set mail=server.CreateObject("CDO.Message")
mail.Subject = request.form("equipo")
mail.Sender= request.form("usuario")
mail.To = "xxxxxxxxxxxxxxxxx"
mail.HTMLBody = request.form("solic") mail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2 mail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "xxxxxxx" mail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 110 mail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60
mail.Configuration.Fields.Update
mail.Send
If Err.Number <> 0 then
response.write "Error: " & err.description
Error.Clear
End If
