Develop a NetLogic for sending emails

This NetLogic sends emails to a predefined address.

Create the NetLogic:

Project view

, right-click

NetLogic

and select

New

Runtime NetLogic

Hover-over the NetLogic, select

, and enter

EmailSender

Double-click the NetLogic.

The external code editor opens.

In the code editor, do the following:

Replace the existing code with the following code:

using System;
using System.Net.Mail;
using System.Net;
using UAManagedCore;
using FTOptix.NetLogic;

public class EmailSender : BaseNetLogic
{
    [ExportMethod]
    public void SendEmail(string replyToAddress, string mailSubject, string mailBody)
    {
        if (string.IsNullOrEmpty(replyToAddress) || mailSubject == null || mailBody == null)
        {
            Log.Error("EmailSender", "Invalid values for one or more parameters.");
            return;
        }

        var fromAddress = new MailAddress("mail@domain.com", "Name"); // Email Sender
        var toAddress = new MailAddress("mail@domain.com", "Name"); // Email Receiver
        // Password for SMTP server authentication if necessary
        const string fromPassword = "Insert your password here.";

        var smtpClient = new SmtpClient
        {
            // Fill the following lines with your SMTP server info
            Host = "smtp.domain.com",
            Port = 587,
            EnableSsl = true, // Set to true if the server requires SSL.
            DeliveryMethod = SmtpDeliveryMethod.Network,
            UseDefaultCredentials = false,
            Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
        };

        var message = new MailMessage()
        {
            // Create the message.
            Subject = mailSubject,
            Body = mailBody
        };

        // Specify the sender
        message.From = fromAddress;

        // Recipient emails
        // The MailMessage.To property is a collection of emails, so you can add different recipients using:
        // message.To.Add(new MailAddress(...));
        message.To.Add(toAddress);

        // Add reply-to address
        message.ReplyToList.Add(replyToAddress);

        try
        {
            // Send email message
            smtpClient.Send(message);
            Log.Info("Message " + mailSubject + " sent successfully.");
        }
        catch (Exception ex)
        {
            // Insert here actions to be performed in case of an error when sending an email
            Log.Error("Error while sending message " + mailSubject + ", please try again. " + ex.Message);
        }
    }
}

TIP: In the example, the email entered at run time is added to the

ReplyToList

property. This property contains a list of addresses that will be automatically added as recipients in the event of a response. The

Send

method of

SmtpClient

is encapsulated within a try/catch construct to handle possible exceptions.

Change the

var fromAddress

variable value to reflect the sender email.

Change the

var toAddress

variable value to reflect the recipient email.

TIP: In the example, the email is sent to a single recipient, but you can add more recipients by using the

property of the

MailMessage

class. See MailMessage.To Property (System.Net.Mail) | Microsoft Docs

For example:

mailMessage.To.Add(new MailAddress(...)

If needed, provide the password to the email account by modifying

const string fromPassword = "Insert your password here.";

IMPORTANT: If you use a two-factor authentication to protect your email account, you must generate a password for the application.

If needed, in the

var smtpClient

variable value, configure the

Credentials

data.

Save the code.
