Interpreting Header Fields 409
[email protected] is the From address used in evaluating the user’s
approved- and blocked-sender lists. If the address appears on one of these lists,
the processing is terminated and the disposition is noted on this line.
The text after the address can be one of the following options. (If nothing appears,
the address was not on any of the following lists.)
[1119/49] is a summary of the user’s approved-senders list. The first number is
the total number of characters in the approved-senders list. The second number is
the total number of entries in the list. In the above example, there are 1119
characters in the approved-senders list, and the total number of entries in the list
is 49. If there are no entries in the user’s approved-senders list, the summary is
displayed as
[db-null] .
In the example below, the message bypassed the spam filters because the
sending address was on the recipient’s organizational approved-senders list as
noted by
(org good) . The entry [db-null] indicates the recipient doesn’t have
any user-level approved senders.
X-pstn-addresses: from [email protected] forward (org good) [db-
null]
The X-pstn-addresses header field does not appear if the message was sent to
multiple users of the message service.
