Hi,
I have been using Acymailing on Joomla to send newsletters for a number of years without any issue. I use Amazon SES for SMTP server and it has been very stable.
I recently received an email from Amazon SES saying they will upgrade TLS to version 1.2 before end of 2023.
From Acymailing configuration, I was using TLS as Secure Method before I received the email below. So I changed the Acymailing configuration to SSL as Secure Method on port 465. I hope this will solve the issue as I am not using TLS any more since then.
Below is an excerpt of the email from Amazon SES:
We have identified TLS 1.0 or TLS 1.1 connections to AWS APIs from your account that must be updated for you to maintain AWS connectivity. Please update your client software as soon as possible to use TLS 1.2 or higher to avoid an availability impact. We recommend considering the time needed to verify your changes in a staging environment before introducing them into production.
We will begin deploying updates to the TLS configuration to a minimum of version TLS 1.2 by September 15, 2023, even if you still have connections using these versions. These deployments will complete by no later than December 31, 2023. This update removes the ability to use TLS versions 1.0 and 1.1 with all AWS APIs in all AWS Regions [1].
Can you confirm my Acymailing will continue to be able to send email over Amazon SES after their TLS upgrade to version 1.2?
Thanks in advance.
