Visendo SMTP Extender is a full POP3 server for Windows operating systems (also for Windows Server 2008, as a substitute for the missing POP3 service there). It monitors an e-mail drop folder, such as IIS "mailroot \ drop", and provides the e-mails to clients for collection via the POP3 protocol.

Visendo SMTP Extender is solving the real problem of sending and receiving emails in Windows 2008 IIS SMTP Server without the missing POP3 server. It is in fact a native POP3 Server extension for the IIS SMTP server. This allows users to access the emails received by the IIS SMTP server with any email client over the pop3 protocol.

Visendo SMTP extender is monitoring a drop folder where the IIS SMTP server or Sharepoint is saving the emails and, based on certain distribution rules, it is qualifying and routing these emails in subfolders dedicated to different email accounts. From here they can be handled with a normal email client that supports POP3 protocol (Outlook, Windows Mail, EudoraMail, Thunderbird etc.).
