Plusnet redirects fail

[#1]

PlusNet redirect does none of the modern requirements:

- no SRS
- no ARC
- no DKIM preservation guarantees
- no envelope rewriting

So as the ecosystem tightens, PlusNet redirects fail more and more often.

[#2]

Are you referring to emails serviced by Plusnet, or after migration to Greenby?

Or both?!

[#3]

I don't believe I've been migrated yet, how would I know?
But your answer suggests the platforms may handle redirects differently.

[#4]

Me too. This was after migration.
