 ### SPECIAL INVOCATIONS
 
-`-t <protocol>, --starttls <protocol>`    does a default run against a STARTTLS enabled `protocol`. `protocol` must be one of `ftp`, `smtp`,  `pop3`, `imap`, `xmpp`, `sieve`, `xmpp-server`, `telnet`, `ldap`, `irc`, `lmtp`, `nntp`, `postgres`, `mysql`. For the latter four you need e.g. the supplied OpenSSL or OpenSSL version 1.1.1. Please note: MongoDB doesn't offer a STARTTLS connection, IRC currently only works with `--ssl-native`. `telnet` and `irc` are WIP.

 `--xmpphost <jabber_domain>` is an additional option for STARTTLS enabled XMPP: It expects the jabber domain as a parameter. This is only needed if the domain is different from the URI supplied.
