Hi ee, I have a linux server running sendmail for about 40 users. I have branch offices connected via dsl and a head office via international leased line. All my branch offices have local mail accounts on my server . This server sends mail and receives via my head office. The dns server is the ip at my head office. My problem is this, when my link goes down (head office) no mail goes out . This i understand. But even local mail doesnt get delivered. Is there anyway to make it possible for my local mail to be delivered when the link is down to my head office?
