The A1.net email system is used primarily by regional residents and expatriates who need reliable mailbox access in the local language or through a client of their choice. This reference page documents the exact server hostnames, TCP ports, and encryption modes required to sync with A1.net from any modern IMAP, POP3, or SMTP client.
Provider-specific quirks matter here. Some regional email systems require the full email address as the username, others accept only the local part; some enforce STARTTLS on port 587, others expect implicit TLS on 465. The values documented below are the working combination for A1.net at the time of the last verification.
If you need to plug A1.net into a mail app that does not have auto-discovery for it (which is common for smaller regional providers), the block-by-block breakdown on this page gives you the exact strings to paste into each field.
Key Takeaways
- A1.Net incoming servers: POP3 at pop.a1.net (ports 110/995) and IMAP at imap.a1.net (port 993 with SSL/TLS).
- Outgoing SMTP server is smtp.a1.net, supporting ports 25, 465 (SSL), 587 (STARTTLS recommended), and 2525 (TLS alternative).
- Authentication requires full email address and password for both incoming and outgoing servers, with OAuth2 available on select clients.
- Use IMAP for real-time folder syncing across devices; POP3 is suitable for offline email with options to leave messages on the server.
- Select SMTP port based on network restrictions: 587 with STARTTLS is preferred; 465 for SSL; 2525 as a fallback; 25 often blocked.
A1.Net Server Configuration Details
A1.Net server configuration details specify the essential settings required for seamless email communication. These parameters include the incoming and outgoing server addresses, port numbers, and security protocols necessary for proper email client setup. Correctly inputting these details guarantees reliable sending and receiving of emails without interruptions.
| Setting | Value |
|---|---|
| Incoming Server (POP3) | pop.a1.net |
| Outgoing Server (SMTP) | smtp.a1.net |
| SMTP Port | 25 or 587 |
The incoming server typically uses POP3 protocol, facilitating email retrieval. SMTP handles outgoing mail with port 587, supporting secure submission. Authentication is mandatory for both servers, using the user’s full email address and password to maintain security and prevent unauthorized access.
IMAP Server Connection Details
How does one guarantee efficient email synchronization across multiple devices? The answer lies in correctly configuring the IMAP server connection details for A1.Net.
IMAP allows users to access and manage their emails directly on the server, ensuring real-time updates across smartphones, tablets, and computers. Proper setup involves using the accurate server address, port numbers, and security protocols.
Key parameters include:
- Server address: imap.a1.net
- Port: 993 (SSL/TLS enabled)
- Authentication: Requires full email address and password
- Security: SSL/TLS encryption mandatory for data protection
- Folder synchronization: Supports real-time syncing of inbox, sent, and custom folders
Correct configuration guarantees seamless email access without data loss or delay.
POP3 Server Configuration Details
While IMAP enables synchronized access to emails across multiple devices, some users prefer the simplicity of downloading messages to a single device using POP3.
POP3 is ideal for those who want to manage their emails offline and reduce server storage usage.
Configuring POP3 on A1.Net requires specific server details to guarantee proper connectivity and message retrieval.
Key POP3 server configuration details for A1.Net include:
- Server address: pop.a1.net
- Port number: 110 (non-encrypted) or 995 (SSL/TLS encrypted)
- Authentication: Required with full email address and password
- Security: SSL/TLS encryption recommended for secure transmission
- Leave messages on server: Optional setting to keep copies online or remove after download
These settings facilitate efficient and secure email download via POP3.
SMTP Server Port Configuration
Which port numbers are essential for configuring SMTP servers to send emails securely and efficiently? The SMTP server relies on specific port numbers to manage outgoing mail traffic. Correct port settings guarantee proper communication between the mail client and server while maintaining security standards.
Key SMTP port configurations include:
- Port 25: Standard SMTP port for email relay but often blocked by ISPs for outgoing mail.
- Port 465: SMTP over SSL, providing encrypted transmission for enhanced security.
- Port 587: Recommended port for SMTP submission with STARTTLS encryption.
- Port 2525: Alternative SMTP port used when others are blocked, supporting TLS.
- Port 33434: Rarely used, typically for testing or custom configurations.
Selecting the appropriate port depends on security requirements and network restrictions.

About This Guide
The A1.net email settings on this page were last verified on April 12, 2026 against the provider’s official help documentation, publicly available postmaster resources, and independent user setup reports. Email server configurations rarely change once established, most providers issue major updates only every one to two years, typically tied to phasing out unencrypted protocols or migrating to new mail infrastructure. SMTPedia re-verifies these settings quarterly and after any announced changes from A1.net. If you find a discrepancy between what is documented here and what A1.net currently requires, please report it so we can update the reference.
