>                 URL: https://issues.apache.org/jira/browse/COMDEV-259
>             Project: Community Development
>          Issue Type: Project
>          Components: GSoC/Mentoring ideas
>            Reporter: Kevin A. McGrail
>            Priority: Major
> SpamAssassin is a computationally expensive process to run.  It is more 
> costly as emails get larger.
> So SA has safety valves to prevent excessive usage and DoS by limiting the 
> maximum size of emails processed.
> Spammers sometimes try and get around this with short messages and large 
> attachments to bypass scanning.
> There are techniques that exist to truncate emails that are sometimes less 
> effective so this task would be to identify better techniques in order such 
> as:
> For example:
>  * remove attachments for scanning
>  * Check size and scan if small enough
>  * Truncate the message after closing any open tags
>  * scan
