Add Reply-To Email to WFFM Send Email Message Save Action

Question

I'm attempting to add a reply-to address to an email I'm sending via WFFM 8.1. The save action I am using is "Send Email Message." The email being sent includes the email address of the user filling out the associated form. I would like to use the user's email as the reply-to address. In the email message editor, I do not see a reply-to email option so I assume I will need to write a custom save action. My question is twofold:

1. Is it possible to add a reply-to address to the "Send Email Message" save action with out-of-the-box WFFM?
2. If this functionality is not available out-of-the-box, it possible to extend the functionality of the "Send Email Message" save action to include a reply-to email while preserving the following UI that accompanies the save action?

Thanks for the help!

Answer 1

You need to override for the SendEmail method in the processMessage pipeline (patched in the /App_config/Include/Sitecore.Forms.Config)

With something like this:

using Sitecore.Form.Core.Pipelines.ProcessMessage;
using System.Net.Mail;

namespace Arktouros
{
    public class PressMessageOverride
    {
        public void SendEmail(ProcessMessageArgs args)
        {
            SmtpClient smtpClient = new SmtpClient(args.Host);
            smtpClient.EnableSsl = args.EnableSsl;
            if (args.Port != 0)
            {
                smtpClient.Port = args.Port;
            }
            smtpClient.Credentials = args.Credentials;
            smtpClient.Send(this.GetMail(args));
        }

        private MailMessage GetMail(ProcessMessageArgs args)
        {
            MailMessage mail = new MailMessage(args.From, args.To.ToString(), args.Subject.ToString(), args.Mail.ToString())
            {
                IsBodyHtml = args.IsBodyHtml
            };
            //your reply to goes here, set to be the from address of the form being submitted
            mail.ReplyToList.Add(new MailAddress(args.From));

            if (args.CC.Length > 0)
            {
                mail.CC.Add(args.CC.ToString());
            }
            if (args.BCC.Length > 0)
            {
                mail.Bcc.Add(args.BCC.ToString());
            }
            args.Attachments.ForEach(delegate (Attachment attachment)
            {
                mail.Attachments.Add(attachment);
            });
            return mail;
        }
    }
}

then update the config file to point to your new class:

replace: <processor type="Sitecore.Form.Core.Pipelines.ProcessMessage.ProcessMessage, Sitecore.Forms.Core" method="SendEmail" />

with

<processor type="NamespaceOfYourClass, YourDLL" method="SendEmail" />

and away you go, for info this is not fully tested, but should work fine.
