Use php mail() function with custom exim installation

Question

I have an exim installation in a non-standard path.

How can I configure php so that mail() will use it?

Answer 1

The solution is to change the value of the "sendmail_path" variable in php.ini:

sendmail_path="/my_custom_path/exim -t -i"

exim is compatible to sendmail when it comes to command line arguments

Answer 2

After guarantee that exim4 is really running without any problem.

sudo service exim4 status

or

 sudo /etc/init.d/exim4 status  

Note .: Pay attention to result at the command line. It'll warn you, if it has any problem.

\n * Stopping MTA for restart \n * Restarting MTA \nALERT: exim paniclog /var/log/exim4/paniclog has non-zero size, mail system possibly broken \n

You may edit the file

 /etc/php5/apache2/php.ini  

and add the line

 sendmail_path = "/my_custom_path/exim -t"  

without the option -i which will cause problems.

So, type that to test,

 echo "Testing."  |  mail -s Test example@gmail.com  

instead of test with PHP function. There are so many things (firewall, network: subnets and security groups, PHP settings) that can cause problems to your routine that's better guarantee exim4 works.
