is a mail filtering utility. It connects to remote mail servers using the |

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. |

.Sh AUTHENTICATION AND ENCRYPTION |
47 |
|
|
.Nm |
48 |
|
|
supports the Challenge-Response Authentication Mechanism (CRAM) for |
49 |
|
|
user authentication. The authentication type associated with CRAM is |
50 |
|
|
CRAM-MD5. |
51 |
|
|
.Nm |
52 |
|
|
will authenticate using CRAM-MD5, if the mail server supports this |
53 |
|
|
authentication method, instead of plaintext password LOGIN. |
54 |
|
|
.Pp |
55 |
|
|
.Nm |
56 |
|
|
supports encryption of the connection with the IMAP STARTTLS extension, |
57 |
|
|
and will try to negotiate a TLS connection if the mail server supports it. |
58 |
|
|
.Pp |
59 |
|
|
.Nm |
60 |
|
|
supports imaps (port 993) SSL/TLS connections. The user must manually enable |
61 |
|
|
imaps SSL/TLS connections and optionally specify the SSL/TLS protocol to be |
62 |
|
|
negotiated, through |
63 |
|
|
.Nm Ap s |
64 |
|
|
configuration file. |

.Sh PASSWORD EDITOR |
66 |
|
|
.Nm |
67 |
|
|
has the capability to encrypt the accounts' passwords and store them |
68 |
|
|
separately at |
69 |
|
|
.Pa $HOME/.imapfilter/passwords . |
70 |
|
|
These passwords are encrypted with a master password, supplied by |
71 |
|
|
the user. The Blowfish block cipher with a 128bit key in CBC mode |
72 |
|
|
is used to do the encryption. The master password is entered each |
73 |
|
|
time |
74 |
|
|
.Nm |
75 |
|
|
is run, in order to decrypt the password file and retrieve the |
76 |
|
|
actual passwords of the user's IMAP mail accounts. |
77 |
|
|
.Pp |
78 |
|
|
First of all, while defining accounts in the |
79 |
|
|
.Nm |
80 |
|
|
configuration file, the user must specify only the username and server |
81 |
|
|
in those accounts he/she wishes to encrypt the passwords before storage. |
82 |
|
|
Then, one can enter the interactive passwords' editor by using the |
83 |
|
|
.Fl p |
84 |
|
|
option. |
85 |
|
|
.Pp |
86 |
|
|
After entering the interactive password editor, a command line prompt |
87 |
|
|
is used to manage the passwords. The available commands are: |
88 |
|
|
.Bl -tag -width Ds |
89 |
|
|
.It Cm c |
90 |
|
|
Clears a password from an account. It takes as an argument a |
91 |
|
|
number, specifying which account's password should be cleared. |
92 |
|
|
.It Cm e |
93 |
|
|
Edits an account's password entry. It takes as an argument a |
94 |
|
|
number, the account's password to be edited. |
95 |
|
|
.It Cm h |
96 |
|
|
Prints a brief help message of all commands. |
97 |
|
|
.It Cm l |
98 |
|
|
Lists all accounts. Specifically a number that describes the |
99 |
|
|
account, the hostname of the IMAP mail server, the username |
100 |
|
|
and the password (if one is already specified). |
101 |
|
|
.It Cm p |
102 |
|
|
Changes the master password, used to encrypt all other passwords. |
103 |
|
|
.It Cm q |
104 |
