(Note: I'm not a SpamAssassin developer.)

I can confirm that this is an issue for quite a few people, and would of course
love to see a fix.

But I don't think that it's correct for a piece of software like SpamAssassin
to add specific exceptions for specific e-mail providers, that would probably
mean that SpamAssassin needs a central list of Yahoo's e-mail servers' IP
address ranges for all of Yahoo's e-mail operations.

This is therefore not so much a bug in SpamAssassin as it is a problem with
Yahoo's e-mail policies.

I would first complain to BT that "your e-mail services have a problem causing
legimitate messages to be tagged as spam all over the world", and try to get
other BT users to file similar reports. If enough customers complain that their
mail is tagged as spam, BT may either pressure Yahoo into changing their
policies, or BT may switch to another provider.

For ISPs, it's possible to turn on DKIM verification checking in SpamAssassin
and assign an appropriate negative score, but that will also increase the
amount of spam that gets through.
