isp bounces forwarded mail to gmail

Hi
I am running Fedora Core 8 as my mail and proxy server. My mail works properly for all users, but the problem I'm having is that when I create an alias for user's email to be forwarded to their gmail, the ISP bounces the mail. My ISP has given me an open relay to send mail.Is there somewhere in sendmail that I could put the user name and password of the ISP, so that the ISP will not bounce the forwarded mail. Or is there something that I'm missing?

Most likely GMail itself is bouncing it back (check and make sure what exactly happens). If I am correct, then you might need static IP and reverse DNS record for that IP to mach your servers hostname. There is error code in your servers mail log when bounce occurs. Read it and find what actually happens.
