Gerroald,
Yes, it was added to the ban list. It looks like it finally stopped when I got the host to ban the IP from the server entirely.
Yes, it was added to the .htaccess file as well. Our email (which is a different domain, this is a client account) is handled through gmail for business, so I’m not sure where the error logs would be for email, unless it’s some type of outgoing email log you mean for that domain?
Thanks
