The MSMTP mail client is a small program capable of sending messages. I use it for sending messages from my server.

My working configuration is below. (password have been removed)

 # default values
 defaults
 auth            on
 tls             on

 # for debian based systems
 tls_trust_file  /etc/ssl/certs/ca-certificates.crt

 # for rhel based systems
 #tls_trust_file  /etc/pki/tls/certs/ca-bundle.crt

 #tls_starttls   off
 logfile         /var/log/msmtp.log
 
 # Syslog logging with facility LOG_MAIL instead of the default LOG_USER.
 syslog LOG_MAIL
 
 aliases         /etc/aliases
 
 # one.com
 account one
 host send.one.com
 port 465
 from no-reply@example.com
 user no-reply@example.com

 auto_from off
 domain example.com
 tls_starttls off
 
 # Set default account
 account default : one

Create a text file named “email.txt” and put some content in it.

 To: me@example.com
 From: no-reply@example.com
 Subject: Email test from CLI
 Hi,
 
 This is a test message from my server.

Send a test email with this command. Please note that when send as normal user the log file is not accessible.

 john@server:/tmp$ cat email.txt |msmtp -a one me@example.com
 msmtp: cannot log to /var/log/msmtp.log: cannot open: Permission denied
 msmtp: log info was: host=send.one.com tls=on auth=on user=no-reply@example.com from=no-reply@example.com recipients=me@example.com mailsize=154 smtpstatus=250 smtpmsg='250 2.0.0 Ok: queued as 616eb246-fabb-11e8-b718-d0431ea8a290' exitcode=EX_OK

Sending email using msmtp is all well and good but if you want to send a message with an attachment it just won't do it.

That's where Mutt comes into the picture.

Typically installing mutt can be done with either “yum install mutt” or “apt install mutt”.

You don't need to configure anything, but the from field of your message will then be username@server. if you create a config file you can set the from field to anything you like. Create the file /root/.muttrc if it does not exist.

set use_from=yes
set realname=”no-reply”
set from=no-reply@example.com
set envelope_from=yes

note: if the realname contains a space you should set the value in both double quotes and single quotes. e.g

set realname="'John Doe'"

A test email can be send with the following command. (test.txt is the file to attach and body.text is the message body)

john@server:~$ mutt -s "Testing Mutt" -a test.txt -- recipient@example.com < ./body.txt
