Hi, Recently purchased maillwizz, seems legit so far. Problem is I've been trying to verify a Delivery Server using Amazon SES. What I have done so far: 1. Validated SES account. 2. Verified domains. 3. Created an user in IAM manager. 4. Filled up fields in Mailwizz. But everytime I try to verify it, it says something like: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details. The Canonical String for this request should have been 'POST / host:email.us-west-2.amazonaws.com x-amz-date:20170614T005930Z host;x-amz-date c9c1ad63c7ab57b4c1ce8b97b80fa7b99dd7651b4f2b65844ceb1cef96c4155a' The String-to-Sign should have been 'AWS4-HMAC-SHA256 20170614T005930Z 20170614/us-west-2/ses/aws4_request 302a80abdda04718b57eedbae0be62e106221e79c11f9ddc2afedd9a21568589' I've tried everything, googl'ed everywhere. Any ideas? Thanks.
