Client Access License for Exchange server

Is the CAL have anything to do with Email delivery and receivng e-mail to people outside the network.  In other words, how does this CAL for Exchange work/  If I don't have enough CAL, will it stop from receiving e-mail from outside the network.  How do we add the extra CAL in our Exchange server?

CALs for Exchange are done on the honour system. You should have enough CALs to cover every seat, as it is only licensed on a per seat basis.
The only thing that could enforce CALs is the licensing logging tool. This is generally regarded as a waste of time and most people disable it. In the event of an audit it would be ignored.
Lack of CALs would not stop you from receiving email from outside.

If you need to buy more CALs then purchase them in the regular way. If you are audited you need to provide the paperwork for those CALs.

This answer does NOT apply to SBS, where CAL use is hard enforced using the license tool as there is a hard limit of 75 in SBS.

Where do we find information about the server version and exchange version.
I have CDs for standard and Enterprise.  If I am using the Exchange enterprise, is there any chance of hard enforcement.

All the users I created now, are not receiving e-mail from outside.  Please see the reply I received?  Is this something to do with symantec mail security?
The e-mail system was unable to deliver the message, but did not report a specific reason.  Check the address and try again.  If it still fails, contact your system administrator.

Thanks for all the help.

The only product that hard enforces CAL limits is SBS. If you are not using SBS then you will not be hard enforced.
You can make double sure by disabling the license logging service.

If you have a Symantec product on the server then that is always the first place to look. I don't hide my hostility towards all Symantec products, particularly their antivirus products. That is based on experience - they do seem to cause more problems than any other product - even taking in to account their larger user base.
