如何从 powershell 将电子邮件发送到包含口音的电子邮件地址？

Question

我使用下面的代码 sn-p 从 powershell 发送 HTML 格式的电子邮件。一段时间以来，这一直没有问题，直到将一组外国用户添加到我们的环境中，其中一些新用户的电子邮件地址包含带有重音符号（á、é、í、ó、ú、ü、ñ）的字符。如何处理带有这些特殊字符的地址？

我在发送到包含 ú 的电子邮件地址时收到以下错误：

Send-HTMLFormattedEmail -to 'thisütest@domain.com' -From sender@domain.com -Subject "testemail" -XSLPath "$scriptDir\emailbodyGen.xsl"`
-Days "1" -Company 'testcompany' -Relay email.domain.com -ToDisName "Tim" -FromDisName "sender" -LogoPath "$scriptDir\logo.gif"

错误：

使用“1”参数调用“发送”的异常：“客户端或服务器仅配置为使用 ASCII 的电子邮件地址 本地部分：thisütest@domain.com。” 在 C:\test\Untitled1.ps1:150 char:9 + $Client.Send($Message) + ~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : SmtpException

代码：

MailAddress 有一个允许您指定编码的 ctor，请参见此处：https://msdn.microsoft.com/en-us/library/f52hswkf%28v=vs.110%29.aspx
