Is there any reason reason="invalid (public key: not available)" is declared as "error" to fail t_dkim_invalid
1.0 T_DKIM_INVALID DKIM-Signature header exists but is not valid This is published a neutral so should not be considered invalid This only occurs since upgrade 3.4.0 - 3.4.1, no changed made by the sender - its a govt dept, who doesnt change things at all let alone in middle of weekend. Be a shame to have to score that 0 simply because the code over reacts.
