So I followed the instructions at https://docs.aws.amazon.com/ses/latest/dg/send-email-exim.html
But I can't send any outgoing mail. It times out, and gets bounced back to me. I'm out of the SES sandbox, and I'm receiving e-mails just fine. It's just sending the e-mails.
Is something set up differently with TinyCP's Exim that I need to take into account?
I'm able to send out a test e-mail just fine using this method - https://docs.aws.amazon.com/ses/latest/dg/send-email-smtp-client-command-line.html but when I use Exim or Roundcube, it has issues.
