[feat] Any way to filter attachment types, sieve?

I tried to filter some attachment type using sieve (raw body or mime) but no success.
Are there limits in sieve on Forwardemail, so the message is not fully analyzed?
If you know sone working way to filter .zip .img .rar .7z .exe and so on, please post them here, thanks.

The issue names no files, tests, or entry points. Start by checking the project's Sieve support and MIME or attachment handling to determine whether filtering .zip, .img, .rar, .7z, and .exe is supported. Done would be a reproducible filtering method or a clearly scoped implementation request.
