SMTP predates Notes by nearly a decade.

More like 3 years, and in a very niche network that was not generally deployed in companies looking for email outside of certain niches.

SMTP is not a user interface. It’s just text from RFC821/822

Absolutely, but it came several years before MIME for example for formatted emails with attachments, and other things.

This. Any engineer or manager developing Notes at the time had to be aware of X.400 and X.500, and SMTP. They decided to ignore them. However cool and useful and clumsy Notes was, it was a proprietary walled garden. Lotus and the IBM hawked it, and surely profited. But for the customer it was an expense. Eventually Notes was overtaken by Metcalf’s Law, and the fact that cheaper always wins.

That and, you know, Microsoft.

Sure, but Notes was built for a world where ccMail, MS Mail, and GroupWise were the main workgroup email systems.

Notes followed a similar pattern, with a proprietary "post office" system with optional gateways to larger x.400 / SMTP / UUCP / OfficeVision networks for those who needed them.

Going SMTP (or even x.400)-native from the start might have been a better choice in the long run, but that's only clear in retrospect - it certainly wasn't obvious at the time.

Exchange is funny because it's X.400 native internally, even if recently they dropped external X.400 support

		Yeah, Exchange is a good comparator because it shows what the mail aspect of Notes might have been like had it been designed in the mid 90s rather than the late 80s. It's hard now to appreciate how different corporate IT was from the free-wheeling Internet world. The unexpected popularity of the web really did change everything.

in 1990 the internet was something talked about on your BBS as a mystical place you couldn't get access to except as a student. Lots of places had email, but it was unusual for anyone to be connected to any other system. Sometimes a BBS was part of fidonet, but that was rare (and there were many many less known networks).

Even if your typical big company did have a gateway for their internal email to other companies, odds are very few people used that gateway for business. If you wanted to communicate with somebody in a different company you dialed the phone or sent a fax.

On the other hand, anyone working on Notes would also be aware that its relationship with email is closer to today's Sharepoint than to today's Exchange. Email was one small aspect of a massive featureset; Notes was ahead of its time in terms of CRM/ERP/one-platform-for-everything that drives modern businesses like Oracle and Salesforce.
