While the same email sent to yahoo Mail was opened 20% of the time. Among them, the open rate of emails sent to Gmail is less than 1%, and most of them are in the spam folder. We have counted the data of emails sent by SES since 2020. We found some problems when using AWS SES service and we shall be grateful if you could help us solve the following problems together: I just can't find docs on the ALB side to validate. It does look like Cloudfront specifically does allow this sort of non-standard request to the origin: so my guess is that it all is intentionally supported. And DNS for `` resolves to the CF distribution. For this example, one CF distribution would be set up with `` as its CNAME with a valid ACM Cert (attached to CF but not ALB), and with `` as its custom origin domain name, and configured to forward the Host header. The different applications this ALB will be sitting behind are all on Cloudfront. It does talk about "smart certificate selection" for SNI, but it does not go on to say anything about the routing rule evaluation for host headers caring or not caring about matching. But it seems AWS ALB will allow this out of the box? I can't find in the () anything specifically mentioning this.

This I know is non-standard, but I am able to successfully make requests to my target group by forcing the hostname in the SNI ClientHello to be `` and not match the Host header in the actual HTTP request ``.įor example, this would succeed: (note: I don't even need to pass `-k` to ignore SSL errors, because the TLS connection is valid for the `` hostname)ĪFAIK most other servers will reject a request if the SNI host does not match the HTTP Host header, or at least require some manual settings override to allow it. DNS for `` does _not_ resolve to the ALB. I do _not_ have an ACM Cert covering this domain attached to the ALB. I then add a single additional routing rule: if Host header matches `` then forward to some target group. The default action is to return a fixed 503 response. Right now, it has 1 default ACM Cert attached, for example for a domain ``. I have a shared internet-facing ALB that I am using for several unrelated applications. I have a particular setup that is currently working, but I am trying to find docs or something to make sure it is definitely supported and not just something that might get fixed later on.
