Namespace

Assembly

MailFathom.Domain.dll

LocalVerificationNotEstablished(SenderDomain?)

Records that this deployment verified what it could and established nothing.

public static SenderAuthentication LocalVerificationNotEstablished(SenderDomain? fromDomain)

Parameters

fromDomain SenderDomain?

The domain the message displays as its sender, where it wrote a usable one.

Returns

SenderAuthentication

The verdict.

Remarks

A message carrying no signature at all, one whose signature named no usable domain, and one whose published key could not be resolved before the lookup's deadline all reach it. The last is the reason the value has to be distinct from a failure: an unreachable resolver says nothing whatever about the sender, and a verdict that called it a failure would turn this deployment's own network trouble into a statement against somebody's mail.
