It uses mbox format, with lockf locking on systems +that don't have flock (HP/UX, Solaris), and flock locking otherwise. + +This file explains how to switch your system to ~user/Mailbox. You +aren't required to do this; for further discussion of /var/spool/mail, +and an explanation of how to continue using binmail for local +deliveries, see INSTALL.vsm. + +The basic procedure for switching to ~user/Mailbox is simple: + + * Move each /var/spool/mail/user to ~user/Mailbox. For safety, do + this in single-user mode. + + * As root, set up a symbolic link from /var/spool/mail/user to + ~user/Mailbox for each user. /var/spool/mail should be mode 1777, + so users will not be able to accidentally remove these links. + +A few mail programs are unable to handle symbolic links, so you will +have to configure them to look at ~user/Mailbox directly: + + * procmail: Change SYSTEM_MBOX in config.h and recompile; or, with + recent versions, define MAILSPOOLHOME in src/authenticate.c. + +An alternative to symbolic links is hlfsd. Consult the documentation for +hlfsd if it is included in your operating system. + +If /var/spool/mail is large, you can gain extra speed by configuring +all your mail software to look at ~user/Mailbox directly: + + * Most MUAs: Put ``setenv MAIL $HOME/Mailbox'' in your system-wide + .cshrc and ``MAIL=$HOME/Mailbox; export MAIL'' in your system-wide + .profile. + + * elm: Change "mailbox" to "Mailbox" around line 388 of newmbox.c and + recompile. (elm looks at $MAIL, but without this change elm will + fail if two users try to read mail simultaneously.) + + * pine: Put ``inbox-path=Mailbox'' in your system-wide pine.conf. + (For pine versions more recent than 3.91, see also FAQ 6.2.) + + * qpopper 2.2: Change /.mail to /Mailbox in pop_dropcopy.c and + recompile with -DHOMEDIRMAIL in CFLAGS. + +Some vendors, in a misguided attempt to solve the security problems of +/var/spool/mail, have made all their mail software setgid mail. After +you move the mailboxes, you can---and, for security, should---remove +those setgid-mail bits. -- cgit v1.2.3
