TABLE 25-1
Exim Log File Messages
Symbol Description Explanation
<= Message arrival These entries show messages coming into Exim, generally
through SMTP or local IPC.
=> Message delivery These entries show message deliveries, whether they are to a
local mailbox or to a remote host using SMTP or some other
transport.
-> These entries show delivery to additional addresses for
messages that have already been delivered to another
recipient (and logged with an => entry).
** Delivery failure These entries show permanent delivery errors. Errors such as
these indicate that the message has been removed from the
mail queue and in most cases a DSN (Delivery Status
Notification) has been generated and sent to the original
message sender.
== Delivery deferral These entries show temporary delivery problems. The system
will continue to retry sending these until delivery succeeds, or
a permanent failure occurs as a result of a retry timeout.
The tail utility is useful for watching for new entries to a log. Use the -f switch to instruct
tail to watch for new entries and display them to the screen as they are written to the
log.
