Exchange 2003 External users cannot Reply To

Current Setup:
Exchange 2003 server has third party POP3 client that retrieves email
from email server. (Don't yell at me...this is how it was setup prior
to my being here!). Client refers email to Exchange, then user
retrieves messages using Outlook. Outgoing using SMTP.

The issue:
Logins and internal mail looks like this...

jsm***@company.com

Internal emails back and for work fine, incoming and outgoing.
However, the person that setup the email accounts for the company,
setup the external mailboxes as:

joe.sm***@company.com

If external users send email using the joe.smith email, POP3 refers to
Exchange alias properly and internal user gets message. Internal user
replies to message and does get sent out external user. However, if
external user tries to reply on that message, they get an error "No
such user" as the Reply To address now has the internal email.

I'm being dumb here, but can't remember how to fix this.
Can anyone help me here?

Most likely you are going to have to change the internal Exchange address to
match the external address. Not sure why this was setup originally with two
different mail addresses. I would explain to the company the benefit of
having Exchange host the SMTP mail and dump POP3.

Agree...I was hoping there was a workaround..my assumptions were
incorrect.
Unfortunately, I work for a company where the "sys admin" (and I use
the term loosely) took it upon himself to do things his way and
doesn't understand the consequences of his actions. I'm sure everyone
knows that kind of person.

Thanks for your help anyway.
