Can't access mail.yahoo.com

[pdk68]

So I have a customer who has a 506E in place and his DNS servers are behind it and I have them staticly mapped as follows;

static (inside,outside) tcp X.X.X.2 domain Y.Y.Y.2 domain netmask 255.255.255.255 0 0
static (inside,outside) tcp X.X.X.3 domain Y.Y.Y.3 domain netmask 255.255.255.255 0 0
static (inside,outside) udp X.X.X.2 domain Y.Y.Y.2 domain netmask 255.255.255.255 0 0
static (inside,outside) udp X.X.X.3 domain Y.Y.Y.3 domain netmask 255.255.255.255 0 0

access-list is as follows;

access-list 103 permit tcp any host X.X.X.2 eq domain
access-list 103 permit tcp any host X.X.X.3 eq domain
access-list 103 permit udp any host X.X.X.2 eq domain
access-list 103 permit udp any host X.X.X.3 eq domain

Everything works great except when I try to access yahoo mail. Anyone else had this problem and if so what is the fix. I am having no luck searching Cisco's site and I didn't see another post on here with this problem.

Thanks

HI.

Maybe you don't have a reverse lookup PTR entry on your ISP DNS servers:
