I have a Ubuntu 14.0 server running with NginX on Digital Ocean .
I tried to add following PHP code
@mail($email_to, $email_subject, $email_message, $headers);
But its not working
so I googled and followed following tutorial
https://holarails.wordpress.com/2013/11/17/configure-sendmail-in-ubuntu-12-04-and-make-it-fast/
So now My hots file look like this
# Your system has configured 'manage_etc_hosts' as True.
# As a result, if you wish for changes to this file to persist
# then you will need to either
# a.) make changes to the master file in /etc/cloud/templates/hosts.tmpl
# b.) change or remove the value of 'manage_etc_hosts' in
# /etc/cloud/cloud.cfg or cloud-config from user-data
127.0.1.1 iclock iclock
#127.0.0.1 localhost
127.0.0.1 localhost localhost.localdomain iclock
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
and then I run following command
sendmailconfig
But still when I try sending Email its not working .
Any help would be Appreciated .
Thanks
