Header Fields for Recipient Addresses

Select which email header fields POPcon analyzes to determine the recipient address when distributing catch-all emails. Check or uncheck each field as needed:

• received-for
• Delivered-To
• RESENT-TO
• X-RESENT-TO
• RCPT-TO
• To
• CC
• Envelope-To
• X-Envelope-To
• X-Original-To
• X-Apparently-To

The order of fields in the list determines the priority in which they are evaluated. Fields higher in the list take precedence.

Email Modifications

• Remove read receipts: Strips read-receipt request headers (e.g., Disposition-Notification-To) from incoming emails before delivery.
• Remove sensitivity tags: Strips sensitivity headers (e.g., Sensitivity: Private) from incoming emails before delivery.
• Remove string from start of addresses: Specify a prefix string to strip from the beginning of recipient email addresses. Useful for cleaning up addresses modified by the mail provider.

Recipient Address Handling

• Silently drop addresses: Define recipient addresses that should be silently discarded without generating a non-delivery report or notification.
• Auto-replace domains: Automatically replace the domain portion of recipient addresses. Useful when the external domain differs from the internal Exchange domain.

Network Configuration

• Local network card for external connections: Select which network interface POPcon uses for outbound connections to remote POP3/IMAP servers.
• Local network card for internal connections: Select which network interface POPcon uses for connections to the local Exchange Server.
