The mail spool is then NFS mounted by the clients. Playing with our newly installed mh 6.7, I discovered that if I do a inc on a machine which is NFS mounting the mail spool, then I can loose mail... in your mtstailor file, add the lockstyle option 1 to do the locking like SunOS expects: lockstyle: 1 and you shouldn't lose any mail, provided the machines have a consistent view of the spool file. (see below) If you are using standard unix mail, you have the risk of not seeing the mail (as the server and the client disagree for a while upgrade to SunOS 4.1 (now you can even get 4.1.1) which has an option to make the timeout instant just for this type of thing. this way, all machines have a consistent view of the spool files. hope this helps. v. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Vick Khera Gradual Student Department of Computer Science ARPA: khera@cs.duke.edu Duke University UUCP: ...!mcnc!duke!khera Durham, NC 27706 (919) 660-6528
