IMAP vs POP3: How to Configure Business Mail on Outlook, iPhone, and Android
Connecting your custom domain email to your personal smartphone and desktop mail client requires choosing between IMAP and POP3 protocols.
1. IMAP vs POP3 Architecture
IMAP (Recommended): Keeps all emails, folders, and read statuses synchronized in real-time across your laptop, iPad, and smartphone.
POP3: Downloads emails locally to one single device and deletes them from the server, making multi-device synchronization impossible.

993 - Outgoing SMTP Server (SSL/TLS): Port
