Subject: [PATCH] [Web] Add hint to DKIM key import for RSA PKCS#8
Adding hint to explicitly provide a RSA Private key in the newer PKCS#8 format, as the webinterface denies the key with a cryptic error message otherwise: `Private key error: error:0EFFF06C:configuration file routines:CRYPTO_internal:no value`. To prevent frustrated users I'd add a simple notice which format is expected. PKCS#8 is also the default format when generating keys directly in the webinterface.
