7.7 Logging and Debugging configuration

Mailfromd Conf: logger mech

Set default logger mechanism. Allowed values for mech are:

stderr

Log everything to the standard error.

syslog

Log to syslog.

syslog:async

Log to syslog using the asynchronous syslog implementation.

See Logging and Debugging, for a detailed discussion. See also Using non-blocking syslog, for information on how to set default syslog implementation at compile time.

Mailfromd Conf: debug spec

Set mailfromd debug verbosity level. The spec must be a valid debugging level specification (see debugging level specification).

Mailfromd Conf: stack-trace bool

Enables stack trace dumps on runtime errors. This feature is useful for locating the source of an error, especially in complex scripts. See tracing runtime errors, for a detailed description.

Mailfromd Conf: trace-actions bool

Enable action tracing. If bool is ‘true’, mailfromd will log all executed actions. See Logging and Debugging, for a detailed description of action tracing.

Mailfromd Conf: trace-program modlist

Enable program instruction tracing for modules in modlist, a comma-separated list of source code modules, e.g.:

trace-program (bi_io,bi_db);

This statement enables tracing for functions from modules bi_io.c and bi_db.c (notice, that you need not give file suffixes).

This tracing is useful for debugging mailfromd, but is not advised to use otherwise, since it is very time-costly.

Mailfromd Conf: transcript bool

Enable transcripts of call-out SMTP sessions. See SMTP transcript, for a detailed description of SMTP transcripts.
