Yes, but, what if someone types only the domain name into their browser? 
EX:  example.com

You might want to do this:

@       IN      MX mail.example.com.

@       IN      A       192.168.1.25
mail   IN   A   192.168.1.25
ftp   IN   CNAME   @
www   IN   CNAME    @
news   IN   CNAME   @


It is best for "mail" to have its own A RR to avoid having the RDATA of an 
MX RR reference a CNAME RR.
