/var/qmail/queue
/var/qmail/queue is the one thing you simply CANNOT share; qmail cannot
queue messages through NFS. (Read INSTALL.maildir; you'll see that Dan
takes a dim view of NFS.)
/var/qmail/control
Sharing /var/qmail/control is possible, if you're careful. It probably
means that home directories are NFS mounted, and passwords are NIS
shared. This in turn means:
1. mbox delivery is deprecated; use Maildir. See INSTALL.maildir,
INSTALL.mbox and INSTALL.vsm.
2. Mail will bounce unless you follow the steps in FAQ 4.9: "How do
I make qmail defer messages during NFS or NIS outages?"
An alternative to sharing is to use sed and rsync (with "-e ssh").
The qmail Makefile contains an elegant use of sed for that purpose.
/var/qmail/bin
You certainly can share /var/qmail/bin if you want. Make sure the
qmail users and groups have the same IDs on every host. Also, paths
need to agree: for example /var/qmail/queue should always get you to
the right place.
/var/qmail/alias
Can be shared. Remember, it's a home directory; use Maildir. Also,
it's your problem to make sure that .qmail-* files work everywhere.
HTH,
Len.
