I have an email address with my cellular phone that I need my work address forwarded to. The only problem is, my cellular phone email address doesn't accept any messages unless they are addressed specifically to their address (not forwarded).
Example: Only works if addressed to 'firstname.lastname@example.org' - Doesn't work if email@example.com is forwarded to '443555....' because it goes to their system looking like firstname.lastname@example.org
So basically, I need to setup some sort of forwarding that makes messages appear as if they are addressed to one address, when really they are addressed to another. Any ideas?? Can this be done with Sendmail? Relaying? Masquerading?
