Leverage DKIM Authentication-Results #4

Closed pinkforest closed 1 month ago

pinkforest commented 1 month ago

Modern e-mail infrastructure implements Authentication-Results header

This header includes the passage on what the incoming e-mail server thinks about the status of Domainkeys Identified Mail (DKIM) Signatures verification.

We can use this status to create conditional e-mail pipelines.

What we can also do w/o copying is "move" e-mails between IMAP folders according to it's authenticated status.

I've published parser and verifier library msg-auth-status that I can leverage for this.

This would be good for SDF. Can you check if this compiles to WASI?

If connectors would be going wasi we would need to switch from async-std that is used by all connectors .. I think

I also have no_std protocol implementations that allow operating in both host io_uring & wasm guest as sans-io if needed
