Anti-spam analysis

Click on the 'Anti-spam analysis' button at the bottom of the preview window to launch an anti-spam analysis of the current message.

The anti-spam analysis gets your message, analyses it and shows you an analyse score. The higher the score is, the more chances you have to get your message flagged as a spam.

There are three levels of score:

The green means your email is not likely to be filtered or blocked.
The yellow means your email may be filtered or blocked.
The red means your email is likely to be filtered or blocked.

Note :

The anti-spam analysis is made by the powerful Apache SpamAssassin project.

You may consider the analysis result as an heuristic advice more than a reality.

Indeed, your message may be flagged as a spam in the receiver's outbox even if the anti-spam analysis result was green because:

The server you are using to send emails is blacklisted.
The server you are using to send emails is not correctly configured.
The settings of the receiver's mail reader or mail provider are more sensitive than the default settings of SpamAssassin.
