13 .Sh DESCRIPTION
14 .Nm
15 is a mail filtering utility. It connects to remote mail servers using the
16 Internet Message Access Protocol (IMAP) and processes messages based on
17 the definition of filter rules. It can be used to delete, sort, etc.
18 messages residing in multiple mailboxes at different mail servers.
19 .Pp
20 The options are as follows:
21 .Bl -tag -width Ds
22 .It Fl c Ar configfile
23 Configuration file to read settings and filters from. The default is
24 .Pa $HOME/.imapfilterrc .
25 .It Fl d Ar interval
26 Runs imapfilter at daemon mode and repeatedly polls at the specified interval.
27 .It Fl h
28 Prints a summary of program's options.
29 .It Fl k
30 Kills any other running instances of
31 .Nm
32 and removes the lockfile left from a past session.
33 .It Fl l Ar logfile
34 File that contains logs of error messages
35 .Nm
36 produces and optionally information about the deleted messages.
37 .It Fl p
38 Enters the interactive encrypted passwords editor.
39 .It Fl q
40 Quiet mode; no informational messages at all printed.
41 .It Fl v
42 Verbose mode; prints detailed information about the program's actions.
43 .It Fl V
44 Displays program's version.
45 .El
46 .Pp
47 While running in daemon mode, if the SIGUSR1 signal is send,
48 .Nm
49 wakes up from its sleep phase and rereads its configuration file.
50 .Sh AUTHENTICATION AND ENCRYPTION
51 .Nm
52 supports the Challenge-Response Authentication Mechanism (CRAM) for
53 user authentication. The authentication type associated with CRAM is
54 CRAM-MD5.
55 .Nm
56 will authenticate using CRAM-MD5, if the mail server supports this
57 authentication method, instead of plaintext password LOGIN.
58 .Pp
59 .Nm
60 supports encryption of the connection with the IMAP STARTTLS extension,
61 and will try to negotiate a TLS connection if the mail server supports it.
62 .Pp
63 .Nm
64 supports imaps (port 993) SSL/TLS connections. The user must manually enable
65 imaps SSL/TLS connections and optionally specify the SSL/TLS protocol to be
66 negotiated, through
67 .Nm Ap s
68 configuration file.
69 .Sh PASSWORD EDITOR
70 .Nm
71 has the capability to encrypt the accounts' passwords and store them
72 separately at
73 .Pa $HOME/.imapfilter/passwords .
74 These passwords are encrypted with a master password, supplied by
75 the user. The Blowfish block cipher with a 128bit key in CBC mode
76 is used to do the encryption. The master password is entered each
77 time
78 .Nm
79 is run, in order to decrypt the password file and retrieve the
80 actual passwords of the user's IMAP mail accounts.
81 .Pp
82 First of all, while defining accounts in the
83 .Nm
84 configuration file, the user must specify only the username and server
85 in those accounts he/she wishes to encrypt the passwords before storage.
86 Then, one can enter the interactive passwords' editor by using the
87 .Fl p
88 option.
89 .Pp
90 After entering the interactive password editor, a command line prompt
91 is used to manage the passwords. The available commands are:
92 .Bl -tag -width Ds
93 .It Cm c
94 Clears a password from an account. It takes as an argument a
95 number, specifying which account's password should be cleared.
96 .It Cm e
97 Edits an account's password entry. It takes as an argument a
98 number, the account's password to be edited.
99 .It Cm h
100 Prints a brief help message of all commands.
101 .It Cm l
102 Lists all accounts. Specifically a number that describes the
103 account, the hostname of the IMAP mail server, the username
104 and the password (if one is already specified).
105 .It Cm p
106 Changes the master password, used to encrypt all other passwords.
107 .It Cm q
108 Quits the password editor without saving changes.
109 .It Cm w
110 Saves changes.
111 .It Cm x
112 Saves changes and exits the password editor.
