💖 NAME 💖

okay bestie, so <pink>DMARC_U...FIX_LIST(1)</pink> lives in the User Contributed Perl Documentation section of your manual, and it's the home of dmarc_update_public_suffix_list — a command line tool to download updated public suffix list. yes, that's the whole vibe. she downloads, she updates, she slays. 🦋

✨ SYNOPSIS ✨

dmarc_update_public_suffix_list [ --option=value ]

that's it. that's the whole entrance. no cap. 💅

🌸 DESCRIPTION 🌸

so what she actually does is Downloads a new Public Suffix List to the location specified by /etc/mail-dmarc.ini. that's the assignment, and she ate. 💖

the PSL is maintained by the Mozilla Foundation. she gets updated a few times per month, and the devs are literally begging — you are requested to download no more than once per day. one a day, bestie. we do not spam the nice Mozilla people. 🙈

the URL of the file is

https://publicsuffix.org/list/effective_tld_names.dat

🎀 Options 🎀

dmarc_update_public_suffix_list [ --dryrun --help ]

  • random (--random) — introduce a random delay to spread server load. intended for use when running from crontab, so everybody doesn't show up to the party at the exact same second. 🫶
  • config-file (--config-file) — alternate config file path. you want a different config? say less. 🌈
  • help (--help) — print this syntax guide. she's helping. she's always helping. 💜
