Powershell：向多个收件人发送 SMTP 消息

Question

我正在尝试向多个电子邮件地址发送电子邮件（下面的完整代码用于上下文）并不断从 powershell 收到错误消息，不确定我做错了什么，但脚本没有传递每个电子邮件地址来自变量 $expiredusers 的用户。

使用“1”个参数调用 "Send" 异常："A recipient must be specified." 在 C:\expiredreminder.ps1:33 char:5 + $smtp.Send($味精) + ~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : InvalidOperationException

Import-Module ActiveDirectory

#Set the number of days within expiration.  This will start to send the email x number of days before 
it is expired.
$DaysWithinExpiration = 7

#Set the days where the password is already expired and needs to change.
$MaxPwdAge   = (Get-ADDefaultDomainPasswordPolicy).MaxPasswordAge.Days
$expiredDate = (Get-Date).addDays(-$MaxPwdAge)

#Set the number of days until you would like to begin notifying the users.
$emailDate = (Get-Date).addDays(-($MaxPwdAge - $DaysWithinExpiration))

#Filters for all users who's password is within $date of expiration.
$ExpiredUsers = Get-ADUser -Filter {(PasswordLastSet -lt $emailDate) -and (PasswordLastSet -gt 
$expiredDate) -and (PasswordNeverExpires -eq $false) -and (Enabled -eq $true)} -Properties 
PasswordNeverExpires, PasswordLastSet, Mail | select samaccountname, PasswordLastSet, @{name = 
"DaysUntilExpired"; Expression = {$_.PasswordLastSet - $ExpiredDate | select -ExpandProperty Days}}, 
@{name = "EmailAddress"; Expression = {$_.mail}} | Sort-Object PasswordLastSet


Start-Sleep 5

Foreach ($User in $ExpiredUsers) {

$msg = new-object Net.Mail.MailMessage


$msg.From = "noreply@hdomain.com"
$msg.To.Add($User.EmailAddress)
$msg.Subject = "blah blah subject"
$msg.Body = "blah blah message text"



$smtpServer = "smtpserver.domain.com"
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$smtp.Send($msg)

}

Answer 1

您是否已验证属性 $User.EmailAddress 不为空？我不知道你是用 Get-ADUser 命令把它拉进来的，所以它没有被添加到你的邮件消息对象中。

我有一个类似的脚本，我像这样拉入所有 AD 用户：

[String[]]$samAccountNames = $(Get-ADUser -filter { Enabled -eq $TRUE -and PasswordNeverExpires -eq $FALSE -and emailAddress -like "*.com"
        } -Properties emailAddress,PasswordLastSet,PasswordExpired | 
            ?{ ($_.PassWordLastSet.AddDays(59) -lt (get-date).AddDays(7)) -or $_.PasswordExpired } | 
        sort passwordLastSet)

然后我从那里遍历 $samAccountNames 以发送有关密码过期的电子邮件。

Answer 2

听起来属性 EmailAddress 是空的..

尝试在代码中添加以下行以查看属性是否真的为空：

$user.samaccountname
$user.EmailAddress

像这样：

Foreach ($User in $ExpiredUsers) {

$msg = new-object Net.Mail.MailMessage


$msg.From = "noreply@hdomain.com"
$msg.To.Add($User.EmailAddress)
$msg.Subject = "blah blah subject"
$msg.Body = "blah blah message text"

$user.samaccountname
$user.EmailAddress



$smtpServer = "smtpserver.domain.com"
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
#$smtp.Send($msg)

}

Answer 3

代码是正确的，但我必须改进我的 OU 搜索库。搜索正在寻找没有填写电子邮件地址字段的非活动帐户，从而返回空错误。

谢谢大家
