I guess it is not SASL/EXTERNAL. The dialog says: Extern (TLS Clientzertifikat) I don’t know, why they call it „extern“ >> As you see, Apple Mail does have a different behavior. > > Yep, it does not employ client certificates, at least not as > configured.

And as I have no idea where to find further information, how the certificate must have been created to work with Apple Mail, I give up right now.
