Howdy,
I'm not sure what the "TLS not available due to local problem" error is. You may want to look in your mail logs, /var/log/maillog or /var/log/mail.log, in order to get more details.

That just means that greylisting is active on your server.
That can be enabled or disabled in Email Messages -> Email Greylisting. We recommend using that though, as it's a great way to reduce spam.
