Hi all. I was hoping that someone could help with a rather obscure techinique I'm trying to implement with sendmail.
Basically our network has two different mail servers - one for a student network, and one for administration staff. They both accept mail for the same domain address. Now all the mail from outside is first delievered to the admin server (it is also the network gateway), then any mail that is explicitly known to be for a student is passwd on to the student mail server (via entries in the aliases file - such as "student: [EMAIL PROTECTED]"). However, when a student sends outgoing mail, it is sent first to the student mail server. If the mail is for a local address the student server must then determine if it is actually for an admin account, and if so pass it on to the admin server (again this is currently done by entries in the aliases file - such as "adminuser: [EMAIL PROTECTED]"). Confusing? Now what I am trying to do is remove the need for each machine to know exactly what users are on the other. I have done this for incoming mail by configuring the admin server to forward any mail for unknown users to the student server so that it can attempt delivery. I tried to do the same for the student server, but the problem is that any mail for a real unknown address ends up boncing back and forth between the two servers. What I would like to do is to configure sendmail to first check if the mail has allready been through the other machine before relaying unknown users to it - but as you've probably guessed I really wouldn't know where to begin. Any help would be greatly appreciated. Chris -- E-mail the word "unsubscribe" to [EMAIL PROTECTED] TO UNSUBSCRIBE FROM THIS MAILING LIST. Trouble? E-mail to [EMAIL PROTECTED] .
