Narawen Inox POP3 Connector works as a bridge connecting mail servers. The software operates automatically in the background as system service. In configured time intervals it downloads e-mail messages from specified mail servers using POP3 protocol and sends them to other mail servers such as Microsoft Exchange Server or Lotus Domino using SMTP protocol. Messages are transfered as they would be delivered between servers directly. Original mail content, attachments and headers are preserved.
