LGTM, thanks. Please also change the comment above the class:

runtime/src/libraries/System.Net.Mail/src/System/Net/Mail/DotAtomReader.cs

Lines 14 to 15 in 35d2780

// or end, but we do allow dots at the end for compatibility with other mail clients. We also allow
// multiple consecutive dots, which would normally be invalid.

And we need to change the docs as well as they explicitly mention allowing double dots:

@ericstj Does this need to be documented as a breaking change? See dotnet/docs#50592.

Yeah it should be. Today, reviewers self-identify, maybe we can get copilot to help in the future

@ManickaP -- did you want to create the doc using the link above?

Is this a braking change? I would not consider it as such. It's just making the implementation follow RFC more closely. But correct me if I'm wrong.

The new code behaves differently from previously documented behavior (is more restrictive). I think that counts as a breaking change (regardless how bad the previous behavior was)
