How you obtain the entries is up to you, but the included\nlogwatcher module provides one possibility.\n\nThe list is stored in a directory, each entry being a file (usually --\nzero sized) or a symlink (usually -- a \"broken\" one). Such entries are\nstored efficiently (within the directory itself) and the directories are\nsearched using the hash tables on modern file systems. At the same time,\nthey can be listed, added, and removed with the simple ls(1), touch(1),\nand rm(1).\n\nThis milter does not itself filter spam, instead it memorizes the\nverdicts issued by your other anti-spam defenses to reduce the system\nload and resource consumption, by temporarily rejecting the relays\nsuspected of spamming (banned) and, optionally, by permanently rejecting\nthe relays \"convicted\" of spamming (blacklisted).\n\nThe idea is to stem the spam from real spam sources, while reducing the\nill effects of false-positives to merely delaying, rather than rejecting\nfuture messages.","flavors":[],"html":"https://daemonports.org/mail/milter-skem/","kind":"port","lastUpdate":"2026-10-24T20:53:03+03:00","license":["SKEM"],"maintainer":"ports@virtual-estates.net","name":"skem","newest":true,"newestVersion":"1.0.3","noVulnData":false,"origin":"mail/milter-skem","otherSystems":[{"behindSince":"2026-10-24","maintainer":"ports@virtual-estates.net","origin":"mail/milter-skem","path":"/dragonfly/mail/milter-skem/","system":"DragonFly","version":"1.0.2_4"},{"behindSince":"2026-10-24","maintainer":"ports@virtual-estates.net","noVulnData":true,"origin":"mail/milter-skem","path":"","system":"HardenedBSD","version":"1.0.2_4"},{"behindSince":"2026-10-24","maintainer":"ports@virtual-estates.net","noVulnData":true,"origin":"mail/milter-skem","path":"","system":"GhostBSD","version":"1.0.2_4"}],"packages":[{"repo":"FreeBSD:14:latest","versions":["1.0.2_4","1.0.2_4","1.0.2_2","1.0.2_4","1.0.2_4"]},{"repo":"FreeBSD:14:quarterly","versions":["1.0.2_4","1.0.2_4","n/a","1.0.2_4","1.0.2_4"]},{"repo":"FreeBSD:15:latest","versions":["1.0.2_4","1.0.2_4","n/a","1.0.2_4","1.0.2_4"]},{"repo":"FreeBSD:15:quarterly","versions":["1.0.2_4","1.0.2_4","n/a","n/a","n/a"]},{"repo":"FreeBSD:16:latest","versions":["1.0.2_4","1.0.2_4","n/a","n/a","n/a"]},{"repo":"FreeBSD:16:quarterly","versions":["n/a","n/a","n/a","n/a","n/a"]}],"pkgName":"skem-1.0.3","related":null,"repository":"FreeBSD ports","requiredBy":[],"requiredByCount":0,"runDepends":[],"status":null,"system":"freebsd","systemLabel":"FreeBSD","version":"1.0.3","versions":[{"commit":"36dc228bb9bcb6835b8e830f0e359ae606c62c0c","date":"2026-10-24","version":"1.0.3"},{"version":"1.0.2"}],"vulnerabilities":null,"www":"http://virtual-estates.net/skem/"}
