SpamAssassin: Global Subject Rewrite

Select this option to prefix the Subject header with information from the X-Spam-Subject header and omit the X-Spam-Subject header.

SpamAssassin™ is a program that blocks and detects spam. SpamAssassin examines the content of an email message and assigns the message an overall score. SpamAssassin bases the score on the number of spam-related traits that it finds in the message. If the message’s score exceeds a predefined limit, SpamAssasin discards the message.For more information, visit the SpamAssassin documentation.

Select this option to define the spam score that is used by SpamAssassin to bounce incoming messages.

Enter a positive number, a negative number, or a number with a single decimal in the text box. You can also choose the default setting, which is not to use this option.
