[Xapian-discuss] Administrivia: Problems caused by Yahoo addresses

[Rob Nagler]

Hi Eric,

Fwiw, mailman has a 'cleanse-dkim' handler which strips DKIM-related

This is insufficient. You need to rewrite the From. Looks like Mailman has
this feature now:

Olly, you'll need to upgrade to  2.1.16 to be able to turn this on.

Yahoo's change was harsh, and made everybody's list management difficult,
even for Google Groups.

It was relatively easy for us to rewrite the header so that's what we did.
AOL has similar problems, btw. We currently rewrite emails from the
following domains: google.com ebay.com paypal.com yahoo.com aol.com. FYI,
the code that does this is here:

Neat idea. Thanks for sharing. :)

IMHO: Email is still the killer app. :) What did you use to read and reply
to this? Good archival software is helpful especially with Xapian, but
we've found that the more you can do via a user's MUA, the more they'll
like your software. :)

Cheers,
