Traditionally email has been used in Linux to communication or inform the user about some kind of problems. In the current environment it is rather difficult to set up a good mail server so that outgoing mail does not end up in spam.

This project exists to simplify the notification to the end user. In Linux all programs that want to send an email somewhere always use/usr/sbin/sendmail. This project implements that command and also provides a mail-transport-agent package so that it is possible to send mails manually e.g. with themailutils orbsd-mailx packages (these require that an MTA is installed, usually Postfix/Exim/Sendmail and so on).

There are two ways to install it:

1. Recommended

   • go toReleases and download currenttg-sendmail_x.x.x_all.deb
   • install:

   sudo apt install ./tg-sendmail_x.x.x_all.deb

   • optionally (to send mails as user):

    sudo apt install bsd-mailx# or mailutils

2. Manual

   • clone this repo
   • copy files to their destinations:

    sudo cp src/sendmail.py /usr/sbin/sendmail sudo cp src/sendmail.ini /etc/tg-sendmail.ini# fill values sudo touch /var/log/tg-sendmail.log sudo chmod 666 /var/log/tg-sendmail.log

git clone https://github.com/conformist-mw/sendmailcd sendmailsudo apt install devscripts debhelper dh-exec dh-make dh-pythondebuild --no-lintian

After installation, you can check how it works for cron tasks, which notify the user by email in case of an error:

• add a knowingly erroneous command to the cron:

***** /usr/bin/non-existent-command

Send emails:

$echo'Mail from the server'| mail -s'Test subject' oleg.smedyuk@gmail.com

Send files (see telegram bot apilimitations):

$ sendmail --send-file /var/log/tg-sendmail.log
