#region Office365RelayDependencies <# Office 365 Relay Script Simulates a local application attempting to perform one of "SMTP Client Submission"/"SMTP Relay"/"Direct Send". ###leverages Send-MailMessage to handle the email submission. ###handles validation for Input data and error handling. ###has a central repository for known errors for this submission type and provides troubleshooting suggestions. Aside from offering troubleshooting opportunities, it also grants option for customizing Email Body and Attachment. Some built in features that can be used for AntiSpam testing: ###Standard test message body with timestamp ###Gtube test ###SpamLink SafeLink URL ###Input from Console ###*.htm / HTML formatted EML from Desktop #> <# Validates Email Address via Regex #> # function Get-ValidEmailAddress([string]$EmailAddressType) # { # [string]$EmailAddress = Read-Host "Enter Valid $EmailAddressType" # if($EmailAddress -match "^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,63}$") # { # return $EmailAddress # } # else # { # Get-ValidEmailAddress($EmailAddressType) # } # } <# Validates Domain via Regex Includes a Switch purely for future extention of the script #> function Get-ValidDomain([string]$DomainType) { switch($DomainType) { "Initial *.onmicrosoft.com" { [int]$count = 0 do { Write-Host "Enter Valid $DomainType Domain Name: " -ForegroundColor Cyan -NoNewline [string]$Domain = Read-Host [bool]$valid = ($Domain -match "^[A-Z0-9]+.onmicrosoft.com$") $count++ } while (!$valid -and ($count -le 2)) if ($valid) { return $Domain } else { Write-Host "3 invalid domain inputs received`r`n ` You will be returned to the O365Troubleshooters Main Menu!" -ForegroundColor Red Start-Sleep -Seconds 3 Write-Log -function "Get-ValidDomain" -step "input address" -Description "After 3 invalid domain inputs, sending user back to O365Troubleshooters Main Menu" Exit-ScriptAndSaveLogs } } default { Write-Host "Unknown Domain Type Input Received" Get-RetryMenu } } } <# Collects a List of Valid Recipient Email Addresses: #Ask for Recipients #Provide done to end list #> function Get-Office365RelayRecipients() { $Office365RelayErrorList.Clear() [int]$Office365RelayRecipientCount = Read-Host "Enter a Number of Recipients" -ErrorAction SilentlyContinue ` -ErrorVariable +Office365RelayErrorList if( ($null -eq $Office365RelayErrorList[0]) -and ($Office365RelayRecipientCount -gt 0 ) -and ($Office365RelayRecipientCount -le 500 ) ) { [string]$EmailAddressType = "RcptTo Email Address" [int]$i = 0 while($i -lt $Office365RelayRecipientCount) { [string[]]$Office365RelayRecipients += Get-ValidEmailAddress([string]$EmailAddressType) $i++ } return $Office365RelayRecipients } else { Get-Office365RelayRecipients } } <# Collect cloud smarthost for Smtp Relay/Direct Send function, performs: -Collects Cloud Smarthost -checks Resolve-DnsName to confirm that A record is correctly propagated for it. #> function Find-O365RelaySmarthost() { $Office365RelayErrorList.Clear() [string]$DomainType = "Initial *.onmicrosoft.com" $InitialDomain = [string](Get-ValidDomain($DomainType)) $MXResolution = Resolve-DnsName -Type MX -Name $InitialDomain -ErrorAction Continue -ErrorVariable +Office365RelayErrorList if ($MXResolution.Type -eq "MX") { $Office365RelaySmarthost = Resolve-DnsName -Type A -Name $MXResolution.NameExchange -ErrorAction Continue ` -ErrorVariable +Office365RelayErrorList if ($null -eq $Office365RelayErrorList[0]) { return $Office365RelaySmarthost[0].Name } else { Get-ActionPlan("SmarthostFunctionErrors") } } else { Get-ActionPlan("SmarthostFunctionErrors") } } <# Collect Credentials function, performs : -clean-up for email address format based on Regex. -runs Powershell Connection check to validate credentials. -closes Powershell connection after confirming login works. #> function Get-AuthenticationCredentials() { $Office365RelayErrorList.Clear() $O365SenderCred = Get-Credential $O365AuthenticationCredentialsSession = New-PSSession -ConfigurationName Microsoft.Exchange ` -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $O365SenderCred ` -Authentication Basic -AllowRedirection -ErrorAction Continue -ErrorVariable +Office365RelayErrorList if ($null -eq $Office365RelayErrorList[0]) { Remove-PSSession -InstanceId $O365AuthenticationCredentialsSession.InstanceId return $O365SenderCred } else { Get-ActionPlan("AuthenticationFunctionErrors") } } <# Test-Office365RelayScriptItemPath checks for item path returns true or false (bool). #> function Test-Office365RelayScriptItemPath([string] $Office365RelayScriptFilePath) { return Test-Path $Office365RelayScriptFilePath } <# Get-MessageBody function provides: -standard test body with timestamp -Gtube test -SpamLink SafeLink URL -option to input from Console -Custom content from htm files #> function Get-MessageBody([DateTime] $d) { [string] $MessageBodyType = Read-Host "`r`nSelect a type of Message Body`r`n A : Standard test message body with timestamp B : Gtube test C : SpamLink SafeLink URL D : Input from Console E : *.htm / HTML formatted EML from Desktop Answer" switch($MessageBodyType.ToUpper()) { A { return "This is the body of test message.
