About:
OfflineIMAP is a console-based program that synchronizes emails between two repositories, typically a remote IMAP server and a local Maildir folder. It allows you to read and manage your emails offline, with changes synchronized back to the server when a connection is available. This provides reliable access to your mailbox without requiring a constant internet connection.
Key Features:
  • Bidirectional synchronization between IMAP and local Maildir
  • Configurable via a simple Python configuration file
  • Supports SSL/TLS for secure connections
  • Can run as a daemon for continuous synchronization
  • Handles large mailboxes efficiently
Use Cases:
  • Reading and managing email on laptops with intermittent connectivity
  • Creating local backups of IMAP email accounts
  • Synchronizing email across multiple machines for offline access
Alternatives:
  • mbsync – Part of isync, offers more flexible mailbox formats and is generally faster
  • getmail – Primarily for mail retrieval to local Maildir/MBOX, not bidirectional sync
  • mu4e – Emacs-based email client with built-in sync capabilities, more integrated but Emacs-specific
