I think, a Transport Agent should not be used to mess with mails beyond
the absolutly needed at smtp level ( like Spam/virus- rejects ).
This said,
1. define a router :
autoresponder:
driver = redirect
domains = +local_domains
condition = ${if </WHATSNEEDEDTOIDENTIFYIT/>}{yes}{no}}
data = /usr/sbin/htmlremover
allow_fail
allow_defer
no_verify
no_expn
check_ancestor
unseen
more
pipe_transport = address_pipe
reply_transport = address_reply
redirect_router = autoresponder
2.
/usr/sbin/htmlremover can be a bashwrapper for java or perl / php ,
whatever you like.
Take the data delivered via stdin : ( java )
static public void main(String[] args) {
try {
BufferedReader ins = new BufferedReader(new
InputStreamReader( System.in ));
String lines = "";
String output = "";
while ((lines = ins.readLine())!=null) {
If ( line_youMayPass )
output=doWhatYouNeed(lines);
}
....
Message msg = new MimeMessage(session);
...
msg.setContent(output,contentType);
....
Transport.send(msg);
}
}
and send it to you again.. Don't forget to add a custom header, which
you use to bypass the router condition !
3. Job done, without messing in exim with your mailcontent.
