I used to have an old PHPMailer and it worked well, but since PHPMailer developers did an upgrade, my old package stopped working, it required me to upgrade and I did. But as the athletic association has a different domain, it requires to enable SMTP. It failed, due to CA lack. I had to add Paragonie, modify php.ini to adjust openssl.cafile=, etc., and nothing worked.
I am looking for a simple and less complicated PHP form contact alternative, without these "all friends" (SMTP, third parties, etc.).

You have to believe in things that are not true. How else would they become?
There are a lot of mailer services out there, mailgun and SendGrid being two of them (disclaimer: Iʼm a user of both services).
SMTP is a good thing, if you have an in-house SMTP server that you can use for this. However, setting up an SMTP server is a real burden, especially if you want to do it right, so a lot of sites use such mailing services.
If I were you, I would go and discover these services to find which one fits the needs of the projects best.
