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
|
|
flock(2)
|
|
while mail is appended,
|
|
and a
|
|
.B user.lock
|
|
file also is created while the mailbox is locked
|
|
for compatibility with older MUAs.
|
|
.PP
|
|
If the ``biff'' service is returned by
|
|
getservbyname(3),
|
|
the biff server is notified of delivered mail.
|
|
.PP
|
|
The
