3.3 Debugging

Mailutils debugging output is controlled by a set of levels, each of which can be set independently of others. Each debug level consists of a category name, which identifies the part of Mailutils for which additional debugging is desired, and a level number, which tells Mailutils how verbose should its output be.

Valid debug levels are:

error

Displays error conditions which are normally not reported, but passed to the caller layers for handling.

trace0 through trace9

Ten levels of verbosity, ‘trace0’ producing less output, ‘trace9’ producing the maximum amount of output.

prot

Displays network protocol interaction, where applicable.

Implementation and applicability of each level differs between various categories. The full list of categories is available in file libmailutils/diag/debcat in the Mailutils source tree. Most useful categories and levels implemented for them are discussed later in this article.
