Probably because the docs are slightly unclear if you quick search them:
The IP address of the sending relay (as a string
four dot-separated decimal numbers.) One
potential use of
$RelayAddr is to limit mailing to certain lists to
your organization. This variable is available in
filter_sender and filter_recipient.
That doesn't say the variable is also available in filter_begin,
filter, filter_end, etc. That only becomes clear if you read the start
of that section, which says:
GLOBAL VARIABLES SET BY MIMEDEFANG.PL
The following global variables are set by mimedefang.pl and
able for use in your filter. All of these variables are
able to filter_begin, filter, filter_multipart and
addition, some of them are available in filter_relay,
filter_recipient. If this is the case, it will be noted below.
... but most people probably don't get that far.
The addition of the word "also" in some of the manpages might make
things a little clearer. Or just list all functions where the variable
is available, or say something like:
"This variable is available in filter() and the other message body
filtering functions, and also in filter_relay, filter_sender, ... [etc]"
And then define "message body filtering functions" somewhere in the
start of the section to be filter_begin, filter, filter_multipart and
(I can't recall exactly - I know I did some work on this section of
the manpage because of the introduction of read_commands_file(), could
be this is partly my fault).
