Export message to the text file can corrupt original structure, and as you
note, does not work with MIME attachments or HTML messages. Proposed filter
should be more complex and use a little different operations:
1. Export message to the file in Unix mailbox format
2. Modify the header in exported Unix message and use this modified file as
the source in exporting message again, but to another text file
3. Import the message from text file, delete this file and the Unix message
file
4. Send modified message and delete original one (optional)
Assuming the Unix message will be exported to "C:\Unix_Msg.txt", and the
second export file will be named "C:\export.msg", the filter template for
this export used in second operation will be following:
--------------- [ Export template ] ------------------
%_OldMsg(%Put="C:\Unix_Msg.txt")%-
%SetPattRegExp="(?ismU)(.*)(^Resent-From:.*\s*.*\n)(\w.*?)"%RegexpBlindMatch(%_OldMsg)%-
%Subpatt(1)%Subpatt(3)
%SetPattRegExp="(?ism)\n\n(.*)"%RegexpMatch(%_OldMsg)%-
--------------- [ End of template ] ------------------
Empty line in the template is mandatory, because it must separate message
header and message body.
You can make many things using such trick, e.g., repair threads, use HTML
templates, modify different parts of message or even substitute or delete
attachments.
