Message-ID: <1990Dec3.182003.15078@portia.Stanford.EDU> Date: 3 Dec 90 18:20:03 GMT Sender: news@portia.Stanford.EDU Organization: Academic Information Resources Lines: 26 Hi, I have a machine called "d31jr0" which I want to alias to the name "cumulus", because d31jr0 is such a silly mail name. The official hostname is d31jr0, but I already have an IP alias "cumulus" for this machine. I can ftp and telnet (ie use IP) from any machine in the world to "cumulus". However, when I send mail strange things happen. For most of the the western United States sending mail to "cumulus" works. Somewhere along the line a machine will substitute "d31jr0" for "cumulus" in the address. So, despite being sent to "cumulus" the mail is received as if it were sent to "d31jr0". Go east of the Mississippi and the mail bounces with the classic "host unknown". I believe the problem is with the sendmail.cf on d31jr0. Can anyone tell me how to get the sendmail to accept messages to "cumulus" and "d31jr0"? BTW d31jr0 is a dec 3100 running ultrix 3.1 Thanks Peter Kocks kocks@jessica.Stanford.EDU
