All my mail comes though my current mail in a box, but for the last couple months I have been getting a notice that the security certificate can not be verified. A friend of mine set this mail box up a number of years ago, and unfortunately he passed away. My question is how do you re-certify this mail system? Thanks!!!
From the comment that a friend set this up a number of years ago, I am going to assume that there has not been any updates, or maintenance applied …
Years ago, MiaB would have been set up on the Ubuntu operating system version 14.04. That operating system is out of date and no longer supported which is a huge security risk for you. This also explains why SSL certificates are no longer being renewed.
The solution is to upgrade your service to a newer version. This may or may not be simple - dependent upon whether or not you are using NextCloud.
Instructions for upgrade may be found here: Mail-in-a-Box Maintenance Guide
If you’d prefer, I can do the upgrade for you for a reasonable fee.
Please feel free to contact me for assistance!
