I'm having a problem with this approach. It isn't changing the
Content-Type.
Here's how I have it set up:
I do the Spamassassin checks in filter_begin(), straight from the
MIMEdefang Tips page on RoaringPenguin, with slight changes:
sub filter_begin {
# drop messages with suspicious characters
if ($SuspiciousCharsInHeaders || $SuspiciousCharsInBody) {
..... code from tips page ....
}
# Spamassasin checks
$foundSpam = "no";
if ((-s "./INPUTMSG") <= (50 * 1024)) {
my($hits, $req, $names, $report) = spam_assassin_check();
if ($hits >= $req) {
action_add_header("X-Spam-Detect", "HIGH");
action_add_header("X-Spam-Status", "Yes, hits=$hits required=$req");
$foundSpam = "yes";
} else {
action_add_header("X-Spam-Status", "No, hits=$hits required=$req");
}
action_add_header("X-Spam-Report", "$report");
}
}
Then in filter(), after the code from the Tips page that strips out
dangerous attachments, I add these statements:
if ($foundSpam eq "yes") {
if ($type eq "text/html") {
$entity->head->mime_attr("content-type" => "text/plain");
}
}
return_action_accept();
And then filter() ends. Problem is, text/html spam still comes through as
text/html. It is not converted to text/plain as Spamassassin alone can do.
What am I missing? It's probably a dumb perl mistake. I'm not very good
at perl yet. I am wondering if the scope of my variable $foundSpam as set
in filter_begin() isn't what I think it is, and the "yes" value is not seen
inside filter().
