SAS supports three types
of protocols: MAPI (such as Microsoft Exchange), Vendor Independent
Mail (VIM—such as Lotus Notes) and SMTP. The default value
is MAPI. If you specify SMTP, you must also specify and configure
the EMAILHOST and EMAILPORT system options. SMTP is available only
when you are sending e-mail programmatically. SMTP is not available
using either your e-mail program native dialog box or the SAS e-mail
dialog box.
