SMTP error: self signed certificate

I tried to setup to send emails from my own SMTP-Server, but I obtain error message that says “error: self signed certificate”. What can I do to solve that problem?

EDIT/UPDATE: There was a wrong value in the domain name field. Now it works.


The current SMTP-setup does not accept self-signed certificates. In
general, it is a VERY bad idea to use a self-signed certificate on an
SMTP-server. Your SMTP-server is exposed to the world and should have a
proper certificate. Please get a signed certificate from a vendor.

Of course, you can always use our SMTP-server and then you don’t need to
deal with this.
