====== Where can I find relevant logs to solve a problem? ======
According to the affected service look at these logs.

===== Webserver / Apache =====
For general problems look at
  * **/var/log/apache2/error.log**
  * **/var/log/apache2/suexec.log**

If a specific domain is affected, **also** look at:
  * **/var/log/apache2/users/affected.domain-error.log**

===== Mail / Postfix / Courier =====
  * **/var/log/mail.log** (this one contains all information)
  * **/var/log/mail.err** (this one contains only errors)

===== Bind =====
  * **grep named /var/log/syslog**

===== ispCP subsystems =====
  * **/var/log/ispcp/ispcp-***
