Nerd sniped myself by trying to use PostfixAdmin from @mwl Run Your Own Mail Server, but the version in Ubuntu is from ages ago and the debian packaging mechanism seems to have been unmaintained for a number of years so I forked the upstream and hacked it to minimally work on my machine.
Also trying to simultaneously use Postfix in multi-instance mode, which is not covered in #RYOMS, but if something is worth doing it's worth overdoing, I guess.
Like I didn't have enough unshaved yaks already.
@daedalus gawd! I remember running postfix. I’m going to need some quiet time now. *shudder*
@bigjsl @daedalus “Sendmail”
@drscriptt @bigjsl sendmail.cf without m4 macros

@daedalus @bigjsl I was thinking that, but didn’t say it.

I cut my teeth on sendmail.cf with m4 macros.

So I didn’t want to mention something I’ve not administered.

@drscriptt It was a diabolical thing to have to do, really, all that line-noise-esque syntax. And yet it worked, more or less.
