We have a Drupal system running on acquia platform and was using smtp for the mail connection. Previously we were using gmail account to sent the mail and was working fine. But now as per the requirement from the client side, we are trying to connect with AWS SES mail system from Drupal using SMTP. But unfortunately that didn't work.
We had enabled the smtp mode on the AWS SES and added an email on the verified mail list. Also created password for smtp. Then we used this credentials in Drupal smtp config form. But mail sending is not working.
The Drupal side, it is showing the connect authentication issue. And on the AWS SES side, we are seeing the bounce mail reports. So we are aware that the connection is not blocked anywhere.
Please find the details that we used in Drupal as part of smtp configuration:
Any help is appreciated!!
Thanks.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
I think some domaine name as host don't work for some reason if you put an ip address instead it works ...
We're having this issue on platformsh for example using the variabe Platfrom_smpt_host which return a long domaine name but if we use the ip address it works fine...
