Pop3Connector is designed to download mails from an unlimited number of POP3 mailboxes and relay them to any SMTP server, for instance Exchange Server, GMail, or any other mail server using the SMTP protocol. Initially designed as a replacement of the standard POP3 plugin that comes with Microsoft's Small Business Server (with all its limitations), Pop3Connector has some features that are hard to find anywhere else, and comes at an unbeatable price.
