problem with mail.yahoo.com

Hi! I have a problem. I am using SuSE 7.0 as a proxy server. I am using squid2.2 stable5. My problem is that all my clients can't connect to a site, specifically: mail.yahoo.com, properly though other sites seems ok. I have already observed the cache logs and messages log but I find no odd things to make some conclusions. My server works find until this problem appeared and I cant seem to find out way. I have already replace my squid.conf file with a working backup but still no luck. Can anyone help me with this? I need to solve this fast. tnx in advanced.
