CALIBRE-SMTP(1) 						      calibre							   CALIBRE-SMTP(1)

NAME

       calibre-smtp - part of calibre

SYNOPSIS

       calibre-smtp  [options] [from to text]

DESCRIPTION

       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.

       Whenever you pass arguments to calibre-smtp that have spaces in them, enclose the arguments in quotation marks.
