    Hello all!
    I have server behind FQDN GW. Server has not routeble ip (10.10.10.10) and my trouble is that domains who check my host name (or username?) reject my messages.
    Code:
    SMTP error from remote mail server after RCPT TO: <user@domain.net>: host domain.net: 451 Sender verification faild for my_user@my_domain.net
    Any ideas?

    You need to set the sender's domain (*@my_domain.net) correctly. It looks like it's currently using a fake domain and the recipient thinks you're a spammer.
