I am using the smtp amazon..

When valid SMTP server or test campaign DKIM works in gmail.

But when sending the campaign DKIM failure.

Code:
dkim=fail header.i=@amazonses.com;
spf=pass (google.com: domain of 0101015490ecddce-c5a70e8b-020c-4f43-8fd0-192e91a488d4-000000@us-west-2.amazonses.com designates 54.240.27.33 as permitted sender) smtp.mailfrom=0101015490ecddce-c5a70e8b-020c-4f43-8fd0-192e91a488d4-000000@us-west-2.amazonses.com

I can see that "Feedback-ID" has been used twice in the signature (may be one from MW and the other from SES). This header is not included when doing a template test. That may be why it's passing while testing. If that's the case, probably DKIM processor at SES is not handling this external header well.

Try with DKIM in one line without spaces or lines breaks.
(mwz generates it with spaces and line breaks, and some services may get a hick-up from this, even though they should not)

But when I add the server works . ( When validates the server) .

Only when you send the campaign takes place this problem.

Maybe they really strip some header info, or do you see the DKIM signature when the mail arrives?

Yes I see. When the registration validation e- mail server gets correct DKIM .


But when sending a campaign comes invalid..

Yes . Is it working DKIM to validate a server for example.

But when the system sends the campaigns appear as invalid in gmail.
