I just posted this in another thread, but I thought I would state it again as an FYI:

There are a lot of ISPs that have blocked us (Stardock.com) (we are working on switching our mailserver to a different one on a different ISP to resolve some of the issues). (There are a lot of unfair "SPAM" organizations that will block because one person reported a Domain, or an entire block of IP addresses as Spam)

If you do not get a response from the lookup at www.stardock.com/support you are probably being blocked.

If you email support@stardock.com and do not get a response within 2 working days (especially if you did not receive the canned reply) you are most likely being blocked.

Unfortunately, the ISPs that are blocking us typically are not sending us a returned mail, so we have no idea that the customer did not get a response.

If you do not get a response, please email the same message over again to support@stardock.com and put in the subject "I think I am being Blocked" this will then prompt us to send you a reply via Hotmail, which, even though they send more Spam then all the other ISPs combined, is Microsoft and therefore is not blocked (unless you have hotmail and are blocking all other hotmail address....but that's just another problem to deal with....)
