mail.local - store mail in a mailbox

Mail.local  reads  the  standard input up to an end-of-file and appends it to each user'smail file.  The
       user must be a valid user name.

       The options are as follows:

       -7        Do not advertise 8BITMIME support in LMTP mode.

       -b        Return a permanent error instead of a temporary error if a mailbox exceeds quota.

       -d        Specify this is a delivery (for backward compatibility).  This option has no effect.

       -Dmbdb   Specify the name of the mailbox database which is used to look up local recipient names.   This
                 option defaults to "pw", which means use getpwnam().

       -ffrom   Specify the sender's name.

       -l        Turn on LMTP mode.

       -rfrom   Specify the sender's name (for backward compatibility).  Same as -f.

       -hfilename
                 Store  incoming  mail  in  filename in the user's home directory instead of a system mail spool
                 directory.

       The next options are only available if mail.local has been compiled with -DHASHSPOOL.

       -Hhashtypehashdepth
              Select hashed mail directories.  Valid hash types are u for user name  and  m  for  MD5  (requires
              compilation  with  -DHASHSPOOLMD5).  Example: -Hu2 selects user name hashing with a hash depth of
              2.  Note: there must be no space between the hash type and the depth.

       -ppath
              Specify an alternate mail spool path.

       -n     Specify that the domain part of recipient addresses in LMTP mode should not be stripped.

       Individual mail messages in the mailbox are delimited by an empty line followed by a line beginning  with
       the  string  ``From  ''.   A  line containing the string ``From '', the sender's name and a time stamp is
       prepended to each delivered mail message.  A blank line is appended  to  each  message.   A  greater-than
       character  (``>'')  is  prepended  to  any  line  in  the message which could be mistaken for a ``From ''
       delimiter line (that is, a line beginning with the five characters ``From '' following a blank line).

       The mail files are exclusively locked with flock(2) while mail is appended, and a user.lock file also  is
       created while the mailbox is locked for compatibility with older MUAs.

       If the ``biff'' service is returned by getservbyname(3), the biff server is notified of delivered mail.

       The mail.local utility exits 0 on success, and >0 if an error occurs.

       TZ     Used to set the appropriate time zone on the timestamp.

       /tmp/local.XXXXXX     temporary files
       /var/mail/user        user's default mailbox directory
       /var/mail/user.lock   lock file for a user's default mailbox

       A superset of mail.local (handling mailbox reading as well as mail delivery) appeared in Version  7  AT&T
       UNIX as the program mail.

mail.local  escapes  only  "^From  " lines that follow an empty line.  If all lines starting with "From "
       should be escaped, use the 'E' flag for the local mailer in the sendmail.cf file.
