in the behavior via the previously default #define DONT_FSYNC, use the -s flag to turn the fsync() behavior on. This can be configured in sendmail.cf without recompiling mail.local.

|
|
.Ar user ...
|
|
.Sh DESCRIPTION
|
|
.Nm Mail.local
|
|
reads the standard input up to an end-of-file and appends it to each
|
|
.Ar user's
|
|
.Pa mail
|
|
file.
|
|
The
|
|
.Ar user
|
|
must be a valid user name.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width xxxfrom
|
|
.It Fl f Ar from
|
|
Specify the sender's name.
|
|
.It Fl b
|
|
Turn off the attempts to notify the
|
|
.Dq biff
|
|
service.
|
|
.It Fl s
|
|
Turn on the
|
|
.Xr fsync 2
|
|
call that forces the mailbox to be committed to disk before returning a
|
|
.Dq success
|
|
status. (This can configured in the flags passed through from
|
|
.Xr sendmail 8 ).
|
|
.El
|
|
.Pp
|
|
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).
|
|
.Pp
|
|
The mail files are exclusively locked with
|
|
.Xr flock 2
|
|
while mail is appended,
|
|
and a
|
|
.Pa user.lock
|
|
file also is created while the mailbox is locked
|
|
for compatibility with older MUAs.
|
|
.Pp
|
|
If the ``biff'' service is returned by
|
|
.Xr getservbyname 3 ,
|
|
the biff server is notified of delivered mail.
|
|
.Pp
|
|
The
|
|
.Nm mail.local
|
|
utility exits 0 on success, and >0 if an error occurs.
|
|
.Sh ENVIRONMENT
