Hi - I have a question that has been puzzling me for a while. My school's domain is set up like this: host.department.sjsu.edu. Now, in my local domain +ee.sjsu.edu, I do not have a machine called 'ee'. All mail now appears to have the header from: user@host.ee.sjsu.edu in this domain (all hosts are on the same net). Now, do I have to have a machine called ee to serve this domain if I want to send mail outside this domain and receive mail from outside this domain? How do I set up the sendmail.cf so that there appears to be a host called 'ee' but actually not while still allowing each host to have the fully qualified domainname host.ee.sjsu.edu appearing on the message header? One of the machines in this domain is serving as a mail host - say host1.ee.sjsu.edu. Do i have to name it 'ee' in order to get mail from outside? Thanks a lot for your help!

No, you don't. >How do I set up the >sendmail.cf so that there appears to be a host called 'ee' but actually not >while still allowing each host to have the fully qualified domainname >host.ee.sjsu.edu appearing on the message header? As I mentioned above, you don't need to do any of this, and it may be preferable not to, depending upon your site. If you want mail to be sent to ee.sjsu.edu, you could set this name up to have the same IP address as one of your hosts, in the domain tables. Then you could have a MX record for each host pointing to ee.sjsu.edu. Of course, you will have to be prepared to distribute the mail to the individual hosts from ee, i.e., nothing has been achieved by all this. One way could be to have a common /usr/mail or /usr/spool/mail mounted for all the hosts. The reverse makes more sense -- have all mail sent out with the sender as user@ee.sjsu.edu. And MX'es broadcast for ee.sjsu.edu pointing to your local hosts, with the common mail spool directory. If you wish to do this, Karl Kleinpaste (karl@cis.ohio-state.edu) has a nice generic cf file you can request. -- Govind N.
