答え1

この問題は送信コネクタの障害によって発生する可能性があると指摘する人もいます。新しいコネクタを作成すると、問題が解決する場合があります。

http://www.networkadminsecrets.com/2010/04/421-and-451-exchange-2007-errors.htmlこれを実行するための Powershell スクリプトが提供されます:

New-SendConnector -Name ForceHelo -AddressSpaces problemdomain.com -ForceHELO $true

Exchange 2007 向けに提案されているが、2010 でも試してみる価値があるかもしれない別の解決策は、ネットワーク インターフェイスの自動チューニングを無効にすることです。

netsh interface tcp set global autotuninglevel=disabled
