action_rebuild does nothing except set a flag telling MIMEDefang that
the message must be regenerated and passed back to the milter
body-replacement function.  The flag is checked when filter_end
returns,

If it needs to be visible later on in your code, then yes.

Hey

Then I dont understand the rebuild action. 

Should i then do the action_change_header and also add the header to the 
MIME::Entity?

No, not in MIMEDefang.  MIMEDefang just makes a note to ask the milter engine 
to add the header; Sendmail does the header addition just before delivery.

[Mimedefang] action_change_header

[Thomas Kristensen]

Hey

If I use action_change_header in the begining of the filter_begin, will the 
header I add/change be readable later on?
I noted the action_rebuild so my guess would be yes, but i just need to be sure 
before I go any futher on this path :)

Thanks.

[Mimedefang] action_change_header w/ multiple Subjects

[Matthew.van.Eerde]

I'd like to be able to change the subject for emails detected as spam.

I've been using
action_change_header(Subject, [SPAM] $Subject);
which has worked well until recently.

Alas, recently there have been spams that put in multiple Subject headers.  
action_change_header tags the first Subject:, but the MUA displays the second!

I'm tempted to do something like
action_delete_all_headers(Subject);
action_add_header(Subject, [SPAM] $Subject);

but I have some questions...

1) Will this work?  Or will action_delete_all_headers(Subject) repopulate the 
$Subject variable?  If so, no problem, I can shadow the variable before I call 
the action_delete_all_headers.

2) Is there a way to detect how many of a given header there are, short of 
slurping ./HEADERS?

3) Is there a way to make an action_change_all_headers()?

No; you're OK on that count.

 2) Is there a way to detect how many of a given header there are,

Not really.

 3) Is there a way to make an action_change_all_headers()?

Sure:

First, you count how many there are.  Then:

for $i (1 .. $num_headers) {
action_change_header(HeaderName, $header_value, $i);
}

David.

Yes. It works beautifully. I asked this very question not too long
ago:

http://lists.roaringpenguin.com/pipermail/mimedefang/2005-September/027960.html

I have been running in production with the proposed code I list in the
message linked above for over a month. It does exactly what I intended
it to do.

 2) Is there a way to detect how many of a given header there are,
 short of slurping ./HEADERS? 

That I don't know. I suspect looking at ./HEADERS is probably your
best course.
 
 3) Is there a way to make an action_change_all_headers()?

That I also don't know. I did not find such a function on my first
glance.
