+Subject: [PATCH] Add Alpine system configuration file that specifies location

+
+The system-certs-file configuration option is provided to
+SSL_CTX_load_verify_locations() as the CAfile argument (via
+imap/src/osdep/unix/ssl_unix.c).
+
+system-certs-file and CAfile are used (as opposed to
+system-certs-path and CApath, used to specify a directory)
+because certificate files within the CApath directory must follow a
+specific naming convention, where the filename matches the CA subject
+name hash value.
+
+See man 3 SSL_CTX_set_default_verify_paths for details on how OpenSSL
+looks up CA certificates.
