💖 SENDMAILCONFIG(8) 💖

okay bestie, so this is sendmailconfig from the System Manager's Manual section 8 — yes she's a system manager page, very grown-up, very "I have root and I'm not afraid to use it" energy 👑

✨ NAME ✨

sendmailconfig — configure sendmail for Debian systems 🫶

🌸 SYNOPSIS 🌸

sendmailconfig [--no-reload]

🦋 DESCRIPTION 🦋

so sendmailconfig exists to make configuring sendmail(8) on Debian systems so much less of a whole thing. it's giving "let me handle this for you, bestie" 💅

in the simplest case, you can just run this program to (re)configure sendmail for your Debian system at literally any time you want. no big ceremony. it will modify the file /etc/mail/sendmail.mc in order to create a working sendmail configuration, and that working configuration gets written out to the file /etc/mail/sendmail.cf. iconic behavior, no notes ✨

now for the advanced girlies: you can modify the sendmail.mc file before generating sendmail.cf. and here's the part that's lowkey important — future invocations of sendmailconfig will preserve these changes, provided they are made at the end of the file. so if you put your edits anywhere else, don't come crying to me, bestie 😭 the end of the file is the vibe. that's the spot. iykyk.

normally sendmailconfig will ask if you want to reload sendmail after making changes to its configuration — very polite of her, honestly. and the --no-reload option will avoid this question entirely. she just won't ask. she'll mind her business. 🎀

🎀 FILES 🎀

and that's the whole page, bestie!! this one's from way back on 21-Jan-1997, and it came to us from the System Manager's Manual — so like, respect the elders, she's been doing this since before most of us could type 💀🦋 mwah, go configure something 💖
