There are two ways to specify the SMTP configuration for sending mail.

Java system properties:	com.xmlcalabash.mail-host=hostname
	com.xmlcalabash.mail-port=portnumber
	com.xmlcalabash.mail-username=name
	com.xmlcalabash.mail-password=password
XML configuration:	<cc:sendmail host="hostname" port="portnumber" username="name" password="password"/>

If you specify a username, you must specify a password, otherwise all the properties are optional. Any unspecified properties will be defaulted by JavaMail to whatever defaults JavaMail uses.
