1 | Changes since 0.8.3 |
2 | ------------------- |
3 | Just changed include() calls to require_once() calls. |
4 | |
5 | Changes since 0.8.2 |
6 | ------------------- |
7 | Added many new FREE anti-spam databases to lookup from. |
8 | Removed ORBS since they're off the air. |
9 | |
10 | Changes since 0.8.1 |
11 | ------------------- |
12 | Added a SpamFilters_DNScache[] array that is useful for 2 reasons: |
13 | |
14 | 1. You can put in IPs in the cache that override the SPAMfilter's DNS |
15 | checking routines -- either to force 'em to NOT filter email coming from |
16 | a specific IP (ie. for those pesky customers who can't figure out how to |
17 | make Exchange not be an open relay) or to force 'em to ALWAYS filter email |
18 | coming from a specific IP (ie. for those pesky sites you KNOW are SPAM |
19 | sources or relays but that aren't added to any of the DNS databases) |
20 | |
21 | 2. Before the SPAMfilters do a DNS query, they check to see if the IP in |
22 | question is already in the cache. If not and the query is performed, the |
23 | result is put in the DNS cache. This makes the SPAM filters a LOT faster |
24 | when you get lots of email from various mailing lists (all coming from a |
25 | very small number of IPs). The SPAM filters don't have to do a DNS query |
26 | on every message coming from the squirrelmail-plugins mailing list -- only |
27 | one the first time through to confirm the list server isn't in any of the |
28 | DNS databases! :-) |
29 | |
30 | Changes since 0.8 |
31 | ------------------- |
32 | Just fixed the Bad or malformed FETCH error that occurred when the INBOX was |
33 | empty. The spamfilter plugin did a FETCH query from MsgNum 1 to * and since |
34 | there WAS no Msg Num 1 the IMAP server would respond with an error. Now I |
35 | check the number of messages before calling spam_filters or user_filters |
36 | |
37 | Changes since 0.7 |
38 | -------------------- |
39 | Tyler made TONS of changes to incorporate the fixes I'd done and posted |
40 | about, as well as to fix the problem with number of unread messages not |
41 | showing up in the folder panel. He also added some code to scan the headers |
42 | for specific IPs in order to scan only IPs on the previous hop in the |
43 | header. |
44 | |
45 | This didn't work well for me (the IP of my gateway wasn't reported on the |
46 | Received from ... by ... line, and so RSS and DUL still had tons of false |
47 | hits. I munged it so instead it uses a single string provided at |
48 | setup/install time to find the right line in the header to find the IPs to |
49 | look for in the various databases. (see SpamFilters_YourHop in setup.php) |
50 | This seems to work pretty well for me -- faster enough to turn on all the |
51 | databases and zero (so far) false hits! (grin) |
52 | |
53 | I also found a bug in sqimap_read_data() in functions/imap_general.php. |
54 | After much discussion with Tyler, I rewrote it and posted it to |
55 | squirrelmail-devel but it hasn't been accepted/tested/blessed yet |
56 | NOTE: THIS NEW VERSION OF sqimap_read_data() IS REQUIRED BY FILTERS 0.8 |
57 | so you'll have to edit functions/imap_general.php and replace the function |
58 | with the contents of sqimap_read_data.php. |
59 | |
60 | As soon as either my version of sqimap_read_data is officially part of the |
61 | SM 1.1.2 CVS or until a new working version is posted, this is the only way |
62 | to guarantee filters 0.8 will work. |
