Yes, I see error reports from the SMTP plugin now – mail sending limit exceeded. And just like you said, the same happened with the provider’s SMTP service.

I’ll look for an external SMTP provider.

I’ve tried to confirm 4,500 signatures with the plugin’s function “Confirm selected signatures”, but the HTTP header is too long and results in an error. Perhaps this could be a POST request instead with the siglist as payload?

Right, gotcha. I’m actually not sure if there is a sending rate limit, that’s just my assumption why it worked intermittently. Can you think of another reason why that could happen?

@123host Thank you so much, I got it working again. I was wondering how WP sends emails, whether it comes with a mail server or what else. I suspect that wp_mail was working but then, exceeding a threshold of sent emails, the provider disabled it.

I’ve switched to SMTP now.
