Setting Up Email in K-9 Mail (Android) – Firstserv Guide

This guide explains how to set up your Firstserv email account using the K-9 Mail app on an Android device.

Before You Begin

Make sure you have:

• ✅ Created your mailbox in cPanel
• ✅ Your email address and password
• ✅ Your mail server settings (if required)

Choosing Your Setup Method

There are two setup options. We recommend Option 1 where possible.

Option 1 (Recommended): Use mail.yourdomain

Example

If your domain is:

example.co.uk

Use:

mail.example.co.uk

for both:

• Incoming (IMAP) server
• Outgoing (SMTP) server

Requirements

• Your domain’s A record points to your Firstserv server
• SSL is enabled (Let’s Encrypt is issued automatically once configured)

Benefits

✅ No need to change settings if you move servers
✅ Cleaner and future-proof configuration

Option 2: Use Server Hostname

• Uses your hosting server hostname instead
• No prerequisites required

⚠️ If you change hosting providers or servers, you’ll need to update your settings.
