POPcon PRO™ connects your MS Exchange Server to your POP3 and IMAP mailboxes. It contains all of the features of the POPcon Standard version plus the antivirus, antispam and rule-based distribution functions.

POPcon PRO downloads the emails from POP3, POP3-SSL, IMAP and IMAP-SSL mailboxes and distributes them to exchange or domino mailboxes according to the recipient information found in the mail headers.

The software runs as a background service under any .NET 4.7.2-compatible Windows Server version (Windows 2022, Windows 2019, Windows 2016, 2012) or even normal Windows workstations (Windows 10, 8, 7).

POPcon PRO checks each incoming email with its built-in antivirus scanner. Emails that contain viruses are encapsulated in a warning message and can be diverted to the postmaster. Antivirus signatures are automatically updated daily. POPcon PRO also includes anti-spam measures.

POPcon PRO Features


Mail flow of incoming emails with POPcon PRO

How email is routed with POPcon PRO

The mail sender transmits emails via the SMTP-protocol directly (or over an additional smtp relay server) to your POP3 or IMAP mailbox at your provider. POPcon periodically connects to your POP3/IMAP mailboxes, downloads the email using the POP3 protocol or the newer IMAP protocol (with and without SSL) and stores the messages in temporary files. After downloading emails from all your mailboxes, POPcon connects to your Exchange Server and sends the previously downloaded emails via the SMTP protocol directly to your Exchange users.

Mail flow of outgoing emails with POPcon PRO

POPcon is only used for incoming emails. Outgoing mail traffic is handled directly by your Exchange Server.
