When a message is forwarded through an intermediate\nserver, that intermediate server may need to rewrite the return-path to\nremain SPF compliant. If the message bounces, that intermediate server\nneeds to validate the bounce and forward the bounce to the original\nsender.\n\nSRS provides a convention for return-path rewriting which allows\nmultiple forwarding servers to compact the return-path. SRS also\nprovides an authentication mechanism to ensure that purported bounces\nare not arbitrarily forwarded.","flavors":[],"html":"https://daemonports.org/netbsd/mail/p5-Mail-SRS/","kind":"port","lastUpdate":"2026-07-16T19:01:23Z","license":[],"maintainer":"pkgsrc-users@NetBSD.org","name":"p5-Mail-SRS","newest":true,"newestVersion":"0.31","noVulnData":false,"origin":"mail/p5-Mail-SRS","otherSystems":[{"maintainer":"perl@FreeBSD.org","newest":true,"origin":"mail/p5-Mail-SRS","path":"/mail/p5-Mail-SRS/","system":"FreeBSD","version":"0.31_2"},{"maintainer":"perl@FreeBSD.org","newest":true,"origin":"mail/p5-Mail-SRS","path":"/dragonfly/mail/p5-Mail-SRS/","system":"DragonFly","version":"0.31_2"},{"maintainer":"perl@FreeBSD.org","newest":true,"noVulnData":true,"origin":"mail/p5-Mail-SRS","path":"","system":"HardenedBSD","version":"0.31_2"},{"maintainer":"perl@FreeBSD.org","newest":true,"noVulnData":true,"origin":"mail/p5-Mail-SRS","path":"","system":"GhostBSD","version":"0.31_2"}],"packages":[{"repo":"NetBSD 10.1 x86_64","versions":["0.31nb22"]},{"repo":"NetBSD 10.1 aarch64","versions":["0.31nb22"]},{"repo":"SmartOS / illumos x86_64","versions":["0.31nb22"]},{"repo":"macOS 15 arm64","versions":["0.31nb22"]}],"pkgName":"p5-Mail-SRS-0.31nb22","related":["mail/libsrs2"],"repository":"pkgsrc","requiredBy":[],"requiredByCount":0,"runDepends":["databases/p5-MLDBM","lang/perl5","security/p5-Digest-HMAC"],"status":null,"system":"netbsd","systemLabel":"NetBSD","version":"0.31nb22","versions":null,"vulnerabilities":null,"www":"https://www.libsrs2.org/"}
