| - Sieve filters do not work with Imapsync, as they are evaluated during | ||
| LMTP delivery. Instead, Imapsync uses IMAP commands to interact directly | ||
| with Dovecot, bypassing LMTP and preventing the execution of Sieve | ||
| scripts. |

I'd add an explanation for it, something like:
Sieve filters are evaluated at the end, only on the inbox folder. The only limitation is that the "sieve_before" filter, which is used to move the email to spam, is not executed. This is intentional because spam control should be performed by the original mail server.

Considering only INBOX is the normal behavior during LMTP delivery: it is the expected behavior of the user's Sieve script. As anti-spam checks are not executed messages are not moved to Junk automatically.

I'd rather say that sieve filters are working, not matter the form you prefer: the user must be informed.
