Frequently Asked Question

Choosing the right protocol is critical for mailbox synchronization and data integrity:

• IMAP (Internet Message Access Protocol): The modern standard. It syncs directly with the server, ensuring that actions (like "Read" or "Sent") reflect across all devices. Use Port 993 (SSL/TLS) for secure incoming mail.
• POP3 (Post Office Protocol): Best for single-device use with limited server storage. It downloads mail locally and often deletes the server copy. Use Port 995 (SSL/TLS).
• SMTP: For outgoing mail, use Port 587 (STARTTLS) to ensure high deliverability and modern encryption standards.
