Stalwart Mail Server: How to Automatically Archive SMTP Outgoing Mail Using Sieve Scripts

If you are using the modern Stalwart Mail Server, you may have noticed a classic email architecture pain point: When you send emails using clients like Thunderbird or Outlook, the sent emails dutifully reside in the “Sent” folder; however, when you configure notification bots (e.g., notification@example.com) or ERP systems to send emails automatically via the SMTP protocol, the outbox is empty. Why is this happening? This is because the standard SMTP protocol is only responsible for “transmission,” not “storage.” Desktop clients are able to save backups because they perform an additional IMAP upload operation after sending. Simple SMTP scripts usually do not perform this step.

Git IncludeIf: Elegantly Managing Multiple Git Identities

As a developer, have you ever experienced the awkwardness of accidentally committing code to a company project with your personal email? Or exposing your work email in an open-source project? If you maintain both work and personal projects, manually switching Git configurations is not only cumbersome but also prone to errors. Fortunately, Git provides a powerful and elegant solution: includeIf. This feature allows Git to automatically load different configuration files based on different conditions, completely solving the problem of multi-identity management.

PDF Content Extraction: Pdftotext vs Docling — Choosing the Right Tool for Different Scenarios

This article introduces two different PDF content extraction strategies. pdftotext offers extremely fast plain text output, making it ideal for building RAG systems and providing context for LLMs—without the need for multimodal models, making it faster and more cost-effective. Docling, on the other hand, preserves the complete document structure, formatting, and visual elements, generating human-readable content, which is perfect for document display and knowledge management systems.
