About:
Imapfilter is a command-line tool that connects to IMAP servers to process and filter email messages based on user-defined rules. It allows for sophisticated filtering logic, including matching headers, body content, and message flags. Its main value proposition is automating email organization directly on the server, keeping inboxes clean without relying on client-side rules.
Key Features:
  • Server-side filtering and processing
  • Lua-based configuration for complex rules
  • Supports multiple IMAP accounts and folders
  • Can execute external programs and manage flags
Use Cases:
  • Automatically sorting incoming newsletters and notifications into specific folders
  • Deleting or archiving spam and old messages based on age and content
  • Applying labels or flags to messages from important contacts
Alternatives:
  • procmail – Procmail filters local mail delivery, whereas Imapfilter operates on remote IMAP stores post-delivery.
  • OfflineIMAP – OfflineIMAP syncs mail locally; Imapfilter manages mail directly on the remote server.
