Current Progress

We are actively seeking volunteers to contribute in these areas:

  • Bug fixes - Although the basic algorithm is very simple, mail servers are complex and variegated, with lots of special cases. Our primary goal is for the basic feature set to consistently and reliably interoperate with every major mail server.

  • Security auditing - Security vulnerabilities are easily overlooked. Finding and quickly fixing these problems is a crucial priority.

  • Simplification of Installation - The server-side plugin relies on complex interaction between Exim, MySQL, and Perl. Simplifying the installation procedure will encourage other system administrators to give Bumper a try.
