Using Apache As a POP3 Server

Listen 110 <VirtualHost *:110> POP3Protocol on POP3MailDrops /usr/local/apache/pop <Directory /usr/local/apache/pop>   AuthUserFile /usr/local/apache/conf/htusers   AuthName pop3   AuthType Basic   Require valid-user </directory> </VirtualHost>

This module allows Apache 2 to act as a POP3 server. POP3 stands for Post Office Protocol, version 3, and is a commonly used protocol that allows mail clients (such as Outlook, Eudora, or Netscape Mail) to retrieve messages from a central server. Note that this module will not allow your mail reader to send messages. For that you will need a SMTP (Simple Mail Transfer Protocol) server such as Sendmail or PostFix. You enable support for POP3 by placing a POP3Protocol On directive inside the appropriate virtual host container. POP3MailDrops specifies the location of the user's mailboxes. The user Apache is running as must be able to read and write to those mailboxes.
