This cannot be considered a SpamAssassin bug unless you have some other trustworthy DKIM signature verifier which validates a signed message that SA deems invalid. 2. Mail systems routinely make harmless changes to email which break DKIM signatures. This can include an encoding change that may be necessary to transport a binary attachment over Internet email.=20 3. It is literally impossible to diagnose your problem without a specific UNMODIFIED complete example.=20 4. This is the sort of probable non-bug problem which should be better addressed on the SpamAssassin Users mailing list.=20 5. Redefining & rescoring DKIM_INVALID as you have done is deeply unwise. T= he definition in the default ruleset only hits on signed messages whose signat= ure does not validate and it is scored at 0.1 because of the common problem of = DKIM signatures breaking in transit. Marking every unsigned email and every sign= ed email with a broken signature as spam (i.e. with a 5.0 score as your rule d= oes) is a choice to intentionally mislabel mail. --=20 You are receiving this mail because: You are the assignee for the bug.=
