How to send an email with Day CQ Mail Service?

[Vodjakxa]

I created a component with a form. My intention is to be able to send the results of the data entered to the email, which is always written using a form. I'm trying with a servlet but it doesn't seem to detect it either

Lot of documentation available for sending email from AEM.

1. Easiest is using ACS Commons https://adobe-consulting-services.github.io/acs-aem-commons/features/e-mail/email-api/index.html
2. If just using AEM email service, you must configure Advance Network configuration and DefaultMailService. refer https://experienceleague.adobe.com/en/docs/experience-manager-65/content/sites/administering/operati...
3. For AEM onprem refer https://experienceleague.adobe.com/en/docs/experience-manager-65/content/sites/administering/operati... and https://experienceleague.adobe.com/en/docs/experience-manager-65/content/forms/administrator-help/co...
4. Make sure to follow email best practices https://experienceleague.adobe.com/en/docs/experience-manager-65/content/sites/administering/integra...

If you tried and getting specific error, can help to troubleshoot.

Hi @Vodjakxa 
try below approaches:
servlet: 

@Component(service = Servlet.class,
        property = {
                "sling.servlet.resourceTypes=project/components/content/contact-us",
                "sling.servlet.methods=" + HttpConstants.METHOD_POST,
                "sling.servlet.extensions=json"
        })
public class ContactusServlet extends SlingAllMethodsServlet {

    @Reference
    private CustomEmailService customEmailService;

    @Override
    protected void doPost(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
        String name = request.getParameter("name");
        String email = request.getParameter("email");
        String message = request.getParameter("message");

        String resourcePath = request.getResource().getPath();
        Resource resource = request.getResourceResolver().resolve(resourcePath);

        ValueMap vm = ResourceUtil.getValueMap(resource);
        String path = vm.get("path").toString();


        // Email content
        String subject = "New Contact Us Submission";
        String body = "Name: " + name + "\nEmail: " + email + "\nMessage: " + message;

        try {
            // Send email
            boolean isEmailSent = customEmailService.sendEmail(email, subject, body);

            if (isEmailSent) {
                response.sendRedirect(path + ".html");
            } else {
                response.getWriter().write("{\"status\":\"error\",\"message\":\"Failed to send email.\"}");
            }
        } catch (Exception e) {
            response.getWriter().write("{\"status\":\"error\",\"message\":\"" + e.getMessage() + "\"}");
        }

    }
}

Service:

public interface CustomEmailService {
    boolean sendEmail(String recipient, String subject, String body) throws EmailException, MessagingException;
}

ServiceImpl:

@Component(service = CustomEmailService.class, immediate = true)
public class CustomEmailServiceImpl implements CustomEmailService {
    @Override
    public boolean sendEmail(String recipient, String subject, String body) throws EmailException, MessagingException {
        final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
        Properties props = System.getProperties();
        props.setProperty("mail.smtp.host", "smtp.gmail.com");
        props.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY);
        props.setProperty("mail.smtp.socketFactory.fallback", "false");
        props.setProperty("mail.smtp.port", "465");
        props.setProperty("mail.smtp.socketFactory.port", "465");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enabled", "true");
        props.put("mail.smtp.starttls.required", "true");
        props.put("mail.smtp.ssl.protocols", "TLSv1.2");
        props.put("mail.debug", "true");
        props.put("mail.store.protocol", "pop3");
        props.put("mail.transport.protocol", "smtp");

        Session session = Session.getInstance(props, new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("abc@gmail.com","ashdkasjhdue");
            }
        });

        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("abc@gmail.com"));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipient));
        message.setSubject(subject);
        message.setText(body);
        try {
            Transport.send(message);
            return true;

        } catch (MessagingException e) {
            return false;
            //throw new RuntimeException(e);

        }




    }
}

Thank you for the  reply.

Instead in the html with the form what should I put in action?

[abhishekanand_]

you can call the servlet and pass your values params

To send an email with Day CQ Mail Service in AEM, follow these steps:
1. Configure Mail Service in AEM Go to /system/console/configuration/com.day.cq.mailer.DefaultMailService and set up SMTP settings (host, port, username, and password).
2. Create a Servlet to Send Email Create a servlet to handle form submission and send email:

package com.example.core.servlet;

import com.day.cq.mailer.Message;
import com.day.cq.mailer.MessageFactory;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.apache.sling.api.request.RequestParameter;
import javax.servlet.Servlet;

public class EmailServlet extends SlingAllMethodsServlet {
    
    protected void doPost(SlingSafeMethodsServletRequest request, SlingSafeMethodsServletResponse response) {
        String subject = request.getParameter("subject");
        String body = request.getParameter("body");
        
        Message email = MessageFactory.create();
        email.setSubject(subject);
        email.setBody(body);
        email.setTo("recipient@example.com");
        
        // Send email
        email.send();
    }
}

3. Map the Servlet to a Path Ensure the servlet is mapped to a specific path in your AEM configuration so it can be triggered by a form submission.
