Hi
If your public domain is = to your internal domain, you must manually create
the pointers for the public access.
Example:
your webmail access is = webmail.domain.com
your internal ipaddress for domain.com is = 192.168.0.254 and the ipaddress
for the webmail.domain.com = 81.90.254.20, to solve this you can create a a
record named webmail.domain.com = ipaddress = 81.90.254.20, you can also
create a cname record but you must create first the A record that
identiffies that server, confused? let me explain:

Problem:
you need to redirect that users to the correct server on your isp for the
following services:
OWA, mail and pop server.
1- Create an a record named myisp.domain.com with the ipaddress =
81.90.254.20
2 - Create 3 CNAME records named webmail, smtp and pop, when you're creating
these records you're asked where you want to map these records to, you
choose the previous created record named myisp.domain.com.
3 when the users type in IE webmail.domain.com, they'll be redirected to the
81.90.254.20, the same happens to the outlook settings when you place the
smtp.domain.com and pop.domain.com.

Note:Generally the CNAME records are used for round and robin feature, but
you can also use it for this scenario or you can create a different A record
with the proper ipaddress:

webmail.domain.com = 81.90.254.20
smtp.domain.com =81.90.254.20
pop.domain.com =81.90.254.20
