So if the mail does not get into the inbox of your friend, this is not the fault of your mailserver but of gmail.
You can not do anything at all here. BUT I had a similar issue a few weeks ago where a client wanted to forward some mails through our mailserver to his gmail account. He did a lot of testings but no email came to his gmail inbox. I could just explain the very same as above, that our server did everything it should and that the problem resides on gmails side. He did not believe this so i did some testings with GMX and with my private mail server. And there everything worked like a charm. But he still believed, that the fault had to be on our side. It turned out, that gmail silently discarded all emails coming from mail accounts that where configured to be "sent as" by gmail. So when he had set (i just translate this from german, so it could be they are named differently) Gmail -> Settings -> Accounts and Import -> Send as: with some email addresses (not gmail, they where all from other providers) and then sent a testmail from one of these (other providers) accounts through our server (i know, who does such things?) they got silently discarded. Maybe something like this is the same problem here?
