incompatibility leads to silent failure

The plugin seems to be incompatible with the “WP Mail Logging” plugin.

I have been using basic wp_mail for a couple of years with a couple of small customisations. Sender is an address from a Google workspace account, with appropriate SPF and DKIM from the web host as allowable sender. Now my ISP is throttling some alerts, so I need to use GMail servers directly.

The setup of your plugin worked, I created the credentials eventually and got the green tick for SMTP status all set up. It was still giving a red alert saying I needed to input credentials or grant permission – even after I had done both. So that is a bug, as it must have needed something else, but did not say what.

The next problem was send a test email. That worked (apparently). Except: it was still using the web host’s smtp server, not GMail’s. So it all seemed to work, the email arrived, but I had to inspect the headers to check the path.

The only hint was that the “From:” value had changed from the email address I had configured in WP admin settings to “wordpress@my-test-domain”. Luckily the envelope sender remained at the value I had assigned, so spf and dkim still passed

I then disabled the “WP Mail Logging” plugin and the test email went through the expected GMail path. I was very surprised to also see the packet flow for the test email appearing in the test email tab – please put a notice there to tell users what to expect in a properly working system, and show an example in the guide.

I presume by options are either disable logging, or use a bloated alternative.
