我认为您必须将UseDefaultCredentials设置为true：请参阅示例PowerShell代码

#SMTP server name
$smtpServer = "abcd.com.au"
$OFS = "`r`n`r`n"

#Creating a Mail object
$msg = new-object Net.Mail.MailMessage

#Creating SMTP server object
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$smtp.UseDefaultCredentials = $true

#Creating SMTP server object
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$smtp.UseDefaultCredentials = $true

#Email structure 
$msg.From = "abcd@abc.com.au"
$msg.ReplyTo = "abcd@abc.com.au"
$msg.To.Add("xyz@axyz.com.au")
$msg.subject = "Sample Sub (" + $a + " )"
$msg.body = "This is sample mail" + $OFS

# Attach a file 
$file = "C:\sample.txt"
$attachment = new-object System.Net.Mail.Attachment $file
$msg.Attachments.Add($file)

#Sending email 
$smtp.Send($msg)
