[squid-users] msn messenger login issue

I have configured squid-2.6 and Dansguardian 2.10.0.3 on RHEL5 for caching
and web filtering for my office internet users. i m facing problems in
loging into msn messenger, i have put acls in squid and msn ips in
dansguardian exceptionsite list but still not getting msn messenger login,
my squid acls for allowing msn messenger and dansguardian exceptionsite list
is as under.

Squid Acls (there is no acl in my squid.conf to block msn msgr)

acl msn_mime req_mime_type -i ^application/x-msn-messenger$
acl msn_gw url_regex -i gateway.dll
acl msnd dstdomain messenger.msn.com gateway.messenger.hotmail.com
http_access allow msn_mime
http_access allow msn_gw
http_access allow msnd

DG exceptionsitelist
64.4.13.0/24
152.163.241.0/24
64.12.163.0/24
207.46.110.0/24
207.46.1.0/24
65.54.0.0/16
207.46.104.20
207.46.110.0
65.55.149.121

64.4.32.7
221.120.250.106
65.242.27.35
64.4.9.254

After doing all this i m still facing login issues with msn messenger
whenever i try to login it shows error login failed, service temporarily
unavailable, i have juniper firewall behind proxy which has any any policy
for proxy server, proxy servers iptables are fine, transparent proxy
disabled due to DG,

here are my squid logs while i try to log into msn messenger
