POP3 Settings

How to get here

Note: At the top of each Services page, the name of the Service, its Status (Running or Stopped), Start/Stop and Restart button appears. This allows you to Start, Stop, or Restart individual Services from your respective web pages, as well as from the Service Administration page.

The POP3 Server lets any POP3 (Post Office Protocol, Version 3) mail client communicate with IMail Server. Supported POP3 clients include Internet Explorer, Netscape Messenger or Communicator, Eudora, Pegasus, NuPOP, Z-Mail, and UNIX mail.

POP3 clients use the "offline" method of accessing the mail server. Mail messages are delivered to the IMail Server system and the mail client periodically connects to the server and downloads the user's mail to the client system. Mail messages are automatically deleted from the server system. Therefore, mail messages are stored only temporarily on the mail server. This method of access is best suited to users who always read their mail from the same client system.

See Request for Comments (RFC) 1725 for a description of the POP3 protocol.

Important: After making changes, click Save. Stop the service, wait 5-10 seconds and restart the service.

POP3 Logging

General Options

Account Harvesting Prevention

Tip: POP3 and IMAP share the same registry settings for all Account Harvesting Prevention options. Changing an IMAP setting will also affect the POP3 setting.

SSL Settings

Note: IMail Server uses OpenSSL Command Line Tool (v0.9.8e) which supports up to 4096-bit RSA and 2048-bit DSA. OpenSSL is a cryptography toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) network protocols and related cryptography standards required by them.

Advanced Options

When logging on to POP3, the service returns a welcome message that identifies the mail server version and vendor. You can use the POP3 Advanced options to change the service's welcome message; if for example, you wanted to hide the mail server version and vendor information.

Warning: The default advanced settings should be appropriate for most installations. If you need to change these settings, be aware that they can change the operation of the server.
