IMAP Email Migration
Copy mail and folders between IMAP accounts through your configured migration server.
Copy-only migration over verified TLS on port 993. Source messages are not deleted. IMAP does not migrate contacts, calendars or provider rules. App passwords may be required; OAuth-only accounts are not supported by this version.

What this tool does
The included service runs imapsync on an operator-managed server. Passwords are written only to restricted temporary files for the active job, then removed; raw output is not exposed to visitors. Progress and a random job token remain in memory for a limited period. Migration requires server setup, allowed IMAP hosts and a working imapsync installation. Failed jobs are reported as failures, never as completed copies.
