1. If the bug https://github.com/stalwartlabs/sieve/issues/11 is resolved to our satisfaction, try to remove this overlay.
2. Check whether sieve-rs recieved new updates that our patch needs to be rebased upon.
3. Check whether the sieve-rs patch below that exchanges the dependency needs updates.
4. Then update the version comparison in this assert statement.
5. Update the `cargoHash` by setting it to `lib.fakeHash` and then inserting the result.
6. Check if we can get rid of alias-to-sieve when stalwart-mail has a builtin mail-forwarding feature.
