 +====== Issues ======

 +====== F=<>: Unrouteable address ======
 +
 +<code>
 +www-data@hostnaname.example.com F=<>: Unrouteable address
 +</code>
 +
 +Test routing path:
 +<code>
 +exim -bt www-data@example.com
 +
 +DEBUG: system_aliases for www@example.com
 +DEBUG: procmail for www-data@example.com
 +www-data@example.com is undeliverable: Unrouteable address
 +</code>
 +
 +So the reason of problem is suffix based aliases search pattern. Address ''www-data'' is translated to ''www'' which doesn't exists.
 +
 +**Workaround:**  add some workaround aliases like:
 +<code>
 +www@example.com: user
 +www: user:
 +</code>

 +Reason:
 +
 +**Apache Module MPM ITK**
 +The MPM ITK Apache module implements restrictions on the use of the setuid() function and the setgid() function. As a result, scripts that depend on these functions may encounter problems. This includes scripts that use the mail() function, the shell_exec function, or the sudo command. 
 +
 +You can resolve these restrictions with one of the following methods:
 +
 +  * Do not use the MPM ITK Apache module. 
 +  * Update your script to no longer require escalated privileges.
 +  * Turn off the security and allow users to execute scripts as the root user. You can allow users with a UID or GID between 0 and 4294496296  to bypass security if you add the following code to your ''/etc/apache2/conf.d/includes/pre_virtualhost_global.conf'' file. 
 +    <file>
 +    <IfModule mpm_itk.c>
 +    LimitUIDRange 0 4294496296
 +    LimitGIDRange 0 4294496296
 +    </IfModule>
 +    </file>
 +    
 +    **Warning:**  We strongly recommend that you do not enable root privileges for your users. This action has major security implications and could endanger your server.
 +
 +To work around it, you would have to change your php or php-apps to 
 +send mails via SMTP to localhost instead of invoking /usr/lib/sendmail 
 +directly. I can't give any advice on how to do that, though. Or maybe 
 +there is some way to install some minimal MTA like ssmtp or nullmailer 
 +as /usr/lib/sendmail that forwards the mail to exim via SMPT. Not sure 
 +how easy it is to install those parallel to exim, though. Maybe it 
 +could work by diverting exim's /usr/lib/sendmail .
