SENDMAIL(8)

💌 SENDMAIL(8) — a mail enqueuer for smtpd(8) 🎀

okay bestie, welcome to the System Manager's Manual section, sit down, hydrate, we're doing mail 💅

✨ NAME ✨

sendmail — a mail enqueuer for smtpd(8) 🦋

---

🌸 SYNOPSIS 🌸

sendmail [-tv] [-F name] [-f from] to ...

---

💖 DESCRIPTION 💖

okay so the sendmail utility is a local enqueuer for the smtpd(8) daemon, and it's compatible with mailwrapper(8). it's giving ✨team player✨ fr fr.

The message is read on standard input (stdin) until sendmail encounters an end-of-file. that's it, that's the whole reading situation, she reads until you're done talking 🫶

and here's the thing — sendmail is not intended to be used directly to send mail. no ma'am. it's meant to be reached through a frontend known as a mail user agent. it's the backstage crew, not the main character 😌

Unless the optional -t flag is specified, one or more recipients must be specified on the command line. periodt.

The options are as follows, bestie, gather round:

• -F name — set the sender's full name. 🎀
• -f from — set the sender's address. 💌
• -t — read the message's To:, Cc:, and Bcc: fields for recipients. the Bcc: field will be deleted before sending. 🙈 (yes, actually deleted, that's the whole point of Bcc, bestie)
• -v — enable verbose output. she will NOT stop yapping and honestly? we love that for her 💅

To maintain compatibility with Sendmail, Inc.'s implementation of sendmail, various other flags are accepted, but have no effect. 💀

like. they're there. they're vibing. they do nothing. iconic behaviour honestly.

🦋 EXIT STATUS 🦋

The sendmail utility exits 0 on success, and >0 if an error occurs. so if you get a zero, she ate. if you get more than zero, something is lowkey wrong 😭
