Emails stopped flowing on Oct. 5

Resolved

(@steve49589)

I had GMail SMTP set up and working fine through late in the day on Oct. 5. I’m pretty certain I did not make any changes on that date. There was a server move on Sept. 22, but that was almost two weeks prior to the problem.

When sending a test message, this is what I get. Can you provide any insight or help?

Also, do you have any documentation on how to COMPLETELY remove the plugin, all information and clear/delete the connection with GMail? I wanted to try a complete wipe and start completely over with this plugin to see if it was a setting issue or a reset, but I could not seem to remove everything on the WP AND the Google side.

Here is the log…

It turns out the issue was a change to the server settings. Readers may find this helpful in the future. It took some time to find the cause since the error in the log file was not too helpful. I do not think the log file or plugin could have pointed us to the issue, but I’m not sure if it can be something to look for in the future.

Restrict outgoing SMTP to root, exim, and mailman (FKA SMTP Tweak) was set to YES and it needs to be NO.

This change was made by my server host during a PCI Compliance review and they didn’t tell me they made the change. That is what broke the connection.
