使用 csv 文件过滤结果

Question

基本上，我有一个扫描邮件跟踪日志的脚本，它每 15 分钟检查一次日志的最后一小时，在短时间内查找大量电子邮件。我知道如何使用 -gt 和 -notlike 进行过滤，但我希望脚本检查 csv 中我想要过滤的值。例如，有些人我们希望在短时间内发送大量电子邮件，我需要一个 csv 例外列表。

$ErrorActionPreference = "silentlycontinue"
add-pssnapin Microsoft.Exchange.Management.PowerShell.E2007
add-pssnapin Microsoft.Exchange.Management.PowerShell.Admin

$Now= Get-Date
$start= $Now.AddHours(-1)
#$end= $Now.AddHours(-1)

$Senders = ("bumailhub1","bumailhub2" | Get-MessageTrackingLog -resultsize unlimited -      Start "$start" -End "$Now" -EventId SEND | Select-Object ServerHostname,EventId,RecipientCount,Sender,MessageSubject,ConnectorId | where {$_.Connectorid -eq "Outbound new (Stucheck out)"})


********Right here below is where i need it to check for a csv exceptions list, which will contain a list of email addresses that are under the column "Name", and again when creating $csvmaker


$report = $senders | Group-Object Sender | Sort-Object Count -Descending | Where-Object {$_.Count -gt 50 -and $_.Name -NOTLIKE "MicrosoftExchange*"} | Select-object Count, Name
$mailing1 = $report | ConvertTo-HTML | Set-Content c:\TEMP\Date_$((get-date).tostring("MMddyyyy"))_Time_$((get-date).tostring("HHmmss"))_Users_Over_100PERLast2Hour.htm

$exceptions = Import-Csv C:\TEMP\CSVS\Exceptions\Exceptions.csv

$csvmaker = $senders | Group-Object Sender | Sort-Object Count -Descending | Where-Object {$_.Count -gt 100 -and $_.Name -NOTLIKE "MicrosoftExchange*"} | Select-object Count, Name
$csvmade =  $csvmaker | ConvertTo-CSV | Set-Content c:\TEMP\CSVS\Users_Over_100PERLast2Hour.csv

$mailing1
$mailing2 = $report | ConvertTo-Html
$subjectreport = $senders | Group-Object MessageSubject | Sort-Object Count -Descending | Where-Object {$_.Count -gt 50 -and $_.Name -NOTLIKE "MicrosoftExchange*"} | Select-object Count, Name
$subjectreportemail = $subjectreport | ConvertTo-Html

$head = Get-Content C:\TEMP\files\head.htm
$report1 = Get-Content C:\TEMP\files\report1.htm
$report2 = Get-Content C:\TEMP\files\report2.htm

If ($report | Where-Object {$_.Count -gt 100})
{

只需从一个简单的文本文件中读取这些发件人：

$whitelistedSenders = Get-Content 'C:\path\to\sender_whitelist.txt'

如果您必须使用 CSV，请仅提取发件人姓名列的值：

$whitelistedSenders = Import-Csv 'C:\path\to\sender_whitelist.csv' `
  | % { $_.'Sender Name' }

然后只处理那些不在白名单中的发件人：

$subjectreport = $senders `
  | ? { $whitlistedSenders -notcontains $_.Name } `
  | Group-Object MessageSubject `
  | Sort-Object Count -Descending `
  | ? { $_.Count -gt 50 -and $_.Name -notlike "MicrosoftExchange*" } `
  | select Count, Name
