I'm trying to make a simple "Subscribe" and "Unsubscribe" button where a user enters their email address and the "Subscribe" button sends an email to a mailing list manager.

Protected Sub btnSubscribe_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubscribe.Click

        DotNetNuke.Services.Mail.Mail.SendMail(txtEmailAddress.Text, "stList@mydomain.org", "", "Subscribe", "subscribe List@mydomain.org", "", "", "", "", "", "")

    End Sub

I get an error saying that this is replaced by the Dotnetnuke.Services.Messaging.MessagingController  as of 5.3

When I look at other examples, I couldn't find a good way to have my module send a message FROM the address in the text box (txtEmailAddress.Text)

Any idea how to send an email with the following properties with the new Dotnetnuke.Services.Messaging.MessagingController ?

To: stList@mydomain.org
From: txtEmailAddress.text (user input)
Subject: Subscribe
Message Body: Subscribe List@mydomain.org

Thanks!

Sorry Sebastian, thanks for correcting.  OK, so it's a warning.  So now, how do I use the latest API to send a message?

I wanted to use the form and list module, but that doesn't seem to be an option because you can't change the "from" address....

All I want to do is have a text box with a "subscribe" button that sends an e-mail from the address entered into the text box to a mailing list aggregator (in SmarterMail).
