Using your own mailing server – Certificate Failure Problem

You might get an error message like this when checking the connection:
Certificate failure for [server] Server name does not match certificate
or: “Certificate failure for [server] unable to get local issuer certificate“.
If this is the case, read the following: if you use your own mailing server (with a self-signed certificate), you might have to deactivate the automated certificate check to get a connection to your inbox. Do this by adding the following line in the special parameter box: /novalidate-cert

Help us to expand this list!

If you use a public mailing list provider that is not in the above list: mail us your settings (of course without your password 😉 ) to info@brandt-oss.com and help other Mailster users to get started more quickly.

Note: We do not recommend a certain mail provider and do not state that the usage of one of the given providers is in accordance with their respective terms & conditions. We do not endorse or accept any violation of the providers’ service conditions. It is your own responsibility to ensure your usage complies to the terms & conditions of your email service provider. Make sure you read and understand the terms & conditions and, if necessary, use another suitable mail provider.
