Emails are essential tool / facility on web server to manage all communications among users.
Here are few issues:
1. Send mail function is not configured
2. No responsible mail server service on web server
3. Email port blocked
4. SMTP service
5. IP blacklist
How to fix:
1. Check Mail server (sendmail or postfix) on server
# ps -aux (check all processes for mail service)
# chkconfig –list (check mail service)
# rpm -qa | grep sendmail
# rpm -qa | grep postfix
2. If there is no Mail server then install
# yum search sendmail
# uname -i (check server arch.)
# yum install sendmail.x86_64 sendmail-cf.x86_64 sendmail-devel.i386 sendmail-devel.x86_64 sendmail-doc.x86_64
# chkconfig –list
# ps -aux
# service sendmail start
3. Now create a test email.php file
<?php $to = "[email protected]"; $subject="Testing mail...."; $message="Welcome to svnlabs.com"; mail($to, $subject, $message); ?>
4. If you still no mail yet… 🙁 Check mail logs
# tail -f /var/log/maillog
# less /var/spool/mail/root
5. Finally check network setting for DNS & SMTP
# vi /etc/sysconfig/network
# service sendmail restart
