Insecure SSL on email

[tutods]

Hi guys
Anyone can help me to fix the insecure warning on email ssl?
Already have troubles on one website because that.

Already try create a new SSL but not fixed!

I have the exact same issue.
All my SSL is up to date on the server.
I am not receiving email to mobile device.
When I check to see if things are ok on the mobile device for Incoming , I get a "Certificate not valid"

Everything is up to date on SSL.

Not sure what's happening.

I hope i understand you right, do you mean the Webmail isn't using https or are you talking about postfix connections?

If you mean postfix you can create a cert for the communication with the following command:

openssl dhparam -out /etc/postfix/dh_3072.pem -2 3072

this will create a ssl cert for postfix communication.
