Domain epic fail.

[JoeK]

The domain bnc4free.com is having problems with making CNAMES (look for yourself, pop3.bnc4free.com smtp.bnc4free.com) and they arent resolving, the general A records resolve but otherwise it dosent resolve cnames.

You don't allow axfr transfers so I can't see your zone file. So this is only a general answer:

Remember that if you've got a CNAME for anything on the left side, then you can't have anything else referring to the same left side value, on either the left or right side.
