post(8) System Manager's Manual post(8) NAME post - deliver a message SYNOPSIS /usr/lib/mh/post [ options ] file 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 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 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 flag 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 mes- sage. FLAGS -alias aliasfile Specifies a file that post should take aliases from. More than one file can be specified, each being preceded with the -alias option. post automatically consults the system alias file, /usr/lib/mh/MailAliases. If there is an Aliasfile en- try in your .mh_profile, post also consults the file named in that entry. -filter filterfile -nofilter 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. -format -noformat 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. -help Prints a list of the valid options to this command. -msgid -nomsgid Adds a Message-ID: or Resent-Message-ID: field to the header. -mts smtp 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. -verbose -noverbose Informs the user of each step of the posting/filing process. -watch -nowatch Allows the user to watch the transport system's handling of the message (for example, local and fast delivery). -width columns Specifies the preferred length of the header components that contain addresses. The default settings for post are: -alias /usr/lib/mh/MailAliases -format -nomsgid -mts smtp -noverbose -nowatch -width 72 -nofilter RESTRICTIONS For this version, the -mts option only supports the value smtp. Addi- tional values are supported for use only with other mail systems. PROFILE COMPONENTS The post command does not consult the user's .mh_profile. FILES /usr/lib/mh/mtstailor The system customization file. /usr/bin/mh/refile The program to process Fcc:s. /usr/lib/mh/mhl The program to process Bcc:s. /usr/lib/mh/MailAliases The system alias file.
