HP-UX Reference (11i v2 07/12) - 1 User Commands A-M (vol 1)

m
mail(1) mail(1)
mail treats a line consisting solely of a dot (
. ) as the end of the message, except when the rmail -d
command is used.
The maximum allowable line length in mail messages is 8 times that of
BUFSIZ bytes as defined in
/usr/include/stdio.h
. If line length exceeds this limit,
mail truncates the line starting at
beginning-of-line, and uses only the trailing 8 *
BUFSIZ characters.
Using two separate mail programs to access the same mail file simultaneously (usually inadvertently from
two separate windows) can cause unpredictable results.
Some sites that have programs that adhere strictly to RFC-822 will fail to deliver a message if any of the
recipient fields below is missing.
