I have a self signed certificate which is being used my one of our messaging server in our company. Recently I realized that certificate was expired 2 years back but it is still working is being used as the authentication to client. I am wondering how it is possible. Please note we have local company specific root CA. Please help me to understand how it is working in this scenario, I can provided more specific information in this regard. Thanks!

My understanding is that yes they still perform the SSL encryption. Of course it will continually prompt clients to accept the expired certificate. Whereas a good certificate would avoid the issue.

Yes it will continue to work but will prompt. I would suggest buying a cert or you can get a free trusted one from http://cert.startcom.org/
