问：如何用powershell发邮件？
答：
Send-MailMessage   -Subject "主题"       `
-From  "你的hotmail账户@hotmail.com"   -To  "你的qq邮箱@qq.com"   `
-SmtpServer   "smtp.live.com"  -Port 587  -UseSsl    -Credential  "你的hotmail账户@hotmail.com"  `
-Attachments $附件 -BodyAsHTML -body $HTML邮件内容

注意：
1 用xxx@QQ.com + 你的qq密码 + 上述命令 发邮件是不行的。因为为了qq密码安全，腾讯要求独立的邮箱密码。  
2 从qq邮箱发件，默认也不行。被关了，需要在设置中开启smtp。
3 powershell 3.0 和 以上 才支持port参数。对于win7，你需要先安装ps最新版

我的代码：

# 简单版
Send-MailMessage   -Subject "powershell send Email"       `
-From  "taozXX@hotmail.com"   -To  "3845XX@qq.com"   `
-SmtpServer   "smtp.live.com"  -Port 587  -UseSsl    -Credential  "taozXX@hotmail.com"  `
-BodyAsHTML -body "powershell send Email from taozXX@hotmail.com to 3845XX@qq.com"
#弹出密码框，填写hotmail密码
#-SmtpServer   "smtp.office365.com"  -Port 587  -UseSsl    -Credential  "taozXXX@hotmail.com" `

# 函数版，并且加了安全机制
# Write-Output 不要随便用，会有管道传递，Write-Host功能少，只是简单打印
