Kanagesh and all, I am having the exact same problem. I'm know a little bit of how email works out on the internet, but aparently I'm missing something as to where messages are being lost in the bit bucket. Let me summarize my situation and see if that helps any smarter people help us.
I'm connected via a cable modem at comcast.net. I have a 5 computer network behind a linux router on a private 10.x.x.x network. My linux workstation (where I fetchmail my mail) is 10.1.1.101. I have tried to run a default installation of sendmail on that machine and have mutt handoff to sendmail who would try to deliver directly to the recipient. For most addresses that worked, but for others mail bounced with the message "550 cannot route to sender address". And technically that is correct... there is no route to 10.1.1.101 from the recipient's point of view. So then I tried the DSsmtp.comcast.net trick. Now about according to /var/log/maillog all my mail is "sent (OK.)", but about half of it gets lost in space without a bounce error of any sort. Can anybody help us? What is the best way to run a mail server from a non-routable ip address? -Mike Arrison On Wed, May 15, 2002 at 03:05:29PM +0530, Kanagesh wrote: > i made the change in the file sendmail.cf (DSmail.myisp.com) but when i try to send >mails > it is not being sent.
