Setup and Configure SSMTP and MAILUTILS to send email from system, ie: alarm notification, crontab’s message…
This tools is useful that you do not need to setup a MTA (Mail Transfer Agent) like SMTP Server, Sendmail… to deliver system’s message.
root@ubuntu:~# sudo apt install ssmtp mailutils root@ubuntu:~# cat /etc/ssmtp/ssmtp.conf #-------------------------------------- # # Config file for sSMTP sendmail # # The person who gets all mail for userids < 1000 # Make this empty to disable rewriting. root=<ie: postmaster@infotechviet.com> # The place where the mail goes. The actual machine name is required no # MX records are consulted. Commonly mailhosts are named mail.domain.com #mailhub=mail mailhub=<your email's servcer:port> AuthUser=<your email's account> AuthPass=<your email's password> UseTLS=YES UseSTARTTLS=YES # Where will the mail seem to come from? rewriteDomain=<ie: infotechviet.com> # The full hostname hostname=<ie: infotechviet.com> # Are users allowed to set their own From: address? # YES - Allow the user to specify their own From: address # NO - Use the system generated From: address FromLineOverride=YES #--------------------------------------
Test sending an email:
root@ubuntu:~# echo "Hello, this is mail content for test" | mail -s "Hello test!!!" "info@infotechviet.com"
Tips:
Configure alias for root, or postmaster to forward system’s message to your expect email address.
root@ubuntu:~# vi /etc/ssmtp/revaliases #---------------------------------------- # # sSMTP aliases # # Format: local_account:outgoing_address:mailhub # # Example: root:your_login@your.domain:mailhub.your.domain[:port] # where [:port] is an optional port number that defaults to 25. root:nghiale@infotechviet.com romano:nghiale@infotechviet.com postmaster:nghiale@infotechviet.com # #---------------------------------------- root@ubuntu:~#
