Amazon SES SSL Hostname
I use Amazon SES 99% of the time to relay emails from online platforms and WordPress sites; with WordPress in particular I have been using the Easy Wp SMTP plugin.
Most of the time it is never a problem using the standard SMTP details you are provided with from Amazon SES, but in some cases when selecting SSL/TLS as the type of encryption it always fails validation when sending a test email.
To get around this you can add
ssl:// to the start of the hostname, and leave the type of encryption set to none.
And thats it; entering SMTP details that way has never failed validation.
