12.3 Trace Files

It is possible to log an entire SMTP session to a file. This is called session tracing. Two options are provided for this purpose:

--trace-file=file

Sets the name of the trace file, i.e. a file to which the session transcript will be written. Both the input commands, and the mtasim responses are logged. If the file file exists, it will be truncated before logging. This, however, can be changed using the following option:

-a

--append

If the trace file exists, append new trace data to it.
