DKIM Signature Validation Failing - Relaxed Header Canonicalization and Whitespace
Last updated on JUNE 25, 2018
Applies to:Oracle Communications Messaging Server - Version 8.0.1 and later
Information in this document applies to any platform.
Messages are failing DKIM validation on the inbound MTA.
Header fields containing multiple white spaces are converted to a single white space (passthrough mode enabled).
The Message-ID header folded at start, and as expected, the result is DKIM signature verification failed.
This is going to fail to rewrite.
This should not break signature validation for relaxed header canonicalization, correct?
