mhmail - send or read mail
mhmail [addrs ...] [-body text] [-cc addrs [-from addr] [-subject
subject] [-version] [-help]
mhmail is intended as a replacement for the standard Berkeley mail
program (mail or mailx), which is compatible with nmh. This program is
intended for the use of programs such as cron, which expect to send
mail automatically to various users. It is also used by various nmh
commands to mail various error notifications. Although mhmail can be
used interactively, it is recommended that comp and send be used
instead to send messages.
When invoked without arguments, it simply invokes inc to incorporate
new messages from the user’s maildrop. When one or more users is
specified, a message is read from the standard input and spooled to a
temporary file. mhmail then invokes post with the name of the
temporary file as its argument to deliver the message to the specified

force an empty message.
Normally, addresses appearing as arguments are put in the “To:” field.
If the -cc switch is used, all addresses following it are placed in the
By using -from addr, you can specify the “From:” header of the draft.
Naturally, post will fill-in the “Sender:” header correctly.
