PHP mails not working on Cpanel Server
On a cpanel server, PHP scripts can’t sent email. Incoming and outgoing emails for email users (mailbox) are working properly.
To debug, loggged in to SSH as one of the cpanel user.

If SSH access is not enabled, enable SSH in WHM.
Once logged in, verify sendmail works.

[sabtempco@buffalo ~]$ sendmail -f noreply@serverok.in admin@serverok.in sendmail: Not running with correct effective GID. Is sendmail binary setgid mailtrap? sendmail: Not running with correct effective GID. Is sendmail binary setgid mailtrap? [sabtempco@buffalo ~]$ |
I get above error message. This is because permission error with /usr/sbin/sendmail.
To fix, run

chmod +x /usr/sbin/sendmail chmod g+s /usr/sbin/sendmail chown root:mailtrap /usr/sbin/sendmail |
