Para integrar Papercut SMTP con un sistema de aplicación C#, siga estos pasos:

1. Descargue Papercut SMTP: Descargue e instale Papercut SMTP desde el sitio web oficial de Papercut .
2. Configuración: configure Papercut SMTP configurando el host y el puerto SMTP en la configuración de su aplicación. Por lo general, el puerto predeterminado es 25 o 2525.
3. Modificar la configuración SMTP en C#: Ajuste la configuración SMTP de su aplicación para que apunte a Papercut SMTP. A continuación, se muestra un ejemplo:

using System.Net;
using System.Net.Mail;

public void ConfigureSmtpClient()
{
    // Set up the SMTP client using Papercut SMTP server
    SmtpClient smtpClient = new SmtpClient("localhost", 25)
    {
        Credentials = new NetworkCredential("username", "password"), // Credentials are optional
        EnableSsl = false // Papercut doesn't support SSL connections
    };

    // Create a new email message
    MailMessage mailMessage = new MailMessage
    {
        From = new MailAddress("test@example.com"),
        Subject = "Test Email",
        Body = "This is a test email sent using Papercut SMTP.",
        IsBodyHtml = true,
    };

    // Add a recipient to the email
    mailMessage.To.Add("recipient@example.com");

    // Send the email
    smtpClient.Send(mailMessage);
    System.Console.WriteLine("Message sent successfully");
}

using System.Net;
using System.Net.Mail;

public void ConfigureSmtpClient()
{
    // Set up the SMTP client using Papercut SMTP server
    SmtpClient smtpClient = new SmtpClient("localhost", 25)
    {
        Credentials = new NetworkCredential("username", "password"), // Credentials are optional
        EnableSsl = false // Papercut doesn't support SSL connections
    };

    // Create a new email message
    MailMessage mailMessage = new MailMessage
    {
        From = new MailAddress("test@example.com"),
        Subject = "Test Email",
        Body = "This is a test email sent using Papercut SMTP.",
        IsBodyHtml = true,
    };

    // Add a recipient to the email
    mailMessage.To.Add("recipient@example.com");

    // Send the email
    smtpClient.Send(mailMessage);
    System.Console.WriteLine("Message sent successfully");
}

Ejemplo completo que combina ambos pasos

Aquí hay un ejemplo completo combinando el código de generación de PDF y enviándolo a través de correo electrónico mediante Papercut SMTP:

using System.Net;
using System.Net.Mail;
using IronPdf;

public class EmailPdfSender
{
    public void GenerateAndSendPdfEmail()
    {
        // Generate PDF
        var Renderer = new ChromePdfRenderer();
        var PDF = Renderer.RenderHtmlAsPdf("<h1>Hello World</h1><p>This is a test PDF generated by IronPDF to send as an attachment with mail using SMTP.</p>");
        string pdfPath = "test.pdf";
        PDF.SaveAs(pdfPath);
        System.Console.WriteLine("PDF Created");

        // Configure SMTP Client for Papercut
        SmtpClient smtpClient = new SmtpClient("localhost", 25)
        {
            Credentials = new NetworkCredential("username", "password"), // Credentials are optional
            EnableSsl = false // Papercut doesn't support SSL connections
        };

        // Create Mail Message
        MailMessage mailMessage = new MailMessage
        {
            From = new MailAddress("test@example.com"),

            IsBodyHtml = true,
        };
        mailMessage.To.Add("recipient@example.com");

        // Attach PDF
        Attachment attachment = new Attachment(pdfPath);
        mailMessage.Attachments.Add(attachment);

        // Send Email
        smtpClient.Send(mailMessage);
        System.Console.WriteLine("Message sent successfully with Attachment");
    }
}

using System.Net;
