Adobe Portfolio connecting to my domain

[suemoseley]

I've built my website in Portfolio and I'm trying to connect it to my existing domain (not as a subdomain). I've deleted the A records @ and www and replaced them with the ones supplied by Adobe but I am getting the message 'Oops! Looks like you have an extra IP address set up. Please go back to your domain settings and remove any A Records not pointing towards Adobe Portfolio.'. My issue is that some of these A Records relate to my email service on this domain. Which of the existing A records on this list are necessary to delete in order for the site to work? sftp, ssh, mail, mailserver, ftp, mcp, smtp, webmail

Also, the only other DNS record I have set up is MX for the mailserver. I have no CName records set up.

Update: I didn't have to delete anything else, it sorted itself out after a couple of hours. However, now when I go to my website Google won't let me access it saying the site is not secure. Is this automatically dealt with? If so how long does it take?
