Google apps says: To use the custom URL mail.domain.com, you must change the CNAME record with your domain host. Find the CNAME settings and enter the following as the CNAME value or alias: mail Set the CNAME destination to the following address: ghs.googlehosted.com If I try and add a CNAME record and enter "mail" as name and "ghs.googlehosted.com" as hostname then I get this error: Data needs to end with a dot (.) What am I doing wrong? (I feel like I must just not be understanding something fundamental about how DNS records work)
