Re: Exchange incoming email issue

Hi all,
Got a bit of an urgent problem here that I'm hoping someone can help with. I built an SBS 2003 R2 server a couple of weeks ago, mainly so my client could use Exchange.




I have re-created the firewalls rules, replaced the firewall/router with a different model, removed any extraneous software from the server that might ahve been causing issue (eg spybot was on there - installed by someone else) but no joy.


Does either the old or the new router have any kind of logging? If so, set it to log the port 25 forwarding rule and then get on to that nice Mr Gibson (http://grc.com) from the SBS and see a) if he finds port 25 open and b) whether your log shows the attempt. If you enable logging on another well-known port as well, such as 443, you can confirm that the scan and the logging is working.

There's no real way to confirm whether a blocked port is due to the ISP or the router, but as you have two routers that pretty well eliminates it from the suspects.

As an aside, you might point out to your client that if you are going to support their SBS, *nothing* gets installed without at least consulting you first, and also that web surfing from the server may land them with a very large bill, and probably some data and email loss when you reinstall.
