This topic is also being discussed on the exim-users mail list. I received one email 3 times and summarised the differences between them on that list. One was a few bytes longer than the other two: Differences entirely in the headers: • Envelope From line (first line) the time differs • Delivery-date: time differs • First Received: •• 'from' -- sent by google machine •• 'id' -- differs (this is the id generated by my exim) •• time differs • Second Received: google machine, time, id • ARC-Seal: t=xxx b=xxx differs • ARC-Message-Signature: b=xxx differs • DKIM-Signature: t=xxx x=xxx b=xxx differs • X-Google-DKIM-Signature: t=xxx x=xxx b=xxx differs • X-Gm-Message-State: value differs • X-Gm-Gg: value differs. It is this value that is a different length in one of the email > I do hope that Google gets the problem resolved soon. :) Is there anyone from good reading this ? Which MTAs does it affect, ie other than Exim ? -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.
