Summary: SpamAssassin Size Check Improvements
Key: COMDEV-259
URL: https://issues.apache.org/jira/browse/COMDEV-259
Project: Community Development
Issue Type: Project
Components: GSoC/Mentoring ideas
Reporter: Kevin A. McGrail
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
