Outlook + MDaemon with SSL

Posted on 2004-08-23

Last Modified: 2008-03-03
I created my own SSL certificate in MDaemon mail server and it works OK, but the problem is that I always (on every launch) get a warning message in Outlook... First the message was:

"A certificate chain processed correctly, but terminated in a root certificate which is not trusted by the trust provider"

Then I exported the certificate on the server and downloaded it to client machine... then I installed it and now I get a different warning:

"The server you are connecting to is using a security certificate that could not be verified. The certificate's CN name does not match the passed value."

How do I get rid of that annoying message?

Hi Darko, contact the certificate provider. Sounds like it was installed incorrectly or not authenticated properly. In any event, if you are unable to get the solution from either of these, let me know and we will have your question moved to security TA
Good luck

Hi Karen and thanks for your answer...
Well the thing is that I have created the certificate by myself so it's not actually certified/trusted :)

So basically I would like to know if there is any way to use this "unsigned" certificate normally without warning messages every time user launches Outlook....

Well, do you need the certificate? Can you remove it? Take a look in Tools, Options Security and see what can be set here. Also, check and see if you have an option for Tools/Profiles that sometimes creates with security programs

Well if I remove the certificate from client machine, I get the first warning on every launch:
"A certificate chain processed correctly, but terminated in a root certificate which is not trusted by the trust provider"

I have looked through all options but I couldn't find anything useful...

This is a "Subject" property of the certificate:

CN = webmail.mydomain.com
O = mydomain
C = SI

In Outlook I have set incoming mail server to webmail.mydomain.com...

btw, where are these certificate stored in Windows? I downloaded this certificate to client machine and clicked Install, but I didn't remove the certificate I was using before that...  (I didn't find where I can remove it)
