          calibre-smtp [options] [from to text]

       Send  mail  using  the  SMTP  protocol.  calibre-smtp has two modes of operation. In the compose mode you
       specify from to and text and these are used to build and send an  email  message.  In  the  filter  mode,
       calibre-smtp reads a complete email message from STDIN and sends it.

       text  is  the body of the email message.  If text is not specified, a complete email message is read from
       STDIN.  from is the email address of the sender and to is the email address  of  the  recipient.  When  a
       complete email is read from STDIN, from and to are only used in the SMTP negotiation, the message headers
       are not modified.

              Path to a file of  concatenated  CA  certificates  in  PEM  format,  used  to  verify  the  server

              behavior in calibre versions before 3.27. If you are using a relay with a self-signed or otherwise
              invalid certificate, you can use this option to restore the pre 3.27 behavior
