6. To download a report, click the Download link located in the upper right
corner of the screen. The report is opened in a new browser window that
presents the data in CSV format so it can easily be saved and imported into
most reporting and spreadsheet software for further analysis or storage.
The download report provides a comma-delimited list and is ideal when you
wish to view more than the top 20 results.
Inbound and Outbound Reports
Following are descriptions of the reports for incoming and outgoing mail traffic.
The list of reports in the Administration Console depends on your configuration.
For example, you do not see the Content Manager reports unless you have this
feature, and have turned it on.
Outbound service is an optional feature; whether the Outbound Reports are
displayed depends on your product configuration.
Summary Reports
Summary reports calculate the totals for various types of report for a specific
domain -- for example, Spam, Virus, Attachment Manager, and Content Manager
reports. The totals are summarized in two different types of report -- the total
messages processed and the total bytes processed for that domain.
Summary by Domain Messages
This report displays the total messages processed for various types of reports for
a specific domain.
Two types of Summary by Domain Messages reports are available. One report
aggregates all messages for sub-domains and aliased domains to the primary
domain. A second type of report -- the Domain Messages (& sub-domains)
report -- includes all sub-domains and domain aliases exactly as they were
received without any mapping to a primary domain. The fields in these two reports
are identical (with the exception of “Domain Message Traffic”), and each report
has the same total messages processed.
Field Description

not include messages forwarded as “Delivered
