This is what's already there:
Q0002: Exim is not working. What is wrong? How can I check what it is doing?
A0002: Exactly how is it not working? Check the more specific questions in the
other sections of this FAQ. Some general techniques for debugging are:
1. Look for information in Exim's log files. These are in the "log"
directory in Exim's spool directory, unless you have configured a
different path for them. Serious operational problems are reported
in paniclog.
2. If the problem involves the delivery of one or more messages, try
forcing a delivery with the -d option, to cause Exim to output
debugging information. For example:
exim -d -M 0z6CXU-0005RR-00
On its own, -d produces a small amount of information. Following it
with a number increases the amount given: -d9 gives the maximum
amount of general information; -d10 gives in addition details of the
interpretation of filter files, and -d11 or higher also turns on the
debugging option for DNS lookups. The output is written to the
standard error stream.
3. If the problem involves incoming SMTP mail, try using the -bh option
to simulate an incoming connection from a specific host, for example:
exim -bh 10.9.8.7
This goes through the motions of an SMTP session, without actually
accepting a message. Information about various policy checks is
output. You will need to know how to pretend to be an SMTP client.
4. If the problem involves lack of recognition or incorrect handling
of local addresses, try using the -bt option with debugging turned
on, to see how Exim is handling the address. For example,
exim -d2 -bt z6abc
will show you how it would handle the local part "z6abc". Increase
the debug level to -d9 for more information.
