20. Command-Line Interface to Exim > Options for Debugging

Options for Debugging

It is helpful, both to its author and to its users, if a complicated program like Exim can output some information about what it is doing to make it easier to track down problems. You can ask Exim to write debugging information to the standard error stream by setting the -d option. This can be followed by a number; the higher the number, the more information is output. Without a number, -d is the same as -d1, and for compatibility, -v and -ov (for “verbose”) are additional synonyms.

The maximum amount of general information is given when -d9 is set; -d10 gives, in addition, details of the interpretation of filter files, and -d11 or higher turns on the debugging options for DNS lookups, causing the DNS resolver to output copies of its queries and the responses it receives from name servers.
