 The DKIM configuration now offers two key length options: Standard (2048-bit) and Compatibility (1024-bit), balancing security with compatibility for DNS providers that impose record length limits.

Implemented automatic log rotation, gzip compression, and time-based cleanup for the Core service, significantly reducing disk usage during long-term operation.
