INC(1)

NAME
inc - incorporate new mail

SYNOPSIS
inc [+folder] [-audit audit-file] [-noaudit] [-changecur] [-nochangecur] [-form formatfile] [-format string] [-file name] [-silent] [-nosilent] [-truncate] [-notruncate] [-width columns] [-host host] [-user user] [-apop] [-noapop] [-rpop] [-norpop] [-pack file] [-nopack] [-help]

DESCRIPTION
Inc incorporates mail from the user's incoming mail drop into an MH folder. If `+folder' isn't specified, a folder in the user's MH directory will be used, either that specified by the “Inbox:” entry in the user's profile, or the folder named “inbox”. The new messages being incorporated are assigned numbers starting with the next highest number in the folder. If the specified (or default) folder doesn't exist, the user will be queried prior to its creation. As the messages are processed, a scan listing of the new mail is produced. If the user's profile contains a “Msg-Protect: nnn” entry, it will be used as the protection on the newly created messages, otherwise the MH default of 0644 will be used. During all operations on messages, this initially assigned protection will be preserved for each message, so chmod(1) may be used to set a protection on an individual message, and its protection will be preserved thereafter. If the switch `-audit audit-file' is specified (usually as a default switch in the profile), then inc will append a header line and a line per message to the end of the specified audit-file with the format:
inc date
<scan line for first message>
<scan line for second message>
<etc.>
This is useful for keeping track of volume and source of incoming mail. Eventually, repl, forw, comp, and dist may also produce audits to this (or another) file, perhaps with “Message-Id:” information to keep an exact correspondence history. “Audit-file” will be in the user's MH directory unless a full path is specified. Inc will incorporate even improperly formatted messages into the user's MH folder, inserting a blank line prior to the offending component and printing a comment identifying the bad message. In all cases, the user's mail drop will be zeroed, unless the `-notruncate' switch is given. If the profile entry “Unseen-Sequence” is present and non-empty, then inc will add each of the newly incorporated messages to each sequence named by the profile entry. This is similar to the “Previous-Sequence” profile entry supported by all MH commands which take `msgs' or `msg' arguments. Note that inc will not zero each sequence prior to adding messages. The interpretation of the `-form formatfile', `-format string', and `-width columns' switches is the same as in scan (1). By using the `-file name' switch, one can direct inc to incorporate messages from a file other than the user's maildrop. Note that the name file will NOT be zeroed, unless the `-truncate' switch is given. If the envariable $MAILDROP is set, then inc uses it as the location of the user's maildrop instead of the default (the `-file name' switch still overrides this, however). If this envariable is not set, then inc will consult the profile entry “MailDrop” for this information. If the value found is not absolute, then it is interpreted relative to the user's MH directory. If the value is not found, then inc will look in the standard system location for the user's maildrop. The `-silent' switch directs inc to be quiet and not ask any questions at all. This is useful for putting inc in the background and going on to other things. If the local host is configured as a POP client, or if the `-host host' switch is given, then inc will query the POP service host as to the status of mail waiting. If the `-user user' switch is not given, then the current username is used. Normally, inc will prompt for a password to use. However, if the `-apop' switch is given, inc will generate authentication credentials to provide for origin authentication and replay protection, but which do not involve sending a password in the clear over the network. Otherwise, if the `-rpop' switch is given, then inc will try to use a “trusted” connection (ala the BSD r-commands). If inc uses POP, then the `-pack file' switch is considered. If given, then inc simply uses the POP to packf (1) the user's maildrop from the POP service host to the named file. This switch is provided for those users who prefer to use msh to read their maildrops. ^$HOME/.mh_profile~^The user profile ^/usr/pkg/libexec/mh/mtstailor~^tailor file ^/var/mail/$USER~^Location of mail drop ^Path:~^To determine the user's MH directory ^Alternate-Mailboxes:~^To determine the user's mailboxes ^Inbox:~^To determine the inbox, default “inbox” ^Folder-Protect:~^To set mode when creating a new folder ^Msg-Protect:~^To set mode when creating a new message and audit-file ^Unseen-Sequence:~^To name sequences denoting unseen messages Post Office Protocol - version 3 (aka RFC-1081),

The first message incorporated will become the current message, unless the `-nochangecur' option is specified. This leaves the context ready for a show of the first new message. The argument to the `-format' switch must be interpreted as a single token by the shell that invokes inc. Therefore, one must usually place the argument to this switch inside double-quotes.
