Yahoo email won't connect on wifi, but is fine on 3g?

[abrrymnvette]

My iphone won't connect to yahoo email on wireless, but will connect fine on 3g and my home wireless. I am at work and it just says it can't connect to the server, but if I turn wifi off, it connects just fine. I did a packet capture of it trying to connect and I see the servers resetting my connection for some reason. Anyone have any ideas? I know it's not my equipment blocking me b/c I'm the one in charge of the firewall, routers, switches.

Getting the resets from these IP's.
98.138.88.106
98.136.45.252
98.136.166.106
98.136.45.251
98.136.185.222
66.163.178.124

and a couple more.

I've deleted my profile and recreated it on my phone. Every now and then I'll get the error that it can't connect to apple.smtp.mail.yahoo.com
