the problem is that freemailers (google, yahoo, ...) do not want us to send mail on their behalf (call it "lock in" or call it otherwise). google have an spf record. yahoo sign their mail with dkim, ... etc. so you'll have problems if you want to forward such mail. Unfortunately, you can only do that by paying "whitelisted" ESP services. otherwise, rewrite addresses (aka SRS).
