Sendmail works fine on redhat but PHP unable to use that
 

Hi, I have problem sending mail with PHP. on LAMP (redhat 7 server). I configured "sendmail" which I am able to send email using the following command:
$ sendmail toemail@something.com <press enter>
message body <press enter>
ctrl+d (sends message)
and the message is received by any mentioned email address, successfully.
But when I use PHP scripts (working fine on other servers), PHP scripts are unable to send any email.
No error is there in /etc/mail/maillog.
and I have tried with different paths in php.ini in sendmail_path
e.g:
usr/sbin/sendmail -t -i

usr/sbin/sendmail -t

usr/sbin/sendmail
neither of the three does anything.

permission for /usr/sbin/sendmail is 666

Please suggest.

You mean there is no trace in the mail log.

What distro and version is this?
What's the PHP code?
Can you confirm that the PHP code that executes sendmail is actually executed?

To be honest, I don't know PHP, but is there any place where an error in a PHP program would be logged? I am asking because a path name without leading slash, like usr/bin/sendmail, is very unlikely to work.

EDIT: /etc/mail/maillog is a strange location for a log file. Is it a symbolic link to /var/log? Regarding mail logs, see also http://serverfault.com/questions/596...og-of-sendmail.

SELinux was enabled
 

Thanks for the reply. It worked. The reason of it not working was SELinux was enabled.
