post(8) 						      System Manager's Manual							   post(8)

NAME

       post - deliver a message

SYNOPSIS

       /usr/lib/mh/post [options] file

OPTIONS

       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 post also  con-
       sults  the file named in that entry.  Filters (re-formats) messages sent to blind copy recipients.  Recipients named in the Bcc: field nor-
       mally 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 compo-
       nents that contain addresses.

       The default settings for post are:

       -alias /usr/lib/mh/MailAliases -format -nomsgid -mts smtp -noverbose -nowatch -width 72 -nofilter

DESCRIPTION

       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 at-
       tributed 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 transport system.

       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.

RESTRICTIONS

       For this version, the -mts option only supports the value smtp. Additional values are supported for use only with other mail systems.

PROFILE COMPONENTS

       The post command does not consult the user's

FILES

       The system customization file.  The program to process Fcc:s.  The program to process Bcc:s.  The system alias file.
