See the mimedefang-filter(5) manpage.


GLOBAL VARIABLES SET BY MIMEDEFANG.PL
The following global variables are set by mimedefang.pl and are
available for use in your filter. All of these variables are
always available to filter_begin, filter, filter_multipart
and filter_end. In addition, some of them are available in
filter_relay, filter_sender or filter_recipient. If this is
the case, it will be noted below.

[...]

$RelayHostname
The host name of the relay. This is the name of the host
which is attempting to send e-mail to your host. May
be "undef" if the host name could not be determined.
This variable is available in filter_relay, filter_sender
and filter_recipient.

$RelayAddr
The IP address of the sending relay (as a string consisting
of four dot-separated decimal numbers.) One potential use
of $RelayAddr is to limit mailing to certain lists to
people within your organization. This variable is available
in filter_relay, filter_sender and filter_recipient.




Regards,

Kees.
