mailer=
The delivery agent used syslog equate
The sendmail program calls other
programs (called mail delivery agents) to perform
that delivery. Some delivery agents are external (as
for local delivery), and others are internal (as for
network delivery). The mailer=
syslog equate shows the
symbolic name (The M Configuration Command on page
711) of the delivery agent that was used to perform
delivery to the recipient:
mailer=agent
A list of symbolic names assigned to delivery agents
can be viewed with the -d0.15
debugging switch (-d0.15 on page 544). The mailer=
syslog equate is shown only for
recipient records.
