pmg-custom-eset is a custom antivirus integration for Proxmox Mail Gateway (PMG) using ESET's command-line scanner (cls).

Key features include:

• Integration with ESET File Security (EFS) via its CLI tool
• Configurable strict mode to allow or block encrypted/damaged archives
• Debug modes for log output and suspicious sample collection
• Self-diagnosing --selftest mode that simulates:
  • clean archive
  • EICAR test file
  • encrypted EICAR archive
• Auto-generated config file: /etc/pmg/pmg-custom-check.conf
