CLI comand fails "check_if_email_exists someone@gmail.com"

[edigeze]

Email Provider

gmail

Version of check-if-email-exists (if running it yourself)

V0.9.0 check_if_email_exists-i686-pc-windows-msvc.tar.gz

What happened?

After installing the .exe file I run the following command: check_if_email_exists someone@gmail.com

I got this error:
"message": "io: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. (os error 10060)"

I am on windows 11.
I added Inbound Rule on port 25 to always allow connection.

Relevant log output

Are you running from a server with port 25 open, or from your local computer? Most ISPs block port 25.
