Re: DKIM causing bounces


 

Lena,

DKIM signatures don't contain dates.
Actually they do contain a timestamp. In this case t=1531244118; which is GMT: Tuesday, July 10, 2018 5:35:18 PM -- 18 seconds ahead of the Received field, as advertised.

Looking at your message I have t=1531269237; aka GMT: Wednesday, July 11, 2018 12:33:57 AM; and Gmail's Received from Groups.io is Tue, 10 Jul 2018 17:33:38 -0700 (PDT). Nineteen seconds ahead. I doubt Gmail's servers are off, so I'm going to CC support on this one.

Zoho can be faulted for that confusing minus sign though ("-18 seconds in the future"). And for one of the more picayune reasons to bounce a message I've heard of. But a sanity check is a sanity check I suppose.
I wonder if they have any tolerance on that - would one second in the future also cause a bounce?

Someone has a time server issue!  How to figure out which one?
