+ Path to a store of trusted CA certificates for SMTP SSL/TLS
+ certificate validation (either a directory that has been processed
+ by 'c_rehash', or a single file containing one or more PEM format
+ certificates concatenated together: see verify(1) -CAfile and
+ -CApath for more information on these). Set it to an empty string
+ to disable certificate verification. Defaults to the value of the
+ 'sendemail.smtpsslcertpath' configuration variable, if set, or the
+ backing SSL library's compiled-in default otherwise (which should
+ be the best choice on most platforms).
