When you have configured WorkgroupMail in this way, an SMTP server will be setup to listen on the external interface for new e-mail, either from your ISP or directly from the sender's ISP, if you host your own mail.
Note that you will not be able to make use of the Junk mail filtering or the maximum message size download option if you receive mail using SMTP, since both these features require POP3 in order to function.
