MailMessage.Clear;
MailMessage.From.Address := mEmail;
MailMessage.From.Name := mNombre;
MailMessage.Recipients.EMailAddresses := DM.Query12EMAIL.Text; {destino}
MailMessage.BCCList.add.Address := mEmail;
MailMessage.Subject := Edit10.text;
MailMessage.Body.Text := Memo1.Text;

f FileExists(Edit2.Text) then
TIdAttachment.Create(MailMessage.MessageParts,Edit2.text);

Con Indy9 me funciona.
