_INetSmtpMail Error

[antmar904]

Hello,

My script was working and stopped a couple of days ago when our SMTP server changed.  I changed the hard coded SMTP ip address with the DNS name and I'm getting the following error:

Error! Mail failed with error code 50extended error: 0

Func _SendEmail($sUser, $s_ToAddress)

    Local $s_SmtpServer = "smtp-relay.domain.internal"
    Local $s_FromName = "Report"
    Local $s_FromAddress = "do-not-reply@a.com"
    ;Local $s_ToAddress = ""
    Local $s_Subject = "Security Report"
    Local $as_Body[4]
    $as_Body[0] = "Please review the account/s listed below:" & @CRLF & @CRLF & "UserName:"
    $as_Body[1] = $sUser & @CRLF
    $as_Body[2] = "Message." & @CRLF & @CRLF & "Thank you" & @CRLF & "Team"
    $as_Body[3] = @CRLF & @CRLF & @CRLF & @CRLF & @CRLF & @CRLF & "Report created on: " & _NowDate() & " " & _NowTime() & @CRLF & "On server: " & @ComputerName & @CRLF & "Program and logs located at: " & @ScriptDir
    Local $iResponse = _INetSmtpMail($s_SmtpServer, $s_FromName, $s_FromAddress, $s_ToAddress, $s_Subject, $as_Body, "","",0)
    Local $iErr = @error
    If $iResponse = 1 Then
        _FileWriteLog($hFile, "List: " & $sUser)
        _FileWriteLog($hFile, "Mail sent: " & $s_ToAddress)
    Else
        _FileWriteLog($hFile, "Error! " & "Mail failed with error code " & @error & "extended error: " & @extended)
    EndIf

EndFunc   ;==>_SendEmail

Hi @antmar904, did you check via PowerShell or other language / tools to ensure it's related to AutoIt or a general problem?

PowerShell pseudo code (example):

# DNS / Port check
nslookup smtp-relay.domain.internal
Test-NetConnection -ComputerName smtp-relay.domain.internal -Port 25
Test-NetConnection -ComputerName smtp-relay.domain.internal -Port 587

# Send
Send-MailMessage -SmtpServer smtp-relay.domain.internal -From "do-not-reply@a.com" -To "you@domain.tld" -Subject "Test" -Body "Test" -Port 25

Maybe this helps to identify your issue.

--------

Please also provide next time the AutoIt version which you use and the OS (Win11 / Windows Server ...) for reproductive purposes.

Best regards
Sven

Thank you.

I should have posted that I did use PS to test connectivity and was successful over port 25 and also was able to successfully send a test email via PS as well.

What does this line return when you add it to your script and is the returned IP addr correct for the smtp server?:

ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : TCPNameToIP($s_SmtpServer) = ' & TCPNameToIP($s_SmtpServer ) & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console

The issue was how I formatted the email body as I was injecting extra line breaks.  Our new SMTP server was treating this a malformed data stream.

This isn't cdo but rather old fashioned cleartext SMTP without userid&password.
