## How to Set Up a 10/10 Mail Server Guide
|
|
Check out the [Complete Setup Guide](https://github.com/r-raymond/nixos-mailserver/wiki/A-Complete-Setup-Guide) in the project's wiki.
|
|
|
|
## How to Backup
|
|
|
|
Checkout the [Complete Backup Guide](https://github.com/r-raymond/nixos-mailserver/wiki/A-Complete-Backup-Guide). Backups are easy with `SNM`.
|
|
|
|
## How to Test for Development
|
|
|
|
You can test the setup via `nixops`. After installation, do
|
|
|
|
```
|
|
nixops create nixops/single-server.nix nixops/vbox.nix -d mail
|
|
nixops deploy -d mail
|
|
nixops info -d mail
|
|
```
|
|
|
|
You can then test the server via e.g. `telnet`. To log into it, use
|
|
|
|
```
|
|
nixops ssh -d mail mailserver
|
|
```
|
|
|
|
To test imap manually use
|
|
|
|
```
|
|
openssl s_client -host mail.example.com -port 143 -starttls imap
|
|
```
|
