dovecot - Nov 2021 - Dovecot and certificates/keys on PKCS11 smartcards/HSMs

Hi all,

To configure SSL on dovecot using certificates and keys in files on disk, you
specify the following:

# Preferred permissions: root:root 0400
ssl_cert = </etc/ssl/dovecot.pem
ssl_key = </etc/ssl/dovecot.pem

Is there a syntax that will allow a certificate and key to be specified on a
smartcard/HSM, as is possible (for example) for httpd at
https://httpd.apache.org/docs/trunk/mod/mod_ssl.html#sslcertificatefile:

# Example use of a certificate and private key from a PKCS#11 token:
SSLCertificateFile "pkcs11:token=My%20Token%20Name;id=45?

Regards,
Graham
