Quick and dirty email sending from a virtual server. (On Azure port 25 outbound is blocked so this works nicely sending to port 587)
You will have to tweak your gmail account to use less secure auth and allow app passwords.
Install the SSMTP package
1 | apt-get install ssmtp |
Add the configuration /etc/ssmtp/ssmtp.conf
1 2 3 4 5 6 7 8 9 10 11 | root=james@toggen.com.auhostname=site1.toggen.com.auAuthMethod=LOGINUseTLS=YESmailhub=smtp.gmail.com:587FromLineOverride=YESAuthUser=yourgmailalias@gmail.comAuthPass=YourSuperSecretGoogleAppPasswordUseSTARTTLS=YESFromLineOverride=YESDebug=NO |
Then create a script to send an email when something happens. The below script is looking in an nginx access log and will alert when an entry for the bing bot is seen.
What I like about this script is the <<- what it does is let you use a indented here doc so you don't have to step back to the left hand side of the script which is ugly. The indented text must be a Tab \t character. In effect the addtion of the - character to the << redirection says strip all leading white space from the here doc. Nice
