Exchange 421 4.4.2 由于 ConnectionReset 导致连接断开

Exchange 421 4.4.2 由于 ConnectionReset 导致连接断开

我有 Exchange Server 2010,详细信息如下:

Exchange Server 2010 Microsoft Corporation 版本:14.03.0146.000

当我尝试向 Yahoo 发送一封不带附件的测试邮件时,邮件成功发送,但是当我向这封邮件添加附件时,它会在 Exchange 服务器队列中停留很长时间,有时这封邮件会在 6 到 1 天后发送给 Yahoo,有时则不会。

这是 Exchange 服务器中的错误代码:

我可以将同一封电子邮件发送到 Gmail 和 hotmail 帐户,没有任何问题。

答案1

有人认为这可能是由发送连接器故障引起的。在某些情况下,创建新的连接器可能会解决问题。

http://www.networkadminsecrets.com/2010/04/421-and-451-exchange-2007-errors.html为我们提供了执行此操作的 Powershell 脚本:

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

另一个解决方案是禁用网络接口上的自动调节,该解决方案建议用于 Exchange 2007,但可能值得在 2010 中尝试。

http://support.microsoft.com/kb/951291/en-us给出命令(从管理命令提示符运行):

netsh interface tcp set global autotuninglevel=disabled
