Hi Steve,

It's not for me to say whether the service is good/bad/ugly!

However, a true MTA does a DNS domain look-up of the MX records for each email 'to/cc/bcc'. What you are showing is the method to connect to authsmtp's server and not how they handle your request.

Are your requests to authsmtp's server failing?

If that is failing, then the service may be overloaded, poor internet connection, etc. I'll send you a private msg with my email address. I think this is out-of-scope for PM, but I have some ideas on how to help you.

Look for my msg and maybe we can get it working for you.

Regards...Ed
