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, mail() returns false and the email never gets sent. Nothing appears in the exim mainlog.

Any advice, or things I should look for ?

What distro? Are you running in an SELinux-protected configuration? – jgoldschrafe Nov 8 '10 at 12:01
@jgoldschrafe Debian 5.0.6 and no. – jfoucher Nov 25 '10 at 19:09

It sounds like you've got different versions of php.ini located under /etc/php5/

debian:/etc/php5# find . | grep php.ini

Check the [mail function] directive

I did, they're the same in both files. I actually copied one to the other (and the other way around) and got the exact same results – jfoucher Nov 25 '10 at 19:11
Do a phpinfo() and add the php server information "sendmail" to your question. Exim will normally replace the sendmail binary with the send compartible exim binary. – DrDol Dec 28 '10 at 22:39
