As I'm sure you're all aware, Yahoo Groups began mangling our From: headers
last year to be from the list, not the author, because Yahoo moved to DKIM
validation.
Nice for authentication perhaps, by for me at least, immensely annoying for
reading the list and replying/attributing.
I have finally found some time to produce a workaround for this issue which I
thought other here may benefit from, especially since one form of it is a sed
script.
I've written more wordily here:
http://marc.info/?l=mutt-users&m=142006430708261&w=2
but in short:
This sed script is here:
https://bitbucket.org/cameron_simpson/css/src/tip/bin/fix-dkim-from
will under to From: header, producing a correct original author. You can use it
in a procmail recipe like this (untested, but the script itself is tested):
:0whf
* from:.*<[email protected]>
| fix-dkim-from
If you do that ahead of your filing rules, you should get good results. An
important caveat is that you should only apply the script to messages from
lists which do this mangling, hence the condition in the above rule.
Hoping others here find this useful,
