Panel Backend

v1.0.113

Patch Released March 16, 2026

Email system bug fixes: rate limiting, DKIM disable, virtual domain dedup, security hardening, and improved error handling.

Per-day outgoing rate limit (outgoing_per_day) was never applied to Postfix — now correctly writes smtpd_client_connection_rate_limit to main.cf
Disabling DKIM no longer leaves stale milter settings in main.cf — added else branch to clear smtpd_milters and non_smtpd_milters
Virtual domain map now deduplicates entries between email accounts and mailing lists using a seen map
Bounce webhook endpoint is now restricted to localhost-only requests — was previously an unprotected public endpoint (Postfix runs locally)
Unsubscribe URL now uses a fallback chain: panel_url → primary_ip → server_hostname instead of hardcoded primary_ip:8443
Test email endpoint now verifies Postfix is running before attempting to send, returning a meaningful error message if not
