.NET Framework 4のメール送信機能

一時期、DocomoやauでRCFに準拠していないメールアドレスが送信できないといった問題がありましたが、.NET Framework 4のSystem.Net.Mailでは送信できるようになっているんですね。

MSDNのSystem.Net.Mail.MailAddressクラスの説明でも、「ユーザー名内の連続ドットと末尾のドット」が使用可能なメールアドレスの形式として明記されています。
http://msdn.microsoft.com/ja-jp/library/system.net.mail.mailaddress.aspx

実際にRadishというSMTP/POP3サーバを立てて試してみましたが、.NET Framework 4ではうまくいきました。（当然.NET Framework 2.0ではダメでした。）

RCFに準拠していないメールアドレスを新たに登録することは既に禁止されていますが、依然そのようなメールアドレスが残っている状態なので、日本のSIerとしては非常に助かります。
http://www.nttdocomo.co.jp/info/spam_mail/measure/change_add/
http://www.au.kddi.com/service/email/support/meiwaku/email_boshi/mail_address.html

ちなみに、SmtpClientにも変更があり、SmtpClientクラスが新たにIDisposableを実装しています。MSDNの説明を見るとFinalizeメソッドが無いのでしっかりとDisposeを呼び出してアンマネージリソースを解放する必要があるそうな。
