# Vexib Mail System - Adding Users and Configuring Mail Clients

## Overview

The Vexib mail system uses:

* Postfix for SMTP
* Dovecot for IMAP
* SMTP2GO for outbound mail relay
* mail.vexib.co.uk as the mail server

---

# Adding a New User

Example:

```
george@vexib.co.uk
```

Create the Linux user:

```bash
sudo adduser george
```

Set the password when prompted.

Verify the mailbox:

```bash
sudo ls /home/george
```

A Maildir directory should be created automatically when mail is first delivered.

---

# Sending a Test Email

From the server:

```bash
echo "Test message" | mail -s "Mailbox test" george@vexib.co.uk
```

Confirm that the message arrives.
