NAME
inc - incorporate new mail to an nmh folder
SYNOPSIS
inc [-help] [-version] [+folder] [-audit audit-file] [-noaudit] [-changecur | -nochange-
cur] [-form formfile] [-format string] [-file name] [-silent | -nosilent] [-truncate
| -notruncate] [-width columns] [-host hostname] [-port portname/number] [-user user-
name] [-proxy command] [-sasl | -nosasl] [-saslmech mechanism] [-authservice service]
[-initialtls] [-notls] [-certverify | -nocertverify] [-snoop]
DESCRIPTION
inc incorporates mail from the user's incoming mail drop into an nmh folder. If the mail
drop is a file, it can be in mbox or MMDF format. If the mail drop is a directory it is
considered to be in Maildir format.
You may specify which folder to use with +folder. If no folder is specified, then inc
will use either the folder given by a (non-empty) "Inbox" entry in the user's profile, or
the folder named "inbox". If the specified (or default) folder doesn't exist, the user
will be queried prior to its creation.
When the new messages are incorporated into the folder, they are assigned numbers starting
with the next highest number for the folder. As the messages are processed, a scan list-
ing of the new mail is produced.
The newly created messages will have a mode of 0600, see chmod(1), on filesystems that
support it. Alternatively, a "Msg-Protect: nnn" profile entry gives the mode to use, in
octal. For all subsequent operations on these messages, this initially assigned mode will
be preserved.
If the switch -audit audit-file is specified (usually as a default switch in the user's
profile), then inc will append a header line and a line per message to the specified au-
dit-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 output audit information to this (or another) file, perhaps
with "Message-Id" information to keep an exact correspondence history. "Audit-file" is
assumed to be in the user's nmh directory unless a full path is specified.
inc will incorporate even improperly formatted messages into the user's nmh folder, in-
serting a blank line prior to the offending component and printing a comment identifying
the bad message.
In all cases, except the use of -file name (see below), the user's mail drop will be ze-
roed, 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 in the profile entry. 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 mail drop. Note that the named file will not be zeroed, unless the
-truncate switch is given.
The -file switch does not support the use of standard input. Instead, the rcvstore com-
mand can be used to incorporate mail from the standard input stream.
If the environment variable $MAILDROP is set, then inc uses it as the location of the
user's mail drop instead of the default (the -file name switch still overrides this, how-
ever). If this environment variable is not set, then inc will consult the profile entry
"MailDrop" for this information. If the value found is not absolute, then it is inter-
preted relative to the user's nmh directory. If the value is not found, then inc will
look in the standard system location for the user's mail drop.
The -silent switch directs inc to be quiet and not ask any questions at all. This is use-
ful for putting inc in the background and going on to other things.
Using POP
inc will normally check local mail drops for mail, as covered above. But if the option
"pophost" is set in "mts.conf", or if the -host hostname switch is given, or if the $MAIL-
HOST environment variable is set, then inc will query this POP service host for mail to
incorporate. If $MAILHOST is set and -host is specified as well, the command-line switch
will override the environment variable. The -port switch specifies the port name or num-
ber used to connect to the POP server. If unspecified, the default is "pop3".
To specify a username for authentication with the POP server, use the -user username
switch. The credentials profile entry in mh-profile(5) describes the ways to supply a
username and password.
If passed the -proxy command switch, inc will use the specified command to establish the
connection to the POP server. The string %h in the command will be substituted by the
hostname to connect to.
For debugging purposes, you may give the switch -snoop, which will allow you to monitor
the POP transaction. If -sasl -saslmech xoauth2 is used, the HTTP transaction is also
shown.
If nmh has been compiled with SASL support, the -sasl switch will enable the use of SASL
authentication. Depending on the SASL mechanism used, this may require an additional
password prompt from the user (but the netrc file can be used to store this password, as
described in mh-profile(5)). The -saslmech switch can be used to select a particular SASL
mechanism.
If SASL authentication is successful, inc will attempt to negotiate a security layer for
session encryption. Encrypted traffic is labelled with `(encrypted)' and `(decrypted)'
when viewing the POP transaction with the -snoop switch; see the post man page description
of -snoop for its other features.
If nmh has been compiled with OAuth support, the -sasl and -saslmech xoauth2 switches will
enable OAuth authentication. The -user switch must be used, and the user-name must be an
email address the user has for the service, which must be specified with the -authservice
service switch. Before using this, the user must authorize nmh by running mhlogin and
granting authorization to that account. See mhlogin(1) for more details.
If nmh has been compiled with TLS support, the -initialtls switch will require the negoti-
ation of TLS when connecting to the remote POP server. inc will negotiate TLS immediately
after the connection has taken place, before any POP commands are sent or received. Data
encrypted by TLS is labeled `(tls-encrypted)' and `(tls-decrypted)` when viewing the POP
transaction with the -snoop switch. The -notls switch will disable all attempts to nego-
tiate TLS.
When using TLS the default is to verify the remote certificate and SubjectName against the
local trusted certificate store. This can be controlled by the -certverify and -no-
certverify switches. See your OpenSSL documentation for more information on certificate
verification.
FILES
$HOME/.mh_profile The user's profile.
/etc/nmh/mts.conf mts configuration file.
/var/mail/$USER Location of the system mail drop.
PROFILE COMPONENTS
Path: To determine the user's nmh directory.
Alternate-Mailboxes:
To determine the user's mailboxes.
Inbox: To determine the 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.

DEFAULTS
+folder defaulted by "Inbox" above.
-noaudit
-changecur
-format As described above.
-nosilent
-nosasl
-notruncate Unless -file name is given.
-width The width of the terminal.
CONTEXT
The folder into which messages are being incorporated will become the current folder. 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.
