Live.comメール サードパーティメールソフトのメールヘッダを勝手に削除する独自仕様を導入？
【期間限定ネタ】Windows 10 環境での Outlook.com / Gmail と Office Outlook 2013 / Mozilla Thunderbird - 脳脂肪のパクリメモ
「どなたか検証のお願い」メールクライアントからの送信メールでBCC宛に配信されない - Microsoft コミュニティ
| メールクライアント（Thunderbird、Sylpheedなど）でOutlookメール（Outlook.comじゃない）経由でメールを送信すると、BCC宛のメールが配信されないと云う事象に出会ってます。 |
どういうことだ？
という訳で試してみた

あれ…User-AgentやX-Microsoft-Original-Message-ID が飛んでる？
試しにUA偽装してみる

送信前のこの部分から赤字の個所が消えた！？
どうやら、live.com のSMTPサーバーが独自仕様で
X-Mailer
X-Mimeole
X-Microsoft-Original-Message-ID
User-Agent
などのヘッダを削除してる模様･ω･？
Bccの場合、Delivered-To ヘッダにメールアドレスが無い場合 Recpt To ヘッダから勝手に削除してる？
・ω・ もしかして、Spamメールサーバー対策？
Web Browser ならまだしも、プロトコルの独自仕様とか意味わかんないｗ
