mail()Postfix MTA 経由の関数を使用して、PHP で自動通知システムを作成しました。ただし、Outlook、実際には Exchange Server のユーザーは、行末に等しい「=」文字が表示され、HTML が壊れた通知を受け取ります。
Exchange Server はhtml/textを認識しましたが、「ソフト改行」または quoted-printable のデコードまたは解析に問題がありますか? この問題を解決するにはどうすればよいですか?
私が使用しているエンコーディングとスキーマは次のとおりです。
MIME-Version: 1.0
Content-Type: multipart/alternative;
boundary="8-10000000000-10000000000:87141"
