<!-- <li>2004/08/23 - v4.2.1+cvs (<a href="files/sa-exim-cvs.tar.gz">sa-exim cvs tar.gz</a>
2
    (latest version available via CVS only, or a somewhat recent via
3
    <a href="files/sa-exim-cvs.tar.gz">this link</a>) -->
4
 
5
<li>2006/01/09 - v4.2.1 (<a href="files/sa-exim-4.2.1.tar.gz">sa-exim.tar.gz</a>
6
or <a href="files/local_scan/local_scan.c_4.2.1">local_scan only</a>)
7
    <br><b>Security update</b> (reported by Chris Morris)
8
    <ul>
9
    <li>Modified Greylisting.pm not to generate tuplets with spaces, although
10
        the cleaning cron job is now safe with regard to whitespace
11
    <li>Included Mark Lawrence's perl script to better clean old tuplets
12
    <li>The default config now ships with the greylistclean cronjob running
13
        as nobody (which spamd should be running as, too)
14
    </ul>
15
 
16
<li>2005/01/17 - v4.2 (<a href="files/sa-exim-4.2.tar.gz">sa-exim.tar.gz</a>
17
or <a href="files/local_scan/local_scan.c_4.2">local_scan only</a>)
18
    <br><b>Do not use, greylistclean is insecure, use 4.2.1 instead</b>
19
    <ul>
20
    <li>Fixed code so that it compiles inside the exim tree too (thanks Jason)
21
    <li>Support SA 3.0 new score reporting format (score= instead of hits=)
22
    <li>Proper SA 3.0 plugin support
23
    <li>Documentation updates
24
    <li>greylisting files now also save the last SA score, just in case
25
    <li>Saved files are now group read/write too, if you need to shut off group
26
        access, do it at the directory level
27
    <li>Only rewrite Content-Type/Content-Transfer-Encoding if SARewriteBody is
28
        on now (this used to be useful with old SA versions and defang_mime
29
        but those options are gone). Suggested by Adam Tilghman.
30
    <li>Finally made all score threshold variables exim conditions that are
31
        evaluated at runtime
32
    <li>SAteergrubecond is deprecated as a result
33
    </ul>
34
 
35
<li>2004/08/16 - v4.1 (<a href="files/sa-exim-4.1.tar.gz">sa-exim.tar.gz</a>
36
or <a href="files/local_scan/local_scan.c_4.1">local_scan only</a>)
37
    <b>Please see the mailing list, or use the CVS version if you are compiling
38
    sa-exim inside your exim tree</b> (there is a small mistake in the source
39
    which will prevent proper building) / <b>You also need CVS if you are
40
    using SA 3.0</b>
41
    <ul>
42
    <li>Deal with being called with the number of recipients is 0 (reported by
43
        John Horne)
44
    <li>Made hopefully fully 64 bit clean (well, it was written that way,
45
        except for that pesky printf in C, which got in the way). Kudos go to
46
        Adam D. Barratt for finding and explaining the bug
47
    <li>Switched to using strchr instead of index to remove compilation warnings
48
        on some systems (reported by John Horne/Jeff Carter)
49
    <li>Added SAspamcHost/SAspamcPort at the request of several people
50
    <li>Fixed mbox From file to be standards complaint (reported by Cliff Hones)
51
    <li>Added SAFEMESGIDCHARS option for safer message-id based filenames
52
    <li>New version of the SA patch, with safe file creation (clean env from
53
        and rcpt to before using as directory names)
54
    <li><b>IMPORTANT</b>: if you are using greylisting, and applied the
55
        previous greylisting patch, it didn't create shell safe filenames,
56
        it is therefore highly recommended that you apply the new version
57
    <li>Added a quick patch to sa-exim to deal with headers that are longer
58
        than 8K (and drop the remaining lines)
59
    </ul>
60
 
61
 
62
<li>2004/03/16 - v4.0 (<a href="files/sa-exim-4.0.tar.gz">sa-exim.tar.gz</a>
63
or <a href="files/local_scan/local_scan.c_4.0">local_scan only</a>)
64
    <ul>
65
    <li>Added SAspamcpath (from Richard Lithvall)
66
    <li>Makefile fixes for version.h and dependencies
67
    <li>Added exim acl_m trick from Chirik in README
68
    <li>New code to read and pass on any X-Spam- header from SpamAssassin
69
    <li>Message-Id is now logged in SA log entries to allow you track down
70
        a message in other logfiles, like SA's log
71
    <li>Add X-SA-Exim-Connect-IP header for greylisting
72
    <li>Allow for tempreject on messages not flagged as spam by SA (for
73
        greylisting)
74
    <li>Added greylisting support (see README.greylisting)
75
    <li>Added the following options to sa-exim.conf:
76
        <ul>
77
        <li>SAspamcSockPath
78
        <li>SAgreylistiswhitestr
79
        <li>SAgreylistraisetempreject
80
        </ul>
81
    <li>Lots of documentation fixes and updates
82
    <li>Basic debian tree shipped by default (but real deb package from Sander
83
        Smeenk)
84
    </ul>
85
 
86
<li>2003/08/18 - v3.1 (<a href="files/sa-exim-3.1.tar.gz">sa-exim tar.gz</a>
87
    or <a href="files/local_scan/local_scan.c_3.1">local_scan only</a>)
88
    <ul>
89
    <li>Fixed <em>SA: Action: teergrubed sender until full configured duration</em> output
90
    <li>spamassassin.conf was renamed sa-exim.conf (bad initial name choice)
91
    <li>Changed teergrubing so that it works with exim 4.20 and above
92
    <li>Added the much requested SARewriteBody option for SA 2.50's report_safe
93
        (courtesy of Richard Lithvall)
94
    <li>Added SAaddSAEheaderBeforeSA to deal with SARewriteBody and privacy
95
    <li>Added SAPrependArchiveWithFrom option (Richard Lithvall)
96
    <li>As announced in the previous version, SAStallSender was removed.
97
        Use Teergrubing instead
98
    <li>Message-Id is read directly from Exim now that the API allows for that
99
        (we used to parse the Message-Id header ourselves) -&gt; except that
100
        we don't use this for logging or saving messages: as soon as we can
101
        read the real Message-Id from the headers, we use that Message-Id for
102
        logging (this is to facilitate tracking of messages from the logs and
103
        correlating with something like SA timelog files)
104
    <li>Logging improved some more: Message-Id is added to log entries, as
105
        well as the full mailinfo whether the message is spam or not
106
    </ul>
107
 
108
<li>2003/04/30 - v3.0 (<a href="files/sa-exim-3.0.tar.gz">sa-exim tar.gz</a>
109
    or <a href="files/local_scan/local_scan.c_3.0">local_scan only</a>)
110
    <ul>
111
    <li>Makefile can generate a short sa-exim.conf (for Brian Kendig)
112
    <li>Added a contrib directory with 3rd party scripts
113
    <li>Since we already had X-SA-Exim-Rcpt-To: to show the envelope to
114
        (disabled by default), I added X-SA-Exim-Mail-From: to show the
115
        envelope from (always enabled, but you can delete it in system_filter
116
        if you wish). If you can't easily see or parse the envelope sender
117
        in your mails, this should definitely help
118
    <li>Much improved directory creation and error handling for the reject
119
        save directories
120
    <li>Added SIGCHLD patch from David Woodhouse
121
    <li>Added version header that looks like this:
122
        X-SA-Exim-Version: 2.2.x-cvs (built Tue Apr 22 10:28:25 PDT 2003)
123
    <li>Rewrote pretty much every log message to be more consistent and grepable
124
        (the previous ones were quite bad). Suggested by multiple people
125
        including Brian Kendig
126
    <li>Made the SMTP error messages finally configurable (suggested by
127
        several people). This is now possible since exim lets me output a
128
        different message in the log than in the SMTP session. Consequently, new
129
        default messages do not show the spam score, this only goes to the exim
130
        now.
131
    <li>Made SAmaxrcptlistlength and option to control how long of a
132
        X-SA-Exim-Rcpt-To header you can output if you want to output it at
133
        all
134
    <li>Do not output "savemail condition expanded to false" if not in debug
135
        mode (as reported by Brian Kendig)
136
    <li>Now ships with a sample local_scan.h if we can't find the exim source
137
    <li>Change of logic to delete SA headers that were in the original mail
138
        but weren't outputted by the SA run (like X-Spam-Flag, as reported
139
        by Chad Leigh)
140
    <li>Modified local_scan dlopen patch to deal with updates to the exim
141
        local_scan API
142
    <li>The default location for spamasassin.conf was changed to /etc/exim4
143
        (debian default)
144
    <li>Updated README and INSTALL
145
    <li>Updated localscan_dlopen.patch to deal with minor/major version numbers
146
    <li>Added X-SA-Exim-Version
147
    </ul>
148
<li>2002/10/28 - v2.2 (<a href="files/sa-exim-2.2.tar.gz">sa-exim tar.gz</a>
149
    or <a href="files/local_scan/local_scan.c_2.2">local_scan only</a>)
150
    <ul>
151
    <li>Fixed a bug that affected all mails bigger than what spamc would
152
        accept. Doh! (it not clear why, but spamc would hang and stop reading
153
        after it had been fed more than it was willing to accept)
154
    <li>Added more debugging code to help track the above problem
155
    <li>Depending on SATruncBodyCond will now either not pass a message that's
156
        too big to spamc, or will optionally truncate it first
157
    <li>Now strips any X-SA-Exim-* headers already present in the message before
158
        scanning it
159
    <li>Added new X-SA-Exim-Rcpt-To: header (see privacy section in README)
160
        after a suggestion from Brian Kendig
161
    <li>Teergrube is now spelled correctly (note that the option names in
162
        sa-exim.conf changed as a result)
163
    <li>Teergrubing has been re-implemented to detect that the other side went
164
        away so that exim doesn't stay around for nothing.
165
    <li>Added SAteergrubecond so that you don't teergrube your neighbours
166
    <li>Small cleanups
167
    </ul>
168
<li>2002/10/13 - v2.1 (buggy) (<a href="files/sa-exim-2.1.tar.gz">sa-exim tar.gz</a>
169
    or <a href="files/local_scan/local_scan.c_2.1">local_scan only</a>)
170
    <ul>
171
    <li>Default mail config is now in /etc/exim instead of /etc/mail
172
    <li>Fixed SAstallsender so that exim doesn't leave spool files behind
173
    <li>Fixed comparison for spam values as suggested by Patrice Fournier
174
    <li>Returned a header saying whether SA-Exim was able to scan the mail
175
        or not (based on a suggestion from Patrice Fournier)
176
    <li>Added support for teergrubing as suggested by Robert Strickler
177
        (see
178
        <A HREF="http://www.iks-jena.de/mitarb/lutz/usenet/teergrube.en.html">
179
        http://www.iks-jena.de/mitarb/lutz/usenet/teergrube.en.html</A>)
180
    <li>We now make sure that we feed spamc a little more data than it's
181
        willing to accept. That way, we don't feed a truncated message
182
    <li>sa-exim.conf now appends /new on save directories so that they
183
        are valid maildir spool and you can run mutt -f dirname to read
184
    <li>Small cleanups
185
    </ul>
186
 
187
<li>2002/07/07 - v2.0.1 (<a href="files/sa-exim-2.0.1.tar.gz">sa-exim tar.gz</a>
188
    or <a href="files/local_scan/local_scan.c_2.0.1">local_scan only</a>)
189
    <ul>
190
    <li>Removed unneeded ## concatenation in macro
191
    <li>Fixed lseek call, as reported by Peter N Lewis
192
    <li>Improved Makefile for documentation
193
    <li>Suggestion from dman to allow for config options overrides in Makefile
194
    <li>Fixed all the compiler warnings that were fixable
195
    <li>Handle more kinds of Message-Id as suggested by Patrice Fournier
196
    </ul>
197
 
198
<li>2002/06/14 - v2.0 (<a href="files/sa-exim-2.0.tar.gz">sa-exim tar.gz</a>
199
    or <a href="files/local_scan/local_scan.c_2.0">local_scan only</a>)
200
    <ul>
201
    <li>Allow for stalling SMTP sessions from spammers (caution)
202
    <li>Support X-Spam-Status from SA pre 2.30
203
    <li>Build patches from Norm <norm@sandbox.org.uk>
204
    <li>Documented that spamd shouldn't be run with -c
205
    <li>dman's patch to allow for this to be a shared library
206
    <li>dman's indirect request for saved files to be 660
207
    </ul>
208
<li><a href="files/local_scan/local_scan.c_2.0b1">2002/06/01 - v2.0b1</a><br>
209
    This is how 1.0 would have been if I had done it right :-)
210
    <ul>
211
    <li>We now attempt to create directories we write to
212
        (suggestion from Patrice Fournier)
213
    <li>Log envelope sender, recipients and connecting host
214
        on rejected messages (suggestion from Patrice Fournier)
215
    <li>We can now save non rejected messages whether they were
216
        flagged as spam or not (based on request from Patrice)
217
    <li>Each save rule now has its own condition that lets you
218
        decide which messages you want to save or not
219
    <li>Fixed parsing of Message-Id. May not parse all of them
220
        but won't do anything stupid with bad input
221
    <li>Fixed a buglet where we removed old headers before knowing
222
        whether they were going to be replaced.
223
    <li>Added much needed internal alarm so that we don't run
224
        too long
225
    <li>I added lots of options, but weren't able to test all
226
        of them and their combinations, please reports problems
227
        you may notice and documentation issues (in config file)
228
    <li>Thanks also go to dman for his plentiful feedback
229
    </ul>
230
<li><a href="files/local_scan/local_scan.c_1.3">2002/05/21 - v1.3</a>
231
    <ul>
232
    <li>We now close the files we create on disk. Duh!
233
    </ul>
234
<li><a href="files/local_scan/local_scan.c_1.2.2">2002/05/17 - v1.2.2</a>
235

236
    <li>SA options are now kept in memory. Small cleanups
237
    </ul>
238
<li><a href="files/local_scan/local_scan.c_1.2.1">2002/05/13 - v1.2.1</a>
239
    <ul>
240
    <li>v1.2 (unreleased) didn't work right: it tagged messages
241
        properly, but failed to see what was marked as spam and
242
        couldn't reject messages. Fixed.
243
    <li>Stripped newlines in header lines (better for logging)
244
    <li>fixed header_add bug if headers contained '%'
245
    </ul>
246
<li><a href="files/local_scan/local_scan.c_1.2">2002/05/12 - v1.2</a> (unreleased)
247
    <ul>
248
    <li>According to Craig R Hughes, any X-Spam header can be multiline.
249
        Let's parse them accordingly
250
    </ul>
251
<li><a href="files/local_scan/local_scan.c_1.1.1">2002/05/08 - v1.1.1</a>
252
    <ul>
253
    <li>Added fake envelope from to mails that we save on disk
254
        so that they can be opened with MUAs (idea from dman)
255
    </ul>
256
<li><a href="files/local_scan/local_scan.c_1.1">2002/05/07 - v1.1</a>
257
    <ul>
258
    <li>Cleaned up and fixed multiline header parsing
259
    <li>Added parsing of Subject back from Spamc (suggestion from dman)
260
    <li>We now log how long spamc took, and all messages processed
261
        by spamc get logged in mainlog so that we know the outcome
262
    <li>Added custom header compare function to handle mixed case headers
263
    </ul>
264
<li><a href="files/local_scan/local_scan.c_1.0.1">2002/05/06 - v1.0.1</a>
265
    <ul>
266
    <li>Fixed problems with reading Content-Type back from spamc
267
       (we used to read whole body too, ooops...)
268
    <li>Handle multi-line Content-Type headers.
269
    <li>All log entries now start with "SA: "
270
    <li>If SA gets run twice, we drop the previous X-Spam headers
271
    <li>Support for X-Spam-Prev-Content-Transfer-Encoding
272
    </ul>
273
<li><a href="files/local_scan/local_scan.c_1.0">2002/05/05 - v1.0</a>
274
    <ul>
275
    <li>*Many* changes. This is now a real program with hopefully
276
        most of the configuration options people could need
277
    <li>Fully configurable through external config file
278
    <li>Condition to run or not run SA against a message
279
    <li>3 Levels of spam handling
280
    <li>Option to save messages that are rejected or cause errors
281
    <li>Very complete error checking
