It's generally not the direct-to-consumer hosting companies but the B2B and corporate e-mail world where one might find that this isn't the case, and minus and plus are just considered ordinary characters as of old.

There was a FediVerse post, alas that I did not bookmark, about a month ago where someone found yet another WWW site that didn't allow the plus character in its sign-up forms that require mailbox names. Still happens.

... that is not strictly true. It depends from how local delivery works and what MTS is in use. Some mail systems do this, others do not.

It was an invention of the 1990s, long after the invention of Internet mail itself. Not everyone copied it; it wasn't a plus sign originally; and some WWW site softwares that don't parse mailbox names correctly even end up mangling or outright rejecting it.

@wild1145 Spot the #Postfix user. (-:

Minus and (later on) plus as extension delimiters have been commonplace since the 1990s. People should really be able to cope with them by now.

#InternetMail

The hardest part of setting up a #Mastodon instance is configuring #Postfix to send email with DKIM so they don't immediately end up in spam.

Wenn der Server hier nicht genutzt wird, habe ich wenigstens gelernt, wie man #Postfix einrichtet.
