Usage

ssh mailer allows sendmail to use "sendmail -bs" (SMTP over sendmail's STDIN & STDOUT) started using ssh on another host.

It can be used as outgoing relay (smart host) for dialup/dynamic connections. It can be also used for privacy protection (hidding details about sending hosts in Reveived: headers).

Install

In sendmail distribution append ssh.m4 (the gpg signature) to cf/mailer/ directory.

In *.mc file add

define(`SSH_MAILER_USER',`user:group')dnl
define(`SSH_MAILER_DIR',`_working_dir_')dnl
MAILER(`ssh')dnl

Modify user:group and _working_directory_ to fir your system requirements.

Modify ~user/ssh/.config to allow use executing "sendmail -bs" on the remote host using key authentication. See "man ssh_config" for details.
