Unable to verify CNAME record with my domain registrar, GANDI.NET!

Unable to verify CNAME record with my domain registrar, GANDI.NET!

This is how my DNS zone file looks:

@ 10800 IN A 217.70.184.38
62ff910ec18558a47d10ce32ecce2475 10800 IN CNAME f79addb959911bc875d0728b12df0e3ece8a3d12.comodoca.com.
blog 10800 IN CNAME blogs.vip.gandi.net.
imap 10800 IN CNAME access.mail.gandi.net.
pop 10800 IN CNAME access.mail.gandi.net.
smtp 10800 IN CNAME relay.mail.gandi.net.
webmail 10800 IN CNAME webmail.gandi.net.
www 10800 IN CNAME webredir.vip.gandi.net.
zb14905974 300 IN CNAME zmverify.zoho.com.
@ 10800 IN MX 50 fb.mail.gandi.net.
@ 10800 IN MX 10 spool.mail.gandi.net.
@ 10800 IN TXT "v=spf1 include:_mailcust.gandi.net ?all"

But when I ask ZOHO to verify it says it can't find the CNAME record.
