Certificate error on opening Outlook

Postby mollcons » Sat Jan 11th, 2014 7:16am

Mailtraq Version:

Whenever I initiate Outlook (v2013), when it connects to the Mailtraq server, it pops up a message box entitled "Internet Security Warning", which says:
"The server you are connected to is using a security certificate that cannot be verified.

The target principal name is incorrect"

I am using a self-generated certificate.

How do I stop the warning being generated every time that Outlook opens?

You would have to import the certificate into the "Trusted Root Certification Authorities" store on each client which should work, or you can purchase a valid SSL certificate online at a cheap price. If the server and client are both inside a LAN and you are not worried about someone "sniffing" the network and capturing mail between the client and server, you could actually just choose not to use a certificate. Also, the name in the certificate MUST match the name of the server you are connecting to, exactly.
The problem with self-signed certificates is that they are generally not used in production and browsers and other software that are seeing the certificate will not show it as authentic.
Hope this helps a bit.

Another option to consider is a free certificate from StartSSL. Works here for email and webmail but I think Mailtraq would need to support StartSSL's Class 1 intermediate certificate to work seamlessly with non-ancient versions of Firefox. (See StartSSl's FAQ. It may be possible already but I didn't see a way of installing it).
