mail function not working in ec2 amazon aws php

Solution worked for me:

1. install sendmail by command: sudo apt-get install sendmail
2. check the service whether its started or not by execuring follwing command service sendmail status Note: Output of above command should be something – ‘Active: active (running)’
3. start the service if it is not running by following command service sendmail start
4. After the service is started, send a test mail using following command: echo "This is test mail body" | mail -s "Test Mail Subject" "recipient@email.com"

Replace email with your email ID and see if you receive this email, if yes, then your mail setup is fine and now your php email should be working fine.
