It's a typo, I presume? In my example, u...@domain.com wants the boilerplate
and u...@domain.org doesn't. So I guess you meant "resend to u...@domain.com,
delete_recipient(u...@domain.org) and add boilerplate", right?
The man page says to call this function (resend_message) in either
filter_begin() or filter_end(). The *boilerplate* functions can only be called
in filter_end().
I haven't tried it yet but would it look something like this pseudo-code below?
sub filter_end() {
@want_boilerplate = get_recipients_with_boilerplate_from(@Recipients);
@dont_want_boilerplate = get_recipients_without_boilerplate_from(@Recipients);
if (scalar(@dont_want_boilerplate) > 0 && resend_message(@want_boilerplate)) {
foreach $recip (@dont_want_boilerplate) {
delete_recipient($recip);
}
append_text_boilerplate();
append_html_boilerplate();
}
[continue with other filtering code in this function...]
Sorry if I only have a vague idea of how the mimedefang filtering process works
but I don't know if the new ORIGINAL message created by resend_message will
also go through the filter_begin(), filter() and filter_end() functions again.
That's because I have other filtering needs in those functions not just
appending a boilerplate (such as virus scanning, etc). In other words, I need
ALL messages to be processed via all filter*() functions and SOME messages sent
to specific recipients should not have a boilerplate appended. So does the
filtering process start over again with resend_message()?
Finally, I'm using Postfix 3.1.0 with mimedefang and it's working fine.
However, I'm concerned that resend_message() might not work as expected since
the man page only refers to Sendmail-specific flags.
Thanks,
Vieri

I don't use stream_by_recipient() and never have. Here's my understanding, though... If stream_by_recipient() returns false, there was only one user, so stream_by_recipient() did nothing and the filter runs as normal. If there are multiple recipients, then stream_by_recipient() resends the original message to each recipient individually, and your filter should terminate. You'll then see the new messages in separate invocations of your filter. >> Alternatively, you can do all the work yourself, and only selectively >> resend when necessary.

(but that resends immediately the ORIGINAL > message) Until a few weeks ago, yes. We were adding a header in some cases. So what we did was: if everyone wants the header, add it, and we're done. If some recipients want the header and some don't, resend the (original) message to those who *don't*, remove them with delete_recipient(), and add the header. So in your case, you would resent to u...@domain.org, delete_recipient(u...@domain.org), and then add the boilerplate. We're now doing more extensive modifications, so I have re-implemented resend_message() with my own code to modify the message as appropriate. -- Richard ___ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.

[Mimedefang] conditionally add boilerplate in message with more than one recipient
Hi, Suppose I have an email that's being sent To: u...@domain.org, u...@domain.com. @Recipients will hold both addresses. I'd like mimedefang to add a boilerplate only for the message being sent to u...@domain.com. Is that possible? If so, how? I can only add boilerplates in filter_end but not in filter_recipient. However, I can tell which is the "current" recipient being processed in filter_recipient but not in filter_end. I guess it's not designed to do this unless I somehow duplicate the message itself and add a boilerplate to one of the two.
