Normally, mail.local delivers mail to a file
owned by the recipient user in a central directory. That directory is

Beginning with V8.12 sendmail, you can tell
mail.local to instead deliver mail to a file in
each user's home directory. Simply use the
-h command-line switch to specify a filename that
will be common across all user's homes. For example:
Some pop3 servers move a users'
central mail to that user's home
mbox file before transferring it via
pop to the user. At such sites, when
pop3 is so configured, and when all users read
their mail with popd, there is an advantage to
delivering directly to each user's
mbox file with mail.local.
