I'm trying to get the PHP mail() function to work. But it fails to send emails. I run Ubuntu 11.04. I installed sendmail.

I opened the php.ini and set

; For Unix only. You may supply arguments as well (default: "sendmail -t -i").

; http://php.net/sendmail-path

sendmail_path = /usr/sbin/sendmail -t

sendmail_from = [email protected]

Then I restarted apache.

Then created a simple PHP script to test it but no luck.

When I try to run sendmail it gives me a permissions error, so I have to run 'sudo sendmail'. Does my mail system failure have anything to do with permissions? Is there further configuration I need to do with sendmail?

Thanks.

EDIT: The error is this:

user@server:~$ sendmail

Command 'sendmail' is available in '/usr/sbin/sendmail'

The command could not be located because '/usr/sbin/' is not included in the PATH

environment variable. This is most likely caused by the lack of administrative

privileges associated with your user account.

sendmail: command not found

user@server:~$ sudo sendmail

sendmail: No recipients supplied - mail will not be sent
