IMAP Access not possible since last security Update to macOS Ventura 13.4
Hi,
yesterday i installed the latest Update to MacOSX Ventura 13.4 provided by Apple. Since then i cannot access my MailPlus-Server running on my DS 920+.
The connection always times out and an error is displayed „Zugang/Passwort können nicht verifiziert werden“ / „ Account/ password cannot be verified“.
I tried the following steps:
-Restarting my MacBook and my DS 920+
-Deleting the Mail-App Mailaccounts and reconfiguring them from scrap
-Checking the passwords and account names multiple times
-Deleting the Mail-App-Settings in the Library-Folder and reconfiguring the Accounts
-Using Thunderbird as an alternative Client-App
-Testing the connection via the terminal-app using OpenSSL to get a connection and initiating a client connection by using the local ip and the dynamic ip.
the results are:
The MailServer is running perfectly, it is accessible by OpenSSL using local and global ip-addresses. So there is no problem regarding firewall-configuration or ip-blocking.
Thunderbird did have the same connection problems and was not able to connect to the server.
Next i tried to reinstall my MacBook from my last Timemachine Backup before the upgrade.
Today it does not seem to be possible to reconstruct the whole system from the backup. I was always forced to "reinstall" Ventura an then using the migration assistent to recreate all other files.
After doing that the issue persisted (as automatically the newest version of Ventura is installed)
Then i renewed the certificate on my DS920 (Lets Encrypt), assuming it is an certificate problem and checked the certificate-settings in the password manager -App (Schlüsselbundverwaltung). There all certificates seem to have the correct settings.
As the access to my mail server from my IPad and IPhone is working and my daughter and my wife have no problems and the low-level access using openssl in the terminal app also works, I´m sure that the last update causes the problem, possibly due to certificate issues or a new implementation of apple security measures, ...
My questions are:
Any other people with this problem in this forum?
Do you have perchance any solution available?
Is there any way to use my last secure timemachine backup to really reset the system to the recorded state before the last update not being forced first to reinstall the actual system?
With best regards Martin
