/usr/local/lib/mh/post [-alias aliasfile] [-filter filterfile] [-nofilter] [-format] [-noformat] [-mime] [-nomime] [-msgid] [-nomsgid] [-verbose] [-noverbose] [-watch] [-nowatch] [-width columns] file [-help]

DESCRIPTION
Post is the program called by send (1) to deliver the message in file to local and remote users. In fact, all of the functions attributed to send on its manual page are performed by post, with send acting as a relatively simple preprocessor. Thus, it is post which parses the various header fields, appends From: and Date: lines, and interacts with the SendMail transport system. Post will not normally be called directly by the user. Post searches the "To:", "cc:", "Bcc:", "Fcc:", 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. The `-width columns' switch can be used to indicate the preferred length of the header components that contain addresses. If a "Bcc:" field is encountered, its addresses will be used for delivery, and the "Bcc:" field will be removed from the message sent to sighted recipients. The blind recipients will receive an entirely new message with a minimal set of headers. Included in the body of the message will be a copy of the message sent to the sighted recipients. If `-filter filterfile' is specified, then this copy is filtered (re-formatted) prior to being sent to the blind recipients. Otherwise, to use the MIME rules for encapsulation, specify the `-mime' switch. The `-alias aliasfile' switch can be used to specify a file that post should take aliases from. More than one file can be specified, each being preceded with `-alias'. In any event, the primary alias file is read first. The `-msgid' switch indicates that a "Message-ID:" or "Resent-Message-ID:" field should be added to the header. The `-verbose' switch indicates that the user should be informed of each step of the posting/filing process. The `-watch' switch indicates that the user would like to watch the transport system's handling of the message (e.g., local and "fast" delivery). Post consults the envariable $SIGNATURE to determine the sender's personal name in constructing the "From:" line of the message.
