>>i have setup an A record on my web server and a MX record.<<

This sentence doesn't really make sense. What does your web server have to do with it? Nothing. Is your web server also your external DNS server?

You need an MX record in external DNS (in your case you might have only one DNS that you either host yourself or that is hosted by your ISP) that points to a host name. That host name must exist in an A record and the IP it maps to must be the IP address of your Exchange server.

Hi Marcus, the mail from: sentence should include the < > around the email address. So it should be
mail from:<marcusw@whichlist.com>

I just tested a connection to your server from the internet and it worked great.

thanks for your help, it seems that maybe it took some time for the mx records to change as a few hours later the test started working and email started coming in
