11 | .SH DESCRIPTION | |
12 | .B ezmlm-reject | |
13 | reads a mail message from its standard input. | |
14 | It rejects the message if it sees something it doesn't like. | |
f8beb284 MW |
15 | |
16 | If the message has a ``Precedence: junk'' header, | |
17 | .B ezmlm-reject | |
18 | exits 99 causing the message to be ignored. This causes replies from (some) | |
19 | vacation programs to be ignored. | |
20 | ||
21 | If | |
22 | .I dir | |
23 | is specified, | |
24 | .B ezmlm-reject | |
25 | reads | |
26 | .I dir\fB/msgsize | |
27 | for a maximum:minimum message body size in bytes. Either number will be ignored | |
28 | if 0 or omitted. | |
29 | .B ezmlm-reject | |
30 | will also look for | |
31 | .I dir\fB/mimereject | |
32 | and | |
33 | .IR dir\fB/mimeremove . | |
34 | if | |
35 | .IR dir\fB/mimereject | |
36 | exists, | |
37 | Messages of the Content-Types specified or with MIME parts of these | |
38 | types will be rejected. | |
39 | If | |
40 | .I dir\fB/mimeremove | |
41 | exists, | |
42 | .B ezmlm-reject | |
43 | will reject messages of the Content-Types specified. These content-types will | |
44 | be accepted as parts of a composite MIME message. They will be | |
45 | stripped out later by | |
46 | .BR ezmlm-send(1) . | |
47 | ||
48 | .B ezmlm-reject | |
49 | will exit 100 (permanent error) for rejections. If the list address is not in | |
50 | the message ``To:'' or ``Cc:'' headers and the | |
51 | .B \-t | |
52 | switch is active, the exit code is 100 or 99, depending on the | |
53 | .B \-q | |
54 | switch (see below). | |
55 | If you would like to forward messages instead of rejecting them, you can | |
56 | into the appropriate .qmail file put: | |
57 | ||
58 | .EX | |
59 | |condredirect newaddress except /path/ezmlm-reject DIR | |
60 | .EE | |
61 | ||
62 | Now rejected posts will | |
63 | go to this address, and the recipient can take appropriate action. | |

67 | Reject the message if the message body starts ``subscribe'' | |
68 | or ``unsubscribe''. If the | |
69 | .B \-c | |
70 | switch is specified, messages will also be rejected if the subject starts | |
71 | with these words. | |
72 | .B \-B | |
73 | (Default.) | |
74 | Do not reject messages starting ``subscribe'' or ``unsubscribe''. | |

85 | .B \-h |
86 | Reject message if any of the headers in | |
87 | .I dir\fB/headerreject | |
88 | occur in the header. Mailing-List headers of other mailing list managers | |
89 | can be put into this file, one per line, to prevent processing of messages | |
90 | from other mailing lists. | |
91 | .I dir | |
92 | must be specified. | |
93 | ||
94 | A reasonable set of headers would be: ``Mailing-List'', ``X-ml-name'', | |
95 | \``ml-name'',``X-loop'',``X-listprocessor-version'',``X-mailing-list''. Case | |
96 | is not important. | |
97 | .TP | |
98 | .B \-H | |
99 | (Default.) | |
100 | Ignore | |
101 | .IR dir\fB/headerreject . | |
102 | .B \-q | |
103 | Quiet. If the message due to the lack of the list address (see | |
104 | .BR \-t ) | |
105 | is not accepted, this is logged but no error message is sent to the sender. | |
106 | .TP | |
107 | .B \-q | |
108 | Quiet. If a message due to the lack of the list address (see | |
109 | .BR \-t ) | |
110 | is not accepted, | |
111 | the message is silently ignored. | |
112 | .TP | |
113 | .B \-Q | |
114 | (Default.) | |
115 | Not quiet. If a message due to the lack of the list address (see | |
116 | .BR \-t ) | |
117 | is not accepted, | |
118 | the sender is notified by an error message. | |

127 | .B \-t | |
128 | (Default.) | |
129 | Reject messages that do not have the list address in the ``To:'' or ``Cc:'' | |
130 | header(s). | |
131 | .B ezmlm-reject | |
132 | needs access to | |
133 | .I dir\fB/outhost | |
134 | and | |
135 | .I dir\fB/outlocal | |
136 | to check this. This check is silently omitted if | |
137 | .I dir | |
138 | is not specified, to assure backwards compatibility with existing ezmlm lists. | |
139 | .TP | |
140 | .B \-T | |
141 | Do not require the list address in the ``To:'' or ``Cc:'' header(s). | |
142 | .SH BUGS | |
143 | .B ezmlm-reject | |
144 | does not handle rfc822 comments in ``Content-Type:'' lines if present | |
145 | before the type or boundary. | |
146 | This could be used to defeat the | |
147 | MIME rejection function. | |
148 | OTOH, this function is intended to reduce garbage, not guarantee | |
149 | its elimination. | |
