Hotmail\Windows Live Attachments ('download' rather than 'view online') are filtered by my proxy server because of a rule I have set. Can anyone tell me what address is actually trying to be accessed when users click on 'download' next to an attachment?

I have many hundred rules deny accessing to domain names, wildcard rules etc etc.

Thanks

very very very broad question, this could be totally off, but I'll take a swing.

I think the simplest solution would be to connect a system outside your proxy, or put in a temporary bypass rule for one host. Connect to the desired site, download the attachment, while at the same time running a command prompt command of (assuming windows here) "netstat -a | findstr ESTAB". you may need to run it a few times, keep in mind that many connections are very transient so you might miss it the first time.

you will see a list like this:
 TCP    cmt-d630:2333          216.66.8.203:http      ESTABLISHED
 TCP    cmt-d630:2338          LB140.ASHB.COTENDO.NET:http  ESTABLISHED
 TCP    cmt-d630:2339          LB140.ASHB.COTENDO.NET:http  ESTABLISHED
 TCP    cmt-d630:2341          slashdot.org:http      ESTABLISHED
 TCP    cmt-d630:2343          a96-16-83-172.deploy.akamaitechnologies.com:http  ESTABLISHED
 TCP    cmt-d630:2346          a96-16-83-172.deploy.akamaitechnologies.com:http  ESTABLISHED

(ignore all of the connections to localhost, those aren't likely to be part of your problem)

look thru the list of connections that your download session spawned (not just host names but ports too, maybe its a weird port or ftp or something), then compare this list to your log in your proxy. You should be logging everything getting blocked, so you should see something in your block list that matches your netstat output, and that will be your culprit.

If you don't see anything in your proxy log, then it's probably a firewall rule blocking something. Use the same log review process and you'll find your culprit.
