I am new to Umbraco, using 4.5, MySQL and have installed the CultivContactForm package and it works well except the FROM address (stored as _contactEmail) is not doing what I wanted. The email address users enter in on the site must be the same as the mail account the smtp is connected to. Otherwise this error is received:

System.Net.Mail.SmtpFailedRecipientException: Mailbox name not allowed. The server response was: 5.7.1 <[email protected]>: Sender address rejected: not logged in

I thought I'd edit somewhere within the cultivContactForm.ascx file, perhaps here:

           <asp:TextBox runat="server" ID="_contactEmail" class="inputString"></asp:TextBox>
            <asp:Label ID="_emailLabel" class="formLabel" runat="server" Text="Label"></asp:Label>

I want users to be able to submit their own email address, but can't seem to find anywhere I can edit in the package to make this happen. The .dll is there, but I can't get inside it to make changes.

Any ideas please on how to tweak so they can add their address, and how can I get inside the .dll? (thanks in advance)
