Imapsync is a command-line tool written in Perl that performs incremental, recursive, duplicate-free transfers between two IMAP mailboxes. It is used to migrate or back up email accounts across IMAP servers, preserving folder hierarchies and message flags.
Use cases
- migrate email from one imap server to another
- backup my imap mailbox
- transfer gmail messages to another provider
- sync two mailboxes without duplicates
- bulk migrate many email accounts
- copy emails between servers after switching hosting
When to choose
- you need incremental, resumable IMAP transfers that avoid duplicates
- you want to preserve folder hierarchy and message flags during migration
- you need a scriptable CLI or Docker-based tool for bulk mailbox migrations
- you want a mature tool with broad IMAP server compatibility
When to avoid
- you need a graphical interface for one-off transfers
- your servers only support POP3 or webmail without IMAP access
- you need two-way bidirectional sync rather than one-way transfer
- you want a fully free hosted service for mailboxes over 3 GB
