Solution:
It looks like the automatic Activation email is not sent exactly the same way as when you use the re-send button on a subscriber’s record. The WP Mail SMTP plug-in doesn’t like the way the automatic Activation email is being sent but has no problem passing on the re-sends.
I found a way to bypass the issue by installing the SMTP Addon plug-in (available from the TNP website but not on the WordPress repository). It provides the same function as the discontinued SMTP options and sends both initial Activation emails and re-sends successfully.

Never mind.
I’m going to uninstall this plug-in and go with another that has better support.

If it can help, I enabled the TNP Log = Debug and I have a set of log files for:
“TNP New subscriber activation: Fails – SMTP Error Could not authenticate”
and another set of logfiles for:
“TNP Resend activation button for that subscriber: OK”
I will be happy to send them if you wish.

Hi,
I’m having the exact same problem. Happens all the time in the exact same sequence.
I ran all of the following tests:
WP Mail SMTP Email Test: OK
TNP System Delivery Diagnostic: OK
TNP Activation Send a test: OK
TNP New subscriber activation: Fails – SMTP Error Could not authenticate
TNP “Resend activation” button for that subscriber: OK
Really hope you have a solution. I really don’t know what to do next 🙁
Thanks,
Pierre
