TODO
Email processing is a complex task and involves several service
daemons. Each daemon logs information to the syslog service. The
problem is that a servers analyzes many emails in parallel, so it is
usually very hard to find all logs corresponding to a specific mail.
Introduced in {pmg} 2.1, the tracking center simplifies the search for
emails dramatically. We use highly optimized C-code to search the
available syslog data. This is very fast and powerful, and works for
sites processing several million emails per day.
The result is a list of received mails, including the following data:
[cols="s,5d"]
|====
|Time | Timestamp of first found syslog entry.
|From | Envelope 'From' address (the sender).
|To | The email receiver address.
|Status | Delivery status.
|Syslog | The corresponding syslog entries are shown if you double click such
entry, or if you press the '+' button on the left.
|====
Please notice that you can specify filters, most important you can set
a 'Start' and 'End' time. By default the start time is set to one hour
ago. If you still get to much result entries, you can try to restrict
the search to specific sender or receiver addresses, or search for a
specific text in the logs ('Filter' entry).
