails to the right folder using the web interface.

If you access your emails using IMAP, you can move incorrectly classified emails to the right folder directly in your email client or your mail app. Your personal spam filter remembers the text pattern of the email, but not the sender address. To train the spam filter optimally, you must log in at mail.com and use the web interface to move the incorrectly classified emails to the right folder.
