The user can also define a list of languages which they want to receive mail in, and SpamAssassin then assigns a higher score to all mails that appear to be written in another language. This can be very useful to users receiving a lot of foreign spam but never actually corresponding with people in that language.

With a spam threshold of 5 (default as of SpamAssassin version 2.55), several other tests would usually have to fail for the mail to be classified as spam.

For instance, graphic-only spam messages have no text to compare to therefore checking the sender's originating mailserver and included links against various databases of known e-mail abusers enables the prevention of unnecessary or non-personal mail getting through to the end user.
