Description
Why ?
Alternatives like Postfix...
- Do not offer a unified view of the mail queue across nodes
- Requires statefull persistent storage
Given Apache James recent push to adopt a distributed mail queue based on Pulsar supporting delays (JAMES-3687), it starts making sense developing tooling for MX related tooling.
I propose myself to mentor a Gsoc on this topic.
Benefits for the student
At the end of this GSOC you will...
- Have a solid understanding of email relaying and associated mechanics
- Understand James modular architecture (mailet/ matcher / routes)
- Have a hands-on expertise in SQL / NoSQL working with technologies like Cassandra, Redis, JPA...
- Identify fix and solve architecture problems.
- Conduct performance tests and develop an operational mindset
Inventory...
James ships a couple of MX related tools within smtp-hooks/mailets in default packages. It would make sense to me to move those as an extension.
James supports today...
checks agains DNS blacklists. `DNSRBLHandler` or `URIRBLHandler` smtp hook for instance. This can be moved as an extension IMO.
We would need a little performance benchmark to document performance implications of activating DNS-RBL.
Finally as quoted by a gitter guy: it would make more sens to have this done as a MailHook rather as a RcptHook as it would avoid doing the same job again and over again for each recipients. See JAMES-3820 .
Grey listing. There's an existing implementation using JDBC as an underlying storage.
Move it as an extension.
Remove JDBC storage, propose 2 storage possibilities: in-memory for single node, REDIS for a distributed topology.
Some work around whitelist mailets? Move it as an extension, propose JPA, Cassandra, and XML configured implementations ? With a route to manage entries in there for JPA + Cassandra ?
I would expect a student to do his own little audit and come up with extra suggestions!
