I've recently set up a Linux (slackware, kernel 2.0.26) machine as our
network's mail server/hub using sendmail. The /var/spool/mail directory
is exported and NFS mounted on other Linux machines, a SunOS4.1.1 machine
and two Solaris 2.5 machines.
The problem I have is when a user tries to READ mail on the Solaris machines.
Mail can be sent without problems but when an attempt is made to read the
mail, a .LOCK file is created with `----------' permission and `mail' hangs.
It also spits out the following:
WARNING: You are already reading mail.
This instance of mail is read only.
...which is damn strange since there is no other instance of mail running.
Can anyone give me a helping hand?
