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
Turn off the attempts to notify the
``biff''
service.
-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.
-D mbdb
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().
-f from
Specify the sender's name.
-l
Turn on LMTP mode.
-s
Turn off the
fsync(2)
call that forces the mailbox to be committed to disk before returning a
``success''
status.
-r from
Specify the sender's name (for backward compatibility).
Same as -f.
-h filename
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.
-H hashtypehashdepth
Select hashed mail directories.
Valid hash types are
u
for user name and
m
for MD5 (requires compilation with -DHASHSPOOLMD5).
Example:
-H u2
selects user name hashing with a hash depth of 2.
Note: there must be no space between the hash type and the depth.
-p path
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.
ENVIRONMENT
TZ
Used to set the appropriate time zone on the timestamp.
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.
HISTORY
A superset of
mail.local
(handling mailbox reading as well as mail delivery)
appeared in
Version 7 AT&T UNIX
as the program
