Have you tried:
strict_rfc821_envelopes = yes
? There's nothing special about a "UTF-8 BOM" (there's no such thing in
UTF-8 actually UTF-8 has no little-endian form). It is rather likely
that your sender was not using SMTPUTF8, and so the encoding of non-ASCII
envelopes is unspecified and use of such envelopes is invalid. Indeed
your Dovecot LMTP service would likely equally object to any non-ASCII
envelope.
