Does anyone have any particular contact info for Yahoo Postmasters? I've been getting heavy delays over the past 3-4 weeks. It appears that they are limiting my number of active connections per hour. I found some random for by searching Google Groups and submited, but I'm not very confident in any action will be taking. My company generates A LOT of mail to yahoo accounts (none spam), but I think they've flagged us as some level of spammer.
