 # mail-connect
 
-API bridge for docker-mailserver
+API bridge for docker-mailserver
+
+*mail-connect is still in early beta*
+
+## What is it
+
+mail-connect aims to connect your `docker-mailserver` to *anything* you can imagine, through the power of an API. Despite being used as a core component of LibreCloud, you can still implement mail-connect any way you wish!
+
+We provide an extendable API which interacts with the `setup` utility via a Docker socket. While this offers advantages, mail-connect is still slow on some functions (such as listing accounts), as it's merely executing pre-made commands and parsing the output.
+
+## Features
+
+All features marked with an **E** are extended features, and are not a part of the original `setup` utility.
+
+### Email
+
+- [X] Create email
+- [X] List emails
+- [ ] **E** Create email from file
+- [ ] Change password
+- [ ] Delete email
+- [ ] Restrict email
+
+### Alias
+
+- [ ] Create alias
+- [ ] List aliases
+- [ ] Delete alias
+
+### Quotas
+
+- [ ] Set quota
+- [ ] Delete quota
+
+### dovecot-master
+
+- [ ] Add
+- [ ] Update
+- [ ] Delete
+- [ ] List
+
+### Config
+
+- [ ] DKIM
+
+### Relay
+
+- [ ] Add auth
+- [ ] Add domain
+- [ ] Exclude domain
+
+### Fail2Ban
+
+- [ ] Ban IP
+- [ ] Unban IP
+- [ ] Ban log
+- [ ] Fail2Ban status
+
+### Debug
+
+- [ ] Fetchmail
+- [ ] Login
+- [ ] Show mail logs
+
+## Future Improvements
+
+I plan to implement a *much* more powerful API, when everything else has settled. I will be taking a look at the setup utility itself, and seeing how a more efficient approach can be taken.
+
+Since `docker-mailserver` is built on Dovecot and Postfix, I am confident we can improve this API to be speedy and efficient as ever.
