The new biz²SmtpServer – the modern alternative to the legacy Microsoft email service (IIS SMTP)
With its new product, the biz²SmtpServer, inPuncto enables direct email reception without the need for additional external services. A key driver behind its development was the discontinuation of Microsoft’s email delivery service (IIS SMTP) in modern Windows Server environments (e.g., Windows Server 2025).
The biz²SMTPServer therefore represents a powerful and future-proof alternative. Similar to the former Microsoft IIS SMTP service, inPuncto’s SMTP server acts as a local SMTP receiver.
Incoming emails are processed based on their respective recipient addresses and handled using secure authentication and protection mechanisms. The entire process runs fully automated in the background.
As a result, the inPuncto SMTP server serves as a central entry point for emails – without detours via traditional mailboxes or cloud services. Incoming messages, such as email invoices, are received directly and automatically assigned to the appropriate processes within the system.
Downstream filtering and assignment processes are no longer required. Eliminating these intermediate steps – especially in combination with the digital inbound email and document processing solution for SAP, biz²ScanServer – results in faster processing of incoming emails. The outcome is increased data throughput and overall more efficient digital invoice processing.

A powerful alternative to mailbox polling: Real-time instead of delay
Unlike traditional mailbox polling (e.g., via IMAP or POP3), where emails are retrieved at regular intervals, the biz²SmtpServer receives messages instantly upon arrival.
This provides a powerful yet simple alternative, especially for companies that do not want—or are unable—to implement OAuth2 integration, enabling direct delivery and significantly faster processes.
