MailIt Function:

The MailIt function sends an email message to a recipient. MailIt returns True if the mail is sent successfully and False if the mail is not sent for any reason. MailIt supports sending email via two COM objects available on most servers. There are five required arguments: classstring, mailto, mailfrom, mailsubject, and mailbody.

Argument Expects
ClassString Acceptable values are "jmail.smtpmail" or "cdonts.newmail"
MailTo Valid EMail address as string
MailFrom Valid Email address as string
MailSubject Subject text as string
MailBody Body text as string


Syntax:
boolean = MailIt(classstring, mailto, mailfrom, mailsubject, mailbody)
Example Usage:
Use MailIt to send an email with the jmail.smtpmail object. 
<%
Const UseJmail = "jmail.smtpmail"
Dim boolSent

boolSent = MailIt(UseJmail, "to@to.com", _
		"from@from.com", "mail subject line", "mail body text")
If boolSent Then
	Response.Write "Mail Sent Successfully!"
