Wrong Certificat Failure
-
I got an issue when I connect the Easy WP SMTP plugin without permission of “Insecure SSL Certificates”. The Mailserver certificate is secure and valid, it is an wildcard ssl certificat. If I set “Allow Insecure SSL Certificates” it works fine. Any ideas why it will not work with wildcard certificates?
Any help is appreciated .

Hi, can you enable debug mode and then carry out a test. Report back with any findings.
Thank you
This is the result out of the debug logfile:

In case of disabling this debug log on test page remains empty but with a failure message (Following error occurred when attempting to send test email:
SMTP Error: Could not connect to SMTP host.) and a red strip at the left side.Your best option is to speak to your host about this issue. I am curious to know myself why it is not working with your host.
Thank you
I think the issue is coming out of the plugin, any client can connect to the host (mail.euronetmail.com) outlook, thunderbird, etc. just your plugin. If I connect to a mailhost with a non wildcard certificate, it works fine. Just with the wildcard it will only work with the enabled function:

Hi,
checked the ssl certs and replaced them, now it works fine.
Thank you for your assistance.

Christoph
