The [smtpgw.forward] section contains the following options for relaying
messages through the application:

plicitly defines the mail server for specified domains to which the appli-
cation will send messages that should be sent to listed domains. The
values include the domain mask (special symbols "*" and "?" can be
used). and the name / IP address of the mail server the application will
connect to send email. If the default port 25 is already being used by
another application, another port number should be specified.
