If the users are the same, it's easy. First, copy the mailboxes over
to the new machine (with tar/ftp, or NFS, etc...) into a temporary
directory, say /tmp/mail. Then do something like:
umask 077
cd /tmp/mail
for mailbox in *; do
if [ -e /var/mail/${mailbox}.lock ]
then echo "Mailbox for ${mailbox} busy, please do by hand"
else
touch /var/mail/${mailbox}.lock
cat ${mailbox} >> /var/mail/${mailbox}
chown ${mailbox} /var/mail/${mailbox} > /dev/null 2>&1
rm /var/mail/${mailbox}.lock
fi
done
There might be a race condition on very busy servers, but this should
be OK for most.
If for some reason an old user doesn't exist on the new machine, you
can "find /var/mail -type f -user root" and deal with them
accordingly.
If the usernames are different, then this is more difficult. :-)
