FakeSMTP configured as mail server, for more info check this


Demo | Package Install | Github


Email Modal



Fake SMTP Server

                              Fake SMTP Server intercepting emails sent to localhost on port 25


 

Configure FakeSMTP properties in AEM

                              http://localhost:4502/system/console/configMgr/com.day.cq.mailer.DefaultMailService



Solution

1) Create email template nt:file /apps/eaem-assets-send-mail/mail-templates/send-assets.html with the following code...

Subject: ${subject}

<table style="width:100%" width="100%" bgcolor="#ffffff" style="background-color:#ffffff;" border="0" cellpadding="0" cellspacing="0">
    <tr>
        <td style="width:100%">${body}</td>
    </tr>
</table>


2) Create a servlet apps.experienceaem.assets.SendMailServlet for sending emails...

package apps.experienceaem.assets;


import javax.jcr.Session;
import javax.servlet.Servlet;
import javax.servlet.ServletException;

import com.day.cq.commons.jcr.JcrConstants;

import org.apache.sling.jcr.base.util.AccessControlUtil;
import org.osgi.service.component.annotations.Component;

import org.osgi.framework.Constants;

import org.json.JSONException;

import javax.jcr.Session;
import javax.mail.internet.InternetAddress;
import java.util.*;

import java.io.IOException;

@Component(
        name = "Experience AEM Send Mail Servlet",
        immediate = true,
        service = Servlet.class,
        property = {
                "sling.servlet.methods=POST",
                "sling.servlet.paths=/bin/experience-aem/send-mail"
        }
)
public class SendMailServlet extends SlingAllMethodsServlet {
    private final Logger logger = LoggerFactory.getLogger(getClass());

    private static String EMAIL_TEMPLATE_PATH = "/apps/eaem-assets-send-mail/mail-templates/send-assets.html";

    @Reference
    private MessageGatewayService messageGatewayService;

    @Override
    protected void doPost(final SlingHttpServletRequest req,
                         final SlingHttpServletResponse resp) throws ServletException, IOException {
        ResourceResolver resourceResolver = req.getResourceResolver();

        try{
            String to = req.getParameter("./to");
            String subject = req.getParameter("./subject");
            String body = req.getParameter("./body");

            Map<String, String> emailParams = new HashMap<String,String>();

            emailParams.put("subject", subject);
            emailParams.put("body", body.replaceAll("\r\n", ""));

            sendMail(resourceResolver, emailParams, to);
        }catch(Exception e){
            logger.error("Error sending email", e);
        }
    }

    private Email sendMail(ResourceResolver resolver, Map<String, String> emailParams, String recipientEmail) throws Exception{
        MailTemplate mailTemplate = MailTemplate.create(EMAIL_TEMPLATE_PATH, resolver.adaptTo(Session.class));

        if (mailTemplate == null) {
            throw new Exception("Template missing - " + EMAIL_TEMPLATE_PATH);
        }

        Email email = mailTemplate.getEmail(StrLookup.mapLookup(emailParams), HtmlEmail.class);

        email.setTo(Collections.singleton(new InternetAddress(recipientEmail)));

        MessageGateway<Email> messageGateway = messageGatewayService.getGateway(email.getClass());

        messageGateway.send(email);

        return email;
    }
}


3) Add the action bar button Send Mail at path /apps/eaem-assets-send-mail/content/send-mail-but with following configuration...

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:granite="http://www.adobe.com/jcr/granite/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"

    sling:resourceType="granite/ui/components/coral/foundation/collection/action"
    icon="email"
    target=".cq-damadmin-admin-childpages"
    text="Send Mail"
    variant="actionBar">
    <data
        jcr:primaryType="nt:unstructured"
        text="Email sent..."/>
</jcr:root>


4) Add the send mail modal /apps/eaem-assets-send-mail/send-mail-dialog, a form with To, Subject and Body. When user selects assets and clicks on Send Mail button the modal opens with the assets paths added to content field (email body). User can add additional content before clicking Send....
