我找到了这个博客站点：Adam Kahtava
我还发现了这个问题：send-mail-via-gmail-with-powershell-v2s-send-mailmessage
问题是，它们都没有满足您的需求（带密码的附件），所以我将两者结合起来并提出了这个：
$EmailTo = "myself@gmail.com"
$EmailFrom = "me@mydomain.com"
$Subject = "Test"
$Body = "Test Body"
$SMTPServer = "smtp.gmail.com"
$filenameAndPath = "C:\CDF.pdf"
$SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom,$EmailTo,$Subject,$Body)
$attachment = New-Object System.Net.Mail.Attachment($filenameAndPath)
$SMTPMessage.Attachments.Add($attachment)
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587)
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential("username", "password");
$SMTPClient.Send($SMTPMessage)
由于我喜欢为事物制作函数，并且我需要我能得到的所有练习，所以我继续写了这个：
Function Send-EMail {
Param (
[Parameter(`
Mandatory=$true)]
[String]$EmailTo,
[Parameter(`
Mandatory=$true)]
[String]$Subject,
[Parameter(`
Mandatory=$true)]
[String]$Body,
[Parameter(`
Mandatory=$true)]
[String]$EmailFrom="myself@gmail.com", #This gives a default value to the $EmailFrom command
[Parameter(`
mandatory=$false)]
[String]$attachment,
[Parameter(`
mandatory=$true)]
[String]$Password
)
$SMTPServer = "smtp.gmail.com"
$SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom,$EmailTo,$Subject,$Body)
if ($attachment -ne $null) {
$SMTPattachment = New-Object System.Net.Mail.Attachment($attachment)
$SMTPMessage.Attachments.Add($SMTPattachment)
}
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587)
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($EmailFrom.Split("@")[0], $Password);
$SMTPClient.Send($SMTPMessage)
Remove-Variable -Name SMTPClient
Remove-Variable -Name Password
} #End Function Send-EMail
要调用它，只需使用以下命令：
Send-EMail -EmailTo "Myself@gmail.com" -Body "Test Body" -Subject "Test Subject" -attachment "C:\cdf.pdf" -password "Passowrd"
我知道像这样简单地输入密码是不安全的。我会看看我是否能想出更安全的东西并在以后更新，但至少这应该能让你得到开始所需的东西。有一个伟大的一周！
