Port 443 of computer isn't accessible to forum.cloudybots.com?

Alright I fixed it. I created an admin account.. but emailing now doesn’t work.

I used one.coms smtp send.one.com
Then I used their port (default)
Then I put the username spear@laverdecafe.com as I want that to be the email.
Then I put the password in where I normally login with that email.

But nothing…
