    Phoenix,
    tnx for fast response.

    My goal is to achieve access (send and receive) with mail client from any location. Big boss wants to send e-mail from anywhere. There is no way to explain him that is very insecure way for our corporate mail server.
    How I do open smtp from any location and ban others (spammers)?

    Regards

    I've already given you the answer to that. The correct port to use for mail submission is port 587 (not port 25), that requires authentication and will allow the user to send mial from any location via any mail client. Your users can also send mail from any location by using the Web UI. No changes are needed to ZCS for that scenario (unless you're on an older vserion of ZCS where port 587 wasn't open by default).

    I am still have a problem to send e-mails from open relay destination (from ip address which is not in zimbraMtaMyNetworks). I've used port 587 and received 421 error cannot connect to SMTP server. My firewall is open for tcp 587 and I can telnet from remote loaction on this port.

    telnet smtp.xxxxx.com 587
    Trying x.x.x.x...
    Connected to smtp.xxxxxx.com.
    Escape character is '^]'.
    220 mail.xxxxxx.com ESMTP Postfix

    Regards

    Then I guess you've an incorrect configuration in your email client for either (or both) the inbound and outbound server configuration.

    You should look in the log files to see what errors you're getting.

    Ok, finally I find what was the problem. When I was connected from outside on port 587 (which I opened on my firewall) actually, tcp connection was made on port 465 (SMTP over SSL) and when I opened this port on my firewall everything was ok.

    Tnx Phoenix for help

    Best Regards
