email forwarding
 

I'm in an office without an exchange server... we are using Outlook
2003 for our mail. We have mail that has been established for some
time now through our ISP... but we also have email forwarders tied to
our domain. The outside world can be informed of our forwarders from
the domain name, but when we reply to them, they will see a different
address in our email header (the one from our ISP). Although I can
change the reply e-mail address so that they are still replying to our
domain mail, they may confuse the ISP address into their contact
managment.

I can add the domain email to the name in the account, but is there a
way to hide or change the signature of the ISPs address to our domain
forwarder? I know we can order a mail service, but we're a non-profit
and I'm trying to save as much money as possible.

Thanks for any help.
