I know that Exchange is working tightly with AD and DNS.
My question is how tightly?

I can send e-mail to the internet , i can send e-mails
internally , but cannot receive any.

I have a static IP address set on the ADSL adapter on my
server and an internal IP on the NIC.

I think it is to do with the way i setup DNS, but i am not
sure.My zone is created , although i am not sure about the
MX record(meaning which IP?)

Or is it my ISP messing with me?

Has anyone got any idea?

Any advice will be welcome as i spent
already two weeks on it. If you need any info regarding
settings or else don't hesitate letting me know.

Thanks in advance.

You should have an MX record in your public DNS zone, that MX record should
have the FQDN (not IP address) of your mail server (i.e. mail.domain.com)
The field labeled Host or domain should be left blank on that record.
Also, in that zone you need a host record named mail giving it the public IP
address of your mail server.

Also, you must have a reverse lookup (PTR) record for the public IP of your
mail server giving the FQDN of your mail server. Your ISP will most likely
have to host this record for you since their DNS server is most likely
Authoritative for your Reverse Lookup on your IP Address. To verify the
reverse lookup on your IP address goto www.dnsstuff.com and run a reverse
lookup on your IP address, you should be able to tell who is authoritative
for your address.
