| 1 | Changes since 0.8.3 |
| 2 | ------------------- |
| 3 | Changed include() calls to require_once() calls. |
| 4 | Internationalization of the plugin. |
| 5 | |
| 6 | Changes since 0.8.2 |
| 7 | ------------------- |
| 8 | Added many new FREE anti-spam databases to lookup from. |
| 9 | Removed ORBS since they're off the air. |
| 10 | |
| 11 | Changes since 0.8.1 |
| 12 | ------------------- |
| 13 | Added a SpamFilters_DNScache[] array that is useful for 2 reasons: |
| 14 | |
| 15 | 1. You can put in IPs in the cache that override the SPAMfilter's DNS |
| 16 | checking routines -- either to force 'em to NOT filter email coming from |
| 17 | a specific IP (ie. for those pesky customers who can't figure out how to |
| 18 | make Exchange not be an open relay) or to force 'em to ALWAYS filter email |
| 19 | coming from a specific IP (ie. for those pesky sites you KNOW are SPAM |
| 20 | sources or relays but that aren't added to any of the DNS databases) |
| 21 | |
| 22 | 2. Before the SPAMfilters do a DNS query, they check to see if the IP in |
| 23 | question is already in the cache. If not and the query is performed, the |
| 24 | result is put in the DNS cache. This makes the SPAM filters a LOT faster |
| 25 | when you get lots of email from various mailing lists (all coming from a |
| 26 | very small number of IPs). The SPAM filters don't have to do a DNS query |
| 27 | on every message coming from the squirrelmail-plugins mailing list -- only |
| 28 | one the first time through to confirm the list server isn't in any of the |
| 29 | DNS databases! :-) |
| 30 | |
| 31 | Changes since 0.8 |
| 32 | ------------------- |
| 33 | Just fixed the Bad or malformed FETCH error that occurred when the INBOX was |
| 34 | empty. The spamfilter plugin did a FETCH query from MsgNum 1 to * and since |
| 35 | there WAS no Msg Num 1 the IMAP server would respond with an error. Now I |
| 36 | check the number of messages before calling spam_filters or user_filters |
| 37 | |
| 38 | Changes since 0.7 |
| 39 | -------------------- |
| 40 | Tyler made TONS of changes to incorporate the fixes I'd done and posted |
| 41 | about, as well as to fix the problem with number of unread messages not |
| 42 | showing up in the folder panel. He also added some code to scan the headers |
| 43 | for specific IPs in order to scan only IPs on the previous hop in the |
| 44 | header. |
| 45 | |
| 46 | This didn't work well for me (the IP of my gateway wasn't reported on the |
| 47 | Received from ... by ... line, and so RSS and DUL still had tons of false |
| 48 | hits. I munged it so instead it uses a single string provided at |
| 49 | setup/install time to find the right line in the header to find the IPs to |
| 50 | look for in the various databases. (see SpamFilters_YourHop in setup.php) |
| 51 | This seems to work pretty well for me -- faster enough to turn on all the |
| 52 | databases and zero (so far) false hits! (grin) |
| 53 | |
| 54 | I also found a bug in sqimap_read_data() in functions/imap_general.php. |
| 55 | After much discussion with Tyler, I rewrote it and posted it to |
| 56 | squirrelmail-devel but it hasn't been accepted/tested/blessed yet |
| 57 | NOTE: THIS NEW VERSION OF sqimap_read_data() IS REQUIRED BY FILTERS 0.8 |
| 58 | so you'll have to edit functions/imap_general.php and replace the function |
| 59 | with the contents of sqimap_read_data.php. |
| 60 | |
| 61 | As soon as either my version of sqimap_read_data is officially part of the |
| 62 | SM 1.1.2 CVS or until a new working version is posted, this is the only way |
| 63 | to guarantee filters 0.8 will work. |
