I dont know if it's just me, but this comment is breaking the rendering of Voyager

[–] elvith@feddit.org 3 points 1 month ago

I needed to use a code block for that address as several apps had a problem when I tested escaping the back ticks in the address for the inline code. Not sure if you mean that as it renders in it's own line or if anything else is broken

Because of one smartass customer who insisted on doing exact RFC 822 validation, I implemented exactly that. And yes,

zKcknV|NGv.lI66vR#@X`QcRK4K.R`?NpA.Gc2Kqzue9.%&nb1kGWp/./#Och$RQv

is one of the test cases for a valid addr-spec. See (or generate) some others at https://github.com/mormegil-cz/rfcemailvalidator
