WP Mail Problem

Good afternoon

I was wondering if someone could help, I am trying to get SMTP to work for our WP Forms Lite (using WP Mail SMTP) and I get the following error message:

Versions:
WordPress: 5.3
WordPress MS: No
PHP: 7.4.0
WP Mail SMTP: 1.7.1

Params:
Mailer: smtp
Constants: Yes
ErrorInfo: Invalid address: (setFrom) [email protected]
Host: localhost
Port: 25
SMTPSecure: string(0) “”
SMTPAutoTLS: bool(true)
SMTPAuth: bool(false)

Server:
OpenSSL: OpenSSL 1.0.2k 26 Jan 2017
Apache.mod_security: No
SMTP Debug:
Invalid address: (setFrom) [email protected]

How do I resolve the “Invalid adress” as this is our domain URL!

Thank you
