This is the command mhmailmh that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
mhmail - send or read mail
mhmail [-to] addrs ... [-attach file] [-body text] [-cc addrs ...] [-from addr]
[-headerfield name:value] [-subject subject] [-resent] [switches for post ... |
-profile [switches for send ...]] [-send | -nosend] [-version] [-help]
mhmail with no arguments is equivalent to inc
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 addresses. 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
When one or more addresses are specified, a message is read from the standard input and
spooled to a temporary file. mhmail then invokes post, by default, with the name of the
temporary file as its argument to deliver the message to the specified address.
The -subject subject switch can be used to specify the “Subject:” field of the message.
The -resent switch indicates that the message body is a fully formed message that will be
resent, as dist would do. For example:
mhmail firstname.lastname@example.org -resent < `mhpath cur`
By default, mhmail will read the message to be sent from the standard input. You can
specify the text of the message at the command line with the -body text switch. If the
standard input has zero length, mhmail will not send the message and return with status 1.
You can use the switch -body “” to force an empty message.
Normally, addresses appearing as arguments are put in the “To:” field. At least one such
address is required when sending a message, i.e., if any other switches are supplied. If
the -cc switch is used, all addresses following it, even if there are intervening switches
other than -to, are placed in the “cc:” field. The optional -to switch can appear in
front of any addresses to signify their placement in the “To:” field. The -to and -cc
switches may be given multiple times.
By using -from addr, you can specify the “From:” header of the draft. If no -from switch
is used when sending, mhmail will supply a “From:” header field using the sender's local
mailbox, see localmbox in mh-format(5). Naturally, post will fill-in the “Sender:” header
The -headerfield name:value switch adds a header field with the specified name and value
to the message. (The value is called the field body in RFC 2822, but that's too easily
confused with the message body.) There need not be a space after the colon that separates
the name and value in the argument to this switch. It is usually best to enclose the
argument in quotes to protect it from the shell. The -headerfield switch may be given
multiple times to add multiple header fields, for example,
mhmail -from email@example.com \
-headerfield 'MIME-Version:1.0' \
-headerfield 'Content-Type:text/plain; charset=utf-8' \
-headerfield 'Content-Transfer-Encoding:8bit' \
Note about this example: the -attach switch causes MIME-Version and Content-Type headers
to be added to the message.
The -profile switch instructs mhmail to use send instead of post to send the message.
This allows use of the user's context and aliases.
The -attach file switch attaches the specified file to the message. Use of -attach
enables -profile because mhmail uses send to handle the attachment. It is usually best to
enclose the argument in quotes to protect it from the shell. The -attach switch may be
given multiple times to add multiple attachments.
The -nosend option shows the draft file that would be posted/sent on the command's
standard output but does not post or send it. -send provides the default behavior of
posting or sending the message. It can be used to disable -nosend, for example, when
using a shell alias.
All other switches are passed on to post if -profile is not used, or send if -profile is
