> 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
