You should check for failure of open, I suppose...

Looks cool so far...

Ummm... That actually looks like it will work, but it's right up there
for the most roundabout way of doing things! :-)

I believe you want:
$disclaimer_added = 0;
if (open(HDRS, "<HEADERS")) {
while(<HDRS>) {
if (/^X-Disclaimer-Added/) {
$disclaimer_added = 1;
last;
}
}
close(HDRS);
}
if (!$disclaimer_added && $RelayAddr =~ /^192\.168\.10\./) {
append_text_boilerplate($entity, $boilerplate, 0);
action_add_header('X-Disclaimer-Added', "YES");
}
However, this is unlikely to solve your problem. If someone replies to
or forwards the message, the MUA is extremely unlikely to preserve
the X-Disclaimer-Added header, and therefore the disclaimer will be
added again.
There are two reasonably reliable ways to avoid disclaimer-duplication:
1) Search the *message body* for the disclaimer text, showing tolerance for
junk like ">" at the beginning of lines.
2) Don't add disclaimers. (2) is my preferred approach. :-)

David.
