Re: [webmin-l] Virtualmin Email Doesn't Work

    Dave, I tried your suggestions; result below.  I am still unable to
    telnet to the Postfix server on port 25; I get connection refused. 
    I don't understand why Postfix is not responding with the hello
    command.  Maybe it is some simple thing I am overlooking, I just
    don't see what is wrong.  By the way, telnet to Dovecot on 110;
    dovecot responds with a validation error.  I am stuck without an
    answer; I just don't know where to go; what to check, why this is
    failing.  I am thinking of removing firewalld; can it block even if
    shut?  I prefer iptables as a firewall and know how to configure
    it.  The only thing I can think of is that the firewall is not
    allowing even when it is not running; which is a strange thing.  I
    don't know if it is the firewall that is giving me the connection
    refuse status or Postfix.  Normally when I set up iptables, I don't
    let it report back the status; someone trying to gain access through
    a port won't get any message about being refused. Please help someone!
