✨ amispammer(1) ✨ — the blacklist check bestie 🦋

🌸 NAME 🌸

okay so amispammer is literally the way to know if your MX IPs are blacklisted 💅 no cap, it's giving clarity 🫶

💖 SYNOPSIS 💖

amispammer [ -v 0|1 ] [ -i <IPaddress> | -d <domain> ] [ -T 0|1 ] [ -f
emailfrom -t emailto -s smtp_server ] [ -h ]

🎀 DESCRIPTION 🎀

okay so amispammer is a command line tool that checks whether an IP address or domain's MX IPs are currently sitting on any blacklist because of spam reports or bad reputation 😭 it's giving detective energy 🕵️‍♀️

the main target audience is system admins and security officers or consultants who want to check, from the terminal, whether an IP they're responsible for (or are auditing) is blacklisted 🧚 main character energy for sure 👑

to get the goods, amispammer checks over 90 popular blacklisting lists, the same ones used by almost every antispam professional device and software 🔥 literally the whole industry is looking at these lists, so we should too 💅

optionally, it can send an email to someone once it's finished checking the different lists where the IP address shows up 📧 this is SO useful if the task runs automatically at night, or even more often, in orgs where email is critical 🌈 and fr fr it only sends an email if the IP address appears on some blacklist, so no spam about nothing 🙈

🦋 OPTIONS 🦋

• -i — the IP address you want checked, in A.B.C.D format 💖
• -d — the domain to check 🌸 super handy when there are several MX records 💅

If you don't pass an IP or domain with -i or -d, amISpammer just assumes you want the public IP of the machine it's running on, and it detects that automatically 🫶

• -T — 0|1, which disables or enables the queries using threads 🧵 turning threads on makes things faster and cuts the query time, BUT it needs more memory and CPU 😭 by default -T 1 is enabled, so threads are on unless you turn them off 🔥
• -f — emailfrom, the email account (like sender@corp.org) that sends the email 💌
• -t — emailto, the recipient email account (like recipient@corp.org) that receives the email 💜
• -s — smtp_server, the SMTP server IP address where the email gets sent 📮 by default it's localhost 🏠
• -v — 0|1, the verbose level 🔊
  • 0 (the default if you don't specify anything) → only shows the blacklists where the IP address appears as listed 🙈 in this mode you can send an email with the results ✨
  • 1 → shows every single blacklist on the terminal along with the result of checking each one (blacklisted or not blacklisted) 🔍
• -h — asks for the program's usage info 🧚
