Ha Anh Vu commented on JAMES-3306: ---------------------------------- Hi [~btellier], I'm a GSOC student interested in the Apache James project. I'm still studying the ADR, merged PRs, issues... of the project. In the meantime, I'm looking for beginner-friendly issues to fix to better understand the codebase. Since this issue seems short-term and not too big and also somewhat related to the GSOC project, can I give it a shot to better understand the codebase?
