Receiving Emails

Each app has an unique email address (<app>@<domain>). You can hande incoming emails by declaring an email method:

import PostalMime from "npm:postal-mime";

export default {
    email: (msg: ReadableStream) => {
        const email = await PostalMime.parse(msg);

        console.log('Subject:', email.subject);
        console.log('HTML:', email.html);
        console.log('Text:', email.text);
    }
}

The email method receive a readable stream as it's first argument. You can use any library to parse the email content, I recommend postal-mime.

Support for sending emails is not implemented yet.

Setup

You'll need to set an MX record to start receiving emails (assuming you have already set up the wildcard DNS record for your smallweb instance):

@  IN  MX  10 mail.smallweb.run

Then, specify the smtp address when you start smallweb:

smallweb up --smtp-addr :25
