New Hotfix Appliance Release 15.0.4.3

A new SEPPmail Appliance hotfix release has been published.

Unfortunately, we had to release another hotfix release due to PGP encryption and decryption issues.
The main problem was that many PGP keys are still in use that rely on obsolete algorithms marked as insecure, such as ElGamal or DSS.
The newly included Sequoia GPG rejects these algorithms by default, which caused encryption and decryption problems.
For now, we will allow Sequoia to use all algorithms that are supported by the original GPG.
In upcoming releases, we will add warnings for these algorithms. Later, we will also add configuration settings to enable or disable their use.

Please see the revision history and the extended release notes for further details.
