Email workers send email

Hello im trying to send an email within the email woker. I tried this:

import { EmailMessage } from "cloudflare:email";
import { createMimeMessage } from "mimetext";

export default {
    async fetch(request, env, ctx) {
        return new Response('Hello World!');
    },

    async email(message, env, ctx) {
        console.log("Email received", message);
        const msg = createMimeMessage();

        msg.setSender({ name: message.from, addr: message.from});
    
        msg.setSubject("Message");
        msg.addMessage({
            contentType: 'text/plain',
            data: `${ message.raw }`
        });

        msg.setHeaders(message.headers)
     
        console.log("Msg object ready");

        var message = new EmailMessage(
          message.from,
          "[email protected]",
          msg.asRaw()
        );


          console.log("Messages ready");

        try {
          await env.SEB.send(message);
          console.log("Message sent");
        } catch (e) {
          console.error(e.message);
        }
      }
};

import { EmailMessage } from "cloudflare:email";
import { createMimeMessage } from "mimetext";

export default {
    async fetch(request, env, ctx) {
        return new Response('Hello World!');
    },

    async email(message, env, ctx) {
        console.log("Email received", message);
        const msg = createMimeMessage();

        msg.setSender({ name: message.from, addr: message.from});
    
        msg.setSubject("Message");
        msg.addMessage({
            contentType: 'text/plain',
            data: `${ message.raw }`
        });

        msg.setHeaders(message.headers)
     
        console.log("Msg object ready");

        var message = new EmailMessage(
          message.from,
          "[email protected]",
          msg.asRaw()
        );


          console.log("Messages ready");

        try {
          await env.SEB.send(message);
          console.log("Message sent");
        } catch (e) {
          console.error(e.message);
        }
      }
};

but i get the error: Cannot read properties of undefined (reading 'send'). Im not the best at JS and workers but my guess is that "SEB" is not defined or not the object i need, but i dont have any clue how to fix this. I took code from https://developers.cloudflare.com/email-routing/email-workers/send-email-workers/#example-worker and https://developers.cloudflare.com/email-routing/email-workers/reply-email-workers/

Have you configured your wrangler.toml file?

SageSphinx63920OP•10mo ago

What should be in my wrangler.toml

Alisson Acioli•10mo ago

send_email = [
    {name = "SEB"}
]

SageSphinx63920OP•10mo ago

(error) could not send email: could not send email: Unknown error: permanent error (521): 5.5.2 mail.sageee.xyz Error: bare <LF> received

Alisson Acioli•10mo ago

I am unaware of this error. Check in your Cloudflare dashboard in the Email product that you have correctly configured the correct senders. If possible, post a photo here and also post your code and your wrangler.toml here

My current code is the following:

import { EmailMessage } from "cloudflare:email";
import { createMimeMessage } from "mimetext";

export default {
    async fetch(request, env, ctx) {
        return new Response('Hello World!');
    },

    async email(message, env, ctx) {
        console.log("Email function called");    
        const msg = createMimeMessage();

        msg.setSender({ name: message.from, addr: message.to});
    
        msg.setSubject("Message");
        msg.addMessage({
            contentType: 'text/plain',
            data: `${ message.raw }`
        });

        console.log(`Message from ${message.from} to ${message.to}`)
        console.log(`Message headers: ${message.headers}`)
        console.log(`Message raw: ${message.raw}`)
        console.log(`Message raw size ${message.rawSize}`)

        var newMessage = new EmailMessage(
            message.to,
            "[email protected]",
            msg.asRaw()
          );

          console.log("Messages ready");

        try {
          await env.MAILS.send(newMessage);
          console.log("Message sent");
        } catch (e) {
          console.error(e.message);
        }
      }
};

import { EmailMessage } from "cloudflare:email";
import { createMimeMessage } from "mimetext";

export default {
    async fetch(request, env, ctx) {
        return new Response('Hello World!');
    },

    async email(message, env, ctx) {
        console.log("Email function called");    
        const msg = createMimeMessage();

        msg.setSender({ name: message.from, addr: message.to});
    
        msg.setSubject("Message");
        msg.addMessage({
            contentType: 'text/plain',
            data: `${ message.raw }`
        });

        console.log(`Message from ${message.from} to ${message.to}`)
        console.log(`Message headers: ${message.headers}`)
        console.log(`Message raw: ${message.raw}`)
        console.log(`Message raw size ${message.rawSize}`)

        var newMessage = new EmailMessage(
            message.to,
            "[email protected]",
            msg.asRaw()
          );

          console.log("Messages ready");

        try {
          await env.MAILS.send(newMessage);
          console.log("Message sent");
        } catch (e) {
          console.error(e.message);
        }
      }
};

and my wrangler is

name = "multi-forward"
main = "src/index.js"
compatibility_date = "2024-02-23"

node_compat = true

send_email = [
       {name = "MAILS"},
]

name = "multi-forward"
main = "src/index.js"
compatibility_date = "2024-02-23"

node_compat = true

send_email = [
       {name = "MAILS"},
]

I still don't know why its not working @Alisson Acioli sorry for my late response ^^ Any ideas ._. @Alisson Acioli you are my last hope :(

Alisson Acioli•10mo ago

Try change: msg.addMessage({ contentType: 'text/plain', data: ${ message.raw } }); to: msg.addMessage({ contentType: 'text/plain', data: ${message.raw}.replace(/\n/g, '\r\n') }); From the error you indicated, it seems to be something referring to a final line that is being received and could not. Also try to check the text you are sending. If the solution above doesn't work, try adding a direct text to test as data in "data": testing...

SageSphinx63920OP•10mo ago

Thats, i guess interessting

SageSphinx63920OP•10mo ago

I think the error is some kind of bug with my mail server, because changing it to som other email results in this

        msg.setSubject("Message");
        msg.addMessage({
            contentType: 'text/plain',
            data: `Testing: ${message.raw}.replace(/\n/g, '\r\n') Finished`
        });

        msg.setSubject("Message");
        msg.addMessage({
            contentType: 'text/plain',
            data: `Testing: ${message.raw}.replace(/\n/g, '\r\n') Finished`
        });

Now using this But still i sadly do not see the content of the mail

Alisson Acioli•10mo ago

Try again:

msg.addMessage({
            contentType: 'text/plain',
            data: message.raw.replace(/\n/g, '\r\n')
});

If it goes wrong, try:

msg.addMessage({
            contentType: 'text/plain',
            data: 'Testing'
});

In theory, one of the two would have to work.

SageSphinx63920OP•10mo ago

✘ [ERROR] TypeError: message.raw.replace is not a function Replace is only valid for strings and raw is a stream

Alisson Acioli•10mo ago

try 2 code

SageSphinx63920OP•10mo ago

Don't actually know how to convert a stream into string I google xd Actually i do not use js often actually i can count my js experiences on one hand

Alisson Acioli•10mo ago

Buffer.from(message.raw).toString();

SageSphinx63920OP•10mo ago

Thx <3

SageSphinx63920OP•10mo ago

After some changes i got the message.raw as string but still not the messagte content ._. https://pastebin.com/9t2gUHwG

Content of my mail was keyboard smash or "Asdvdsvdasvsd" I do not find this in the output

SageSphinx63920OP•10mo ago

And the docs say it is the email message content

SageSphinx63920OP•10mo ago

Its finally working I still do not know why my mail server does not accept these mails but as far at it works on other mails im fine with this
