Certificate not trusted

Since updating to latest operating system on my iPad I have had difficulty sending emails. I am getting a message that the Certificate for my mail server is not trusted. It has a certificate which is valid until April 2033. My server is Internexus Group. How do I resolve this and how did this change between OIS 11 and 12?

iPhone 5s, iOS 8.1.2

Verifying a updated mail certificate on iPhone/iPad I recently signed a self signed certificate that was about to expire on my High Sierra server. Now I am unable to connect on my iDevices while I can on my Macs When retrieving mail from my Mac I was able to accept that certificate and use it for sending and receiving mail. On the iDevices, I get a pop up saying "cannot verify server identity." I was able to view the details of the certificate yet, unlike on the Mac, I am not able to accept it. I have tried deleting the account and when I go to create it again, I get a message first that it cannot connect using SSL and then when it tries to set it up without SSL it claims "No password provided for [server_name] and that should go to mail account settings to enter a password, but I did with Settings>Accounts>Add Accounts>Other>Add account. (Again this is a personal High Sierra Mail Server). Once again, the Macs can connect just fine. I have been able to do this in past when I have updated the self-signed certificate. I am not sure why it is not working this time. I have tried using mail.[server}.com and have tried using the IP address. The response I first get is cannot connectives SSL and when I try and connect without, I get a message that it cannot connect to mail server. The account settings were entered exactly as they appear in the Mail App on the Mac under Mail>Preferences>Accounts How do I fix this?

Cannot Verify Server Identity (Mail App) Bought iphone 7 plus, updated to latest IOS 15.1. When adding an Exchange account in the "mail" application, an error appears: Cannot Verify Server Identity The identity of "my.mail.com" cannot be verified by Mail. "my.mail.com" is self-signed certificate. When adding it to trusted certificates, the error does not disappear. I also tried to delete the account from the "mail" application and reboot the iphone itself. Is there a solution to this problem? Previously, it was possible to simply accept the certificate upon request and use it.
