Few questions:

1. Is your forum on a Shared web hosting, or a VPS/Dedicated server?
2. Is it using a Shared IP or a Dedicated IP?
3. Which mail delivery method you're using – PHP, SMTP or SendGrid?
4. Is your web server blocking any outgoing SMTP connections/ports, or enforced with any firewall rules or advanced anti-spam modules?
5. Is your Outgoing Email Address allowed to send Emails?
6. Whether the mail sending issue is with Gmail/Outlook, or with others/all?
7. What show up in the Email Error Logs?

Try with Gmail SMTP:

SMTP Host: smtp.gmail.com
SMTP Protocol: SSL/TLS
SMTP Port: 465/587
SMTP Username: your Gmail/Gsuite email
SMTP Password: your Gmail/Gsuite password

Make sure:

• Port(s) 465 or 587 are not blocked
• Less secure apps is Enabled: https://myaccount.google.com/lesssecureapps
