Since your SMTP proxy is turned off, you should be able to configure a test client on the internal network to send email out through your ISP directly.  I'd do this in order to triple-check that I had the correct username and password values...

Client can send email out trough ISP directly. I found that ISP smtp reject connection from server because my SME server use system name 'mysmeserver.my-isp.com' that can't resolve by ISP smtp.

Code: [Select]

Net::SMTP=GLOB(0x8ea2f90)>>> HELO mysmeserver.my-isp.com
Net::SMTP=GLOB(0x8ea2f90)<<< 550 Forged HELO: you are not mysmeserver.my-isp.com

My workaround was change code on /usr/local/sbin/smtp-auth-proxy.pl. For some reason I can't change my server system name, so I change Hello value to 'localhost'.

Code: [Select]

my $smtp = Net::SMTP->new($smarthost,
                            Hello => 'localhost',
                            #Hello => "${system_name}.${domain_name}",
                            Debug => $debug
                        );
    unless ($smtp)
    {
        print "451 Upstream SMTP server not available\n";
        warn "No SMTP connection to ISP server\n";
        exit;
    }

Any other idea?

Thank's

Did you try to change the system name by login in to a SME Server shell as admin (with the same password as the root user). You will be presented a menu, where you can choose to reconfigure your system and in th first step you should be able to change the name of your server.
