how to use sendmail in 1.14.2

Hello!

Please, specify the cmdline you used.

-t is implied, sendmail always gets recipients from message body.
-s is specific to mail "composer", not sendmail, since the latter is
intended to only properly _send_ its input.

Are you trying to send to gmail.com, or to _plain text_ authenticating
server? You don't need any helper in the latter case, just use
ssmtp-fic -au<user> -ap<pass> instead. And if your server doesn't
require any authentication, you use simply -S server[:port].

Just let us know the cmdline you used before.
