Mail problem

[Budolfsen]

Issue Summary

I have been using Local Wp for a long time and have never had any problems - but today I was working on a site with a supscription service and I had to test if the mails were correct - so I checked my mailhog to see them - nothing - but suddenly a customer contacted me cause she had gotten the mail which should have been contained to my local mac.

Troubleshooting Questions

This should be possible since the local wp is a closed environment - so all mails should be inside mailhog.

System Details

Local WP 5.4.2 for mac
Mac OS Ventura

Are you using a transactional mail service (e.g. Sendgrid, SES), or SMTP server? If you have one of these configured in your environment (typically via a plugin), it will still try to send out using that mail service.

I am not using any plugin to send mails - the only plugin that has anything to do with mails is sendinblue-newsletter.

But it still sends email out from my local mac - and thats kind of bad when the site is not ready yet

Looking at the description from the plugin that you referenced (Newsletter, SMTP, Email marketing and Subscribe forms by Brevo (formely Sendinblue) – WordPress plugin | WordPress.org), it would appear that with it enabled, emails will be sent out through Sendinblue’s transactional email servers. I suspect that it’s sending ALL emails out that way, not just those related to the newsletter functionality. Here’s what it says on that page:

Transactional emails – The wp_mail() function automatically uses Sendinblue’s SMTP for enhanced deliverability and tracking

Automatic replacement of default SMTP when you use wp_mail function

I would suggest disabling that plugin on your development environment, or at least disabling the sending of emails through the Sendinblue servers – there appears to be a checkbox for this on the plugin’s page in the WP admin.

Thanks that was the problem - I hadn’t seen that checkbox.
