||<>|| = Introduction = '''Mutt''' is a small but very powerful text-based mail client for Unix operating systems. It is great for testing mail server setups and sending email messages via the command line. = Installation = Mutt has '''mail-transport-agent''' as a dependency which means if you don't have a Mail Transport Agent installed on your system and you install Mutt an MTA will also be installed, [[Postfix]] being the default. If you want to install a different MTA than Postfix, [[Exim4]] for example, you will need to install the package before installing Mutt. If you don't need a full fledged and feature full MTA, but want to send messages using Mutt a good substitute is the '''ssmtp''' package in the Universe repository. '''SSMTP''' can be configured to send mail to a proper MTA or mail hub. '''Mutt''' can be installed from the Main repository see InstallingSoftware for details. = Sending Messages Via CLI = Once you have Mutt and a MTA installed sending messages via command line or bash script is simple. For example: {{{ echo "Test" | mutt -s Hello user@example.com }}} The above command will send a message to ''user@example.com'' with the subject of "Hello" '''(the -s)''' and the word "Test" in the message body. = SSMTP configuration = This section will provide instructions on using the '''ssmtp''' package to deliver mail to another MTA. The SSMTP configuration file is {{{/etc/ssmtp/ssmtp.conf}}} edit the following options: {{{ mailhub=mta.example.com hostname=your_local_machine }}} That should do it, just make sure that you are allowed to relay messages through the host configured in the '''mailhub''' option. == SSMTP with SMTP AUTH == Here are some options you can configure if the '''mailhub''' you are using requires authentication in order to relay messages: {{{ AuthUser=username AuthPass=password UseTLS=YES UseSTARTTLS=YES }}} You may not need the ''UseTLS'' and ''UseSTARTTLS'' options. Use these options to configure TLS encryption with the MTA (usually a good idea). '''Note:''' this guide has been tested on Ubuntu 6.06 (Dapper), Ubuntu 7.06 (Feisty), and Ubuntu 7.10 (Gutsy). ---- CategoryEmail
