The encrypted message to email@address.com could not be delivered because: SPX password service temporarily unavailable on localhost:
:1: parser error : Space required after the Public Identifier
^
:1: parser error : SystemLiteral " or ' expected
^
:1: parser error : SYSTEM or PUBLIC, the URI is missing
^
This happens with both "Generated and stored for recipient" and "Generated one-time password for every email" selected as "Password type" in the SPX template. I haven't tried "Specified by sender".
