v LC_MESSAGES
v LC_TIME
v NLSPATH
See Appendix F for more information.
The ability of mail to handle doublebyte characters (or even 8-bit ASCII depends on
the underlying mail transport mechanism. You should restrict all messages to the
POSIX portable character set. To send messages containing doublebyte characters
or even binary files, encode them first with uuencode.
mail uses the following files:
dead.letter
The most recently canceled message.
mbox The default file for saving read mail, stored in the directory specified by
HOME.
0 The session was successfully completed; if reading, there was mail.
1 There was no mail, or the session could not be started.
2 An error occurred after starting the session, or you supplied an invalid
option, resulting in a usage message.
POSIX.2
Because this utility is due to be withdrawn from POSIX, you may want to use mailx
for portable applications. The ability to write directly to a file is an extension to
POSIX.
Any individual line is limited to LINE_MAX bytes; of course, transport mechanisms
between systems may impose shorter limits.
