post - deliver a message
/usr/lib/mh/post [options] file
Specifies a file that post should take aliases from. More than one file
can be specified, each being preceded with the -alias option. The post
program automatically consults the system alias file,
/usr/lib/mh/MailAliases. If there is an Aliasfile entry in your
.mh_profile, post also consults the file named in that entry.
Filters (re-formats) messages sent to blind copy recipients.
Recipients named in the Bcc: field normally receive a new message which
includes a copy of the message sent to the other recipients. If this
option is specified, this copy of the message is filtered according to
the instructions in the named file. The default is -nofilter.
Formats messages so as to conform to ARPAnet Internet Message Format
protocol. This is the default behavior. You can post from formatting
messages in this way by using the -noformat option.
Prints a list of the valid options to this command.
Adds a Message-ID: or Resent-Message-ID: field to the header.
Specifies the mail system over which mail is sent. The only value
allowed is smtp, which is the standard mail system. Additional values
are supported only for use with other mail systems.
Informs the user of each step of the posting/filing process.
Allows the user to watch the transport system's handling of the message
(for example, local and fast delivery).
Specifies the preferred length of the header components that contain
The default settings for post are:
The program post is called by send(1) to deliver the message in the named
file to local and remote users. In fact, all of the functions attributed to
send on its reference page are performed by post, with send acting as a
relatively simple pre-processor. Thus, it is post which parses the various
header fields, appends From: and Date: lines, and interacts with the
Normally, post would not be called directly by the user.
It searches the To:, cc:, Bcc:, and Resent-xxx: header lines of the
specified message for destination addresses, checks these addresses for
validity, and formats them so as to conform to ARPAnet Internet Message
Format protocol (unless the -noformat option is set). This will normally
cause @local-site to be appended to each local destination address, as well
as any local return addresses.
If a Bcc: field is encountered, the mail system will use its addresses for
delivery. The Bcc: is removed from the message sent to original recipients.
The copied recipients will receive an entirely new message with a minimal
set of headers. The mail system includes a copy of the message sent to the
original recipients in the body of the message.
This command consults the environment variable $SIGNATURE to determine the
sender's personal name in constructing the From: line of the message.
For this version, the -mts option only supports the value smtp. Additional
values are supported for use only with other mail systems.
The post command does not consult the user's .mh_profile.
