ファイルデータが汚染される問題に直面しています。 $domainの代わりに$domain_dataを試してみましたが、まだ汚染されたデータを修正することはできません。

ドメイン名（下図）を手動で転送に入れると正常に動作します。
# TRANSPORTS CONFIGURATION
userautoreply:
driver = autoreply
file = /etc/exim/domains/example.com/autoreply.info.msg
debug_print = "${local_part}@${domain}"
from = "${local_part}@${domain}"
headers = Content-Type: text/plain; charset=utf-8;\nContent-Transfer-Encoding: 8bit
subject = "${if def:h_Subject: {Autoreply: \"${rfc2047:$h_Subject:}\"} {Autoreply Message}}"
to = "${sender_address}"
exexの設定は次のとおりです。

私はlocal_partが汚染されていると考えています。 ${local_part}を${local_part_data}に置き換える必要があります。
