Q0015
Question
What does the message Socket bind() to port 25 for address (any) failed: address already in use mean?
Answer
You are trying to run an Exim daemon when there is one already running - or maybe some other MTA is running, or perhaps you have an SMTP line in /etc/inetd.conf which is causing inetd to listen on port 25.
