Local domain sending remote mail

One of my clients has Exchange 2000 on their local domain (company.local).  They use this for sending inner-office email.  Each user also has a POP3 account for their public email address (company.com).  As of late, some users are finding that email they are trying to send to somone remotely (user@place.ham) is trying to be sent through the Exchange server instead of their POP3 account.  Generally these get bounced back because reverse lookup by other servers of the domain (company.local) gets unresolved.  I have yet to find any consistancy with this, but it does send email to the same remote user at different times by a different account each time.  This Exchange server has been running for a few years without anything like this happening.  Also, I do have the clients set with the pop3 as the top priority for sending mail.  Is this an Exchange issue or an Outlook issue?  Also, can something be set, or was possibly changed, that configures the Exchange server to only offer local delivery?

Thank you.

I'm not too familiar with Recipient Policies, but if I make a new policy stating that user@company.com is an SMTP address, how will this be treated?  The exchange server is not an Internet available smtp server, nor a do they have a public domain name pointing to their IP address.  Can you give me more information on doing this?

Thanks.
It will be treated as an internal mail as long as there is a user with the right adress. If not it will be sent out on the internet. It will not need to be available on the internet, you only want it to send mail. As you already has found out that it does. The users will use the POP3 to receive mail from internet as normal.
Just change the default policy, and be sure to set @company.com as default

Okay, I understand that, but what happens when another public mail server tries to reverse lookup that mail?  My understanding is that it will just lookup from @company.com and not worry about the fact the email server is mail.company.local.  On the client side of things they have 2 email accounts.  One which is an exchange account and another which is a POP3 Internet email account.  Should I just set the Internet email accounts SMTP server as being mail.company.local and keep the POP3 server as being mail.company.com?

Thanks.

Okay,  I was just looking this over.  Sorry for repeating the question about getting POP3 from the Internet.  I missed that on your previous comment.  So,  If a user's @company.com email address is the same as @company.local I can just edit the default policy.  I know for a fact that one of the users Internet email address is firstname@company.com while their other account is FirstInitialLastName@company.local.  Am I correct by saying that in this case I would just create a custom policy for that user?

You have been very helpful.  I'm going to bump up the point value for you.

Thanks
Just create a custom policy for that user yes. Or just go in to the user and add an smtp adress and set it as default. Depends on how many users you have
But if all users have firstname@company.com, I would recommend changing default policy by just adding one more SMTP address. And making it default
