I have noticed that a certain IP address visits my email server via https. I allow https for webmail. I did a whois on it and it is a company called Netcraft Limited. Is this normal traffic? I am including the log file from my firewall thanks. I cannot seem to paste the image I wanted. However it is just showing the connect as well as the bytes sent and recieved.

whois 194.72.238.62
