14.3 Log with syslog | 517
The third line sends authorization messages (such as repeated login failures) to the
host named authhost.
The fourth line appends all messages printed by sendmail at level info and above to
the file /var/log/syslog.
The last line is an alert broadcast facility. A message to any facility (the leftmost *) at
the highest level (alert), except for the facility user (the .none), will be written to the
screen of all currently logged-in users (the target *).
Finally, note that facilities can be listed together by using a comma:
mail,daemon.info
This causes the level info to be the level for both the facilities mail and daemon. Only
the facility can be listed this way. The level cannot, and (unfortunately) the target
cannot.
14.3.3 syslog??™s Output
When the LogLevel option level is 9 or above (?§24.9.61 on page 1040), sendmail logs
one line of information for eachenvelope sender and one line of information for each
recipient delivery or deferral. As sendmail has evolved, these lines of logging information
have grown more complex. Here, we discuss the lines produced by sendmail
8.12.
Each line of information logged looks something like this:
date host sendmail[pid]: qid: what=value, ...
Eachline of output that syslog produces begins withfive pieces of information. The
date is the month, day, and time that the line of information was logged.
