NULLMAILER-SMTP(8)

✨ nullmailer-smtp ✨

ok so bestie, welcome to nullmailer-smtp(8) — it's the smtp mail sender for nullmailer, and honestly? it's giving "tiny little workhorse that just does its one job and does it well" 💅

🌸 NAME 🌸

nullmailer-smtp — the smtp mail sender for nullmailer. that's it, that's the vibe. 🦋

🎀 SYNOPSIS 🎀

/usr/lib/nullmailer/smtp [flags] remote-address < mail-file

so you run it, you hand it a remote-address, you feed it a mail file on stdin, and it goes and does its thing. the < mail-file part is lowkey the whole point — it reads the message from standard input. 🍓

💖 DESCRIPTION 💖

it sends an email message via SMTP. periodt. ✨

👑 OPTIONS 👑

here's the full menu, no skips, no cuts, we're listing all of them because that's what we do 🫶

• -p, --port=INT — sets the port number on the remote host that it should connect to. you know, the door you're knocking on 🚪
• --user=VALUE — sets the user name for authentication
• --pass=VALUE — sets the password for authentication. keep this one secret bestie, no posting it in the group chat 💀
• -d, --daemon — use syslog exclusively. only syslog. nothing else. it's giving committed 🎀
• -s, --syslog — use syslog additionally. like, on top of whatever else it's doing 🌈
• --auth-login — use AUTH LOGIN instead of auto-detecting in SMTP. sometimes you just gotta tell it what to do 🦋
• --ssl — connect using SSL (on an alternate port by default). sparkly and encrypted ✨
• --starttls — use the STARTTLS command. upgrade the convo mid-chat, iconic behavior 💅
• --x509certfile=VALUE — the client certificate file
• --x509cafile=VALUE — the certificate authority trust file (defaults to /etc/ssl/certs/ca-certificates.crt). that's the fallback if you don't say anything 📜
• --x509crlfile=VALUE — the certificate revocation list file. the naughty list, but for certs 🚫
• --x509fmtder — the X.509 files are in DER format (defaults to PEM format). so if you don't pass this, it's assuming PEM, got it? 💜
• --insecure — don't abort if the server certificate fails validation

⚠️ okay real talk for a sec — --insecure literally means it will NOT bail out when the server's certificate fails validation. that's a security thing, not a cute lil quirk. use it with your eyes open 🙈

• -h, --help — display this help and exit. the classic. the icon. the "help me" button 🌟
