Last time, we talked about blogs. Now I want to talk about the mail system.
This time, I’m using a project from another awesome developer. If I’ve made any mistakes, feel free to point them out!

1. Register and log in to a CF (Cloudflare) account (After registering, you don’t need to verify your email immediately, that’s done later.)
   
   
2. Bind your domain name
   2.1 Open your domain and go to Overview
   
   
   
   2.2 Bind the domain
   
   
   
   Click “Add Site.” Still use ns binding.
3. Deploying the mail system
   Open GitHub - maillab/cloud-mail: A Cloudflare-based email service | 基于 Cloudflare 的邮箱服务 | Cloudflare Email 邮箱 Mail · GitHub
   Fork it to your account
   Open Cloudflare Workers and Pages
   
   
   
   Click “Create Application”
   
   
   
   Then choose GitHub
   
   
   
   Select the project you just forked
   
   
   
   Change the build branch to mail-worker
   
   
   
   Click “Deploy”
   
   
   
   Then add the variable: admin, a text variable
   For example, if your domain is a.a (an email, suffix is the domain you just bound), the value can be [email protected] or [email protected] — the prefix is up to you.
   Add variable: domain, a JSON variable
   Write it like this: [“a.a”]. This domain must have the suffix you used for the admin above and must be bound to Cloudflare.
   Add variable: jwt_secret (text variable).
   Type any string you like, as long as others don’t know it.
4. Buckets
   4.1 kv
   Open Storage & Buckets – Worker KV
   
   
   
   Go to the KV creation page
   
   
   
   Create a KV called cloud-mail
   
   
   
   4.2 d1
   Open Storage & Buckets – D1 SQLite Database
   
   
   
   Go to the creation page
   
   
   
   Create a bucket called cloud-mail (I’ve already created one, so mine wasn’t successful)
   
   
5. Brief miscellaneous settings
   Go back to Workers, click “Bindings,” and bind KV and D1 as kv and db.
   
   
   
   Then go to Computing – Email Services – Email Routing
   
   
   
   Add all the domains you wrote in domain
   Then do this for each domain: go in and set routing rules
   
   
   
   Change the “catch-all” rule to “Send to worker-cloudmail storage” and that’s it
   
   
   
   Then go to Workers and bind to the URL you want (e.g. mail.a.a)
   Then open (the URL you just bound)/api/init/(the jwt_secret you set)
   Wait for a “success” message on the page
   Go to your URL (e.g. mail.a.a)
   Register your admin email; now you have admin rights
6. Sending outside the site
   External email sending is a bit troublesome; you need resend
   Go to resend and register
   Open domain
   
   
   
   Follow the instructions to add MX and TXT records (note: if it’s a.b.c, it’ll tell you to add send.a; just add send)
   Then go to the API page and get the key (save it)
   
   
   
   Then, in your email admin panel, go to email settings – add resend token, choose your suffix, and write down the resend API
   
   
7. Other
   The mail system also has announcements, permissions management, captcha, registration keys, etc. Feel free to explore!

TinkMail Business - Professional Email for Your Company

OquMail — Business Email

These two provide mailboxes with 5GB storage by default and offer webmail. They also support IMAP and SMTP.
Most importantly, they’re completely free and don’t require credit card verification.

You can add your own domain and create email accounts with your own domain name.

I built one before, mainly because I have countless email accounts, haha. But then the domain expired, so I didn’t mess with it anymore.

Really appreciate the expert’s tutorial!
