I mean don’t do it if you don’t know about DNS, all the added antispam like SPF, IP blocklists and how the big players handle that. And don’t make any configuration mistakes and become an open relay for spam. It’s certainly doable, though. (With the proper Linux admin skills.)

And I want that technology for my personal use as my own assistant/secretary.
