A web server I manage is having problems sending mail from PHP. This server uses exim4 for MTA, and it is configured correctly.
I can send emails from PHP's CLI, but not from the web. i.e. if I do "php mailtest.php" on the command line, the email gets sent correctly, but if I browse to server.com/mailtest.php, mail() returns false and the email never gets sent. Nothing appears in the exim mainlog.
Any advice, or things I should look for ?
Thanks!
It sounds like you've got different versions of php.ini located under /etc/php5/
debian:/etc/php5# find . | grep php.ini
./cli/php.ini
./apache2/php.ini
Check the [mail function] directive
You should change your PHP configuration to send emails through exim.
If you use Apache2 as a webserver:
; /etc/php5/apache2/conf.d/mail.ini
[mail function]
sendmail_path = /usr/sbin/exim4 -t
mail.add_x_header = On
mail.log = syslog
If you use nginx+FPM:
; /etc/php5/fpm/conf.d/mail.ini
[mail function]
sendmail_path = /usr/sbin/exim4 -t
mail.add_x_header = On
mail.log = syslog
Then restart your services:
sudo service apache2 restart
or:
sudo service php5-fpm restart
