# Email Client Configuration
## Overview
This guide explains how to connect your preferred email client or mobile device using IMAP, POP3, or Exchange ActiveSync (EAS).
**We recommend IMAP for most users** — it provides two-way synchronization and keeps all messages and folders stored on the server, accessible from any device.
> ⚠️ For security reasons, non-encrypted mail ports are not supported. Please use SSL/TLS or STARTTLS connections only.
