Well lists.riseup.net can't either, we currently have >250k yahoo.com 
subscribers! We currently have no easy way to measure what percentage of 
messages from are _sent_ from yahoo.com addresses, but if it matches the 
percentage of subscribers that's ~7% (and my guess is senders are more 
likely to be weighted to non-freemail domains, that that might be lower).

But this is not currently a decision between

 "Support yahoo.com" vs "Not support yahoo.com"

it's a decision between

 "Allow yahoo.com posting which results in every
    yahoo/hotmail/gmail/etc address on the list bouncing and
    potentially getting unsubscribed by sympa's bounce processing"
   vs
 "Do not allow yahoo.com posting, but all non-yahoo posts still get
    delivered to yahoo/hotmail/gmail/etc addresses with no problems"

I still hope for a real solution, but we're having to pick the lesser of 
two evils purely for damage control currently :(
