'Sending SMTP mail via port 25 using CDOSYS
'This VB sample uses CDOSYS to send SMTP mail using the cdoSendUsingPort option and specifying a SMTP host.

' Note: It is recommended that all input parameters be validated when they are
' first obtained from the user or user interface.
Private Sub SendMessage(strTo As String, strFrom As String)

'Send using the Port on a SMTP server
Dim iMsg As New CDO.Message
Dim iConf As New CDO.Configuration
Dim Flds As ADODB.Fields
Dim strHTML

Set Flds = iConf.Fields

    .Item(cdoSendUsingMethod) = cdoSendUsingPort
    .Item(cdoSMTPServer) = "mail.example.com"
    'Use SSL to connect to the SMTP server:
    '.Item(cdoSMTPUseSSL) = True
    .Item(cdoSMTPConnectionTimeout) = 10
    .Update
End With

' Build HTML for message body
