Hansen This is an ARexx-script for MailManager by Pino Aliberti. MM_AntiBomb checks the incoming mail-packets against the configured archivers. In case the packet is compressed with a known archiver, it compares the physical size of the packet with the size the packet would have if it was uncompressed. This compress-ratio is compared with a user configurable maximum ratio, if the compress-ratio of the checked packet exceeds this maximum, the packet is moved to the bad-directory, and a "BOMB_" is added in front of the packet-name. This way you can avoid filling your harddisk and crashing your system, if you receive a mailbomb. (A mailbomb is an archive, that isn't very big in size, but when uncompressed it will fill up to an unlimited number of megaytes! If your mailer tries to uncompress such an archive, it will eventually fill your harddisk, and your system will hang with the "device full - retry/cancel" requester.) :-( History of MM_AntiBomb ---------------------- 0.10 (04.05.96) Initial version --O-- Yours, Kent Hansen (kbh@imada.ou.dk) Team AMIGA Sysop TPV ============================= Archive contents ============================= Original Packed Ratio Date Time Name -------- ------- ----- --------- -------- ------------- 80 78 2.5% 04-May-96 14:25:20 File_ID.diz 2300 1150 50.0% 04-May-96 14:25:20 MM.info 2300 1150 50.0% 04-May-96 14:25:26 +Config.info 619 378 38.9% 04-May-96 14:25:30 +MM_AntiBomb.CFG 2300 1150 50.0% 04-May-96 14:25:26 +Docs.info 145 79 45.5% 04-May-96 14:25:40 +History.Txt 7585 3001 60.4% 04-May-96 14:25:40 +MM_AntiBomb.Doc 2300 1150 50.0% 04-May-96 14:25:26 +Rexx.info 7520 2881 61.6% 04-May-96 14:26:00 +MM_AntiBomb 7433 2489 66.5% 04-May-96 14:26:00 +MM_AntiBomb.rexx 7049 2411 65.7% 04-May-96 14:26:00 +MM_AntiBomb.rexx.cmp 2273 865 61.9% 05-May-96 16:17:34 MM_AntiBomb.readme -------- ------- ----- --------- -------- 41904 16782 59.9% 06-May-96 03:35:00 12 files
