Comments: 0 Comment out the option skip-networking in the file my.cnf which typically lies under /etc or /etc/mysql. Then restart your MySQL server: /etc/rc.d/init.d/mysql restart or /etc/init.d/mysql restart With netstat -ta you can check if MySQL is reachable via TCP.

On sending emails, I get the following error message: "Relaying denied".
Author: Till Brehm •
Tags: postfix, sendmail •
Comments: 0 There are two solutions for this problem: 1) You configure your MTA to allow authentication via SMTP (SMTP-Auth). Your users then have to change settings in their email clients (e.g. Outlook), i.e., they have to activate Server requires authentication. 2) You install "POP-before-SMTP" or poprelayd on your server. Your users then have to fetch emails first before they are allowed to send emails for a restricted period of time (mostly 30 min.).

Comments: 0 One of the users on the system has a CatchAll-email address. He receives all emails, even those intended for users of another site on the same server. The MTA on the server is postfix. Please check if the domain of the users that receives all emails is the same as the domain $mydomain in /etc/postfix/main.cf. If this is the case, change $mydomain and run postfix reload on the shell. You should never enter a domain that is used for a virtual site on the server as $mydomain in /etc/postfix/main.cf!
