Explanation of How To Forward Emails Without Server Access, Only With FTP Access

I am not a programmer or techie person. I have a website I have been volunteering to help with that is on an unknown server. I only have FTP access, not access to the server. I want to forward the emails that come to me to my gmail address. But I don't know how. I tried doing it in gmail, but I still don't get the messages. I need someone to explain to me how to do it. I can't give anyone FTP access since it isn't my site, so I just need a step by step explanation of how to do it myself. Thanks. ## Deliverables Explanation and functioning forwarded emails. ## Platform Using Dreamweaver and Firefox
