Php – Ubuntu Jaunty + sendmail + PHP + mail() Premission Errors

apache-2.2permissionsPHPsendmail

I'm having issues trying to get PHP's mail function to work on my Ubuntu 9.04 VPS with sendmail and Apache (and other less relevant stuff, of course).

From PHP I receive no error, save a return value of false from the mail function.

The last error in /var/log/mail.err is

sendmail[14837]: NOQUEUE: SYSERR(www-data): can not chdir(/var/spool/mqueue-client/): Permission denied

Now, I appreciate that this is saying www-data (the user Apache is running as) does not have read access on some required directory (/var/spool/mqueue-client).

So, knowing that (and for test purposes only), I ran chmod 777 /var/spool/mqueue-client and reran the script, which this time succeeded (hurray), however /var/log/mail.err now says

sendmail[14874]: dangerous permissions=42777 on queue directory /var/spool/mqueue-client/

So I'm wondering how I can configure things so my script can run using non-dangerous permissions.

You could try to chmod 775 the /var/spool/mqueue-client and then add www-data to the smmsp group. I agree though if you can switch to postfix somehow, you would be much better off.

Ubuntu – PHP mail() not working with Postfix on Ubuntu

Oh, I fixed the problem by following the information in this forum:

http://ubuntuforums.org/showthread.php?t=666018

Basically, I looked in my /var/log/mail.log error file and found the error message "unable to look up public/pickup: no such file or directory".

I then issued the command

sudo mkfifo /var/spool/postfix/public/pickup

I made sure sendmail wasn't still running by doing a ps -aux and killing it

root@cpu:/var/log# ps aux | grep mail
root      2363  0.0  0.5   9228  1888 ?        Ss   Jan28   0:20 sendmail: MTA: accepting connections          
root     23914  0.0  0.2   3040   792 pts/0    S+   11:33   0:00 grep mail
root@cpu:/var/log# kill 2363

I restarted postfix

sudo /etc/init.d/postfix restart

And now the PHP mail function works.

Ubuntu Server mod_chroot Apache2 Problem

My guess would be that Apache is trying to write the PID file after it's done the chroot - i.e. when Apache think's it's trying to write to /var/chroot/apache/var/run/apache2.pid, it's actually trying to write to /var/chroot/apache/var/chroot/apache/var/run/apache2.pid

Check the Apache config files to see what PidFile is set to - it probably should be just

PidFile /var/run/apache2.pid

See http://core.segfault.pl/~hobbit/mod_chroot/apache20.html for other config tweaks you may need to do to use mod_chroot with Apache 2.x
