Often times I want to send emails to myself when a job is done or when something happens on the computer/server. Using the command line is the most portable and obvious as most software I run (eg, R) can execute from it.
This site shows how to use
mutt to send emails from the command line, but does not show how to set things up. Setting up actually took me a long time to figure out, as I wasn’t familiar with Mail User Agent (MUA), Mail Transfer Agent (MTA), etc. This site can help clear things up regarding those issue.
Now, down to business. We’ll need to install some software:
sudo apt-get install mutt msmtp bsd-mailx ## mailutils
mailutils contain the
mutt is an MUA that allows one to send mail from the command line and attach files.
msmtp is an MTA that we can use with
mutt (mutt v1.5.x and above has it’s own built in smtp capabilities).
account default host smtp.gmail.com port 587 from my.email.address tls on #tls_starttls on tls_trust_file /usr/share/ca-certificates/mozilla/Equifax_Secure_CA.crt auth on user my.username (email address for gmail) password my.password logfile ~/.msmtp.log
Need to execute
chmod 600 .msmrprc (user read/write only )or it won’t work.
## following if want to use msmtp to send mail set sendmail = "/usr/bin/msmtp" ## set realname = "vqn laptop" set from = my.email.address set use_from=yes set envelope_from=yes ## uncomment following and comment above sendmail line if want to use ## mutt's built-in smtp ##set smtp_url="smtp://email@example.com:587" ##set smtp_pass="my.password"
chmod 600 .muttrc since it contains password.
Note that to use TLS with msmpt, you need to set the certificate file. On a debian-basd system, you can find it in the
/usr/share/ca-certificates/ directory, which has many. See below for references.
This site shows how to set up mutt with msmtp. This site shows how to set things up, along with the certificate stuff. More on certificate here. This will tell more on how to use the built-in smtp of mutt. The wiki of course has more information.
UPDATE 8/24/2011: From this post, use
bsd-mailx instead of
mailutils to have the
msmtp: no recipients found.
UPDATE 11/13/2011: If you want to be able to email as the root user, make sure these instructions are set up for the root user’s home directory,
