Re: can't get postfix to send to google

Gmail checks if you have a valid hostname (ie. an existing DNS record) and if that's not the case it drops the connection. It's a simple anti-spam measure, I use it on my postfix-based mail server too.
You should adjust your postfix configuration and even better use domain masquerade and relay your mails through your ISP's smtp server. Search google (irony ) for HOW-TOs.

Re: can't get postfix to send to google

Yes, there are two possible ways to do this. You could go directly to the google smtp server and create a dyndns domain, or you can go through your ISP's server. In my case, I just use my ISP's server because it is an open relay to members within their network. You have to be careful with SMTP and isp's because some block port 25 incoming, which could keep your server from recieving mail (which could affect you depending on hat you intend to do).
