Okay, so you have one mail server which is running sendmail and it is configured to use your ISP's smarthost. By default sendmail will queue messages for up to 5 days and will keep trying to deliver them every 4 hours. Unless you have reconfigured something, it should "just work."
What files have you updated in the /etc/mail directory? Can you let us know what has been changed? c Oluwagbenga Shobowale wrote: > Thanks, but all the clients are windows and point to the local mail server > not the ISP.
