IIS 7 + Windows Server 2008 - Sending Emails from Classic ASP using CDO - iis-7

Question

On our existing platform we decided to upgrade our development server from Windows Server 2003 to 2008 some time ago.
The problem we are facing is that all asp scripts that used to send emails before when we had Windows Server 2003 worked. Now, they stopped working with no error on page or on the SMTP logs.
If I use telnet to send an email manually works fine.
But it's not working from our classic asp scripts.
This is our ASP code
Sub SendEmail(fromEmail, toEmail, ccEmail, bccEmail, subject, body, somefiles)
Set m_Mailer = Server.CreateObject("CDO.Message")
With m_Mailer.Configuration.Fields
.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 1
.Item("http://schemas.microsoft.com/cdo/configuration/smptserver") = Request.ServerVariables("server_name")
.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverpickupdirectory")=SMTP_SERVER_PICKUP_DIRECTORY
.Update
End With
If m_CharacterSet <> "" Then
m_Mailer.BodyPart.Charset = m_CharacterSet
End If
m_Mailer.To = toEmail
m_Mailer.CC = ccEmail
m_Mailer.BCC = bccEmail
m_Mailer.From = fromEmail
m_Mailer.ReplyTo = fromEmail
m_Mailer.Subject = subject
If m_UseHtmlFormat Then
m_Mailer.HTMLBody = FixText(body)
Else
m_Mailer.TextBody = FixText(body)
End If
Dim i
somefiles = Split(somefiles, vbTab)
For i = 0 to UBound(somefiles)
m_Mailer.AddAttachment(somefiles(i))
Next
m_Mailer.Send
End Sub
I've checked permissions on the mailroot folder and the IIS user has full control. I've already set the relay to 127.0.0.1, and gave the IIS User access to the smtp as well.
When I use telnet I get everything on the log and receive the email correctly.
But even when using this test script I don't get any email, they stay stuck on the pickup folder
Dim emailer
Set emailer = New EmailHelper
emailer.SendEmail "test#test.com", "fede#shocklogic.com", "", "", "Test 1 2 3 from " & Request.ServerVariables("HTTP_HOST"), "Test...", ""
Set emailer = Nothing
Response.Write "DONE"
When I try to execute this test script I always get "DONE" on the page, but no email.
SMTP is already installed and enabled.
Any help would be great

Found the solution! (At least it works for me)
I removed this line
.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverpickupdirectory")=SMTP_SERVER_PICKUP_DIRECTORY
And configured SMTP in IIS 7 console to use localhost instead of pickup directory and works perfect now!
