Hello everyone, I need your help. we are trying to configure the SMTP in a pc program to send confirmations and it gives error even putting all the configuration data correctly.
It turns out that putting the configuration for a Gmail account as proof that we have for Google applications, the same type of error comes out, but in this case in the Gmail mail an email arrives saying that it has been blocked for security.
Could it be that Cloudflare is blocking it? What I can do? Regards, and thank you very much.
