I just sent them a test email and it comes back with the error: "User is over quota". So it sounds like their Inbox is full. Here's the Whois page for them: [http://whois.domaintools.com/stanleymarket.com.hk Stanley Market Hong Kong] Maybe you can try the email addy listed there instead. There's a very useful Add-on you can consider adding to your collection called '''Flagfox'''. It adds the country's flag to the location bar when you go to a site and by right clicking that, you can check who owns the site - ''which is how I was able to give you the Whois info'' - and lots of other useful stuff. You can install it from here: [https://addons.mozilla.org/en-US/firefox/addon/flagfox/ Flagfox 4.1.1] It's been downloaded 13 million times which has to be a record I think. Sorry, forgot to answer your original question. No, you can't send an email to a fax number. EDIT: Just found these: http://www.makeuseof.com/tag/send-email-fax-machine/
