/* NAME
/* mail_task 3
/* SUMMARY
/* set task name for logging purposes
/* SYNOPSIS
/* #include <mail_task.h>
/*
/* const char *mail_task(argv0)
/* const char *argv0;
/* DESCRIPTION
/* mail_task() enforces consistent naming of mailer processes.
/* It strips pathname information from the process name, and
/* prepends the name of the mail system so that logfile entries
/* are easier to recognize. The mail system name is specified
/* with the "syslog_name" configuration parameter.
/*
/* The result is overwritten with each call.
/*
/* A null argv0 argument requests that the current result is
/* returned, or "unknown" when no current result exists.
/* LICENSE
/* .ad
/* .fi
/* The Secure Mailer license must be distributed with this software.
