Delivering external POP3 email to Exchange account
One of our sites has only just been connected to our main network, so over easter I will need to join their PC to the domain. They have been using a general email address but it is just a btinternet one. Over time, hopefully we can change completely to a @schoolname.org address but for the time being they will still need to receive emails sent to the BT one. I could setup a forwarder on the BT account but not sure whether I can trust that.
So is there a way of having our Exchange server fetch the mail from that address over POP3 and deliver it to an internal mailbox? I am assuming there is since Google seemed to turn up some results, but I'm not entirely sure how to do it.
We're using Exchange 2010 SP1. Thanks :)
