telnet: connect to address 92.205.28.224: Connection refused

I need telnet 92.205.28.224 587 to not get connection refused

I see telnet is an active service and port 587 is active on firewall. I also see 587 is open in the picture below.

services: dhcp dhcpv6-client http https imap imaps pop3 pop3s smtp smtps ssh telnet ports: 25/tcp 80/tcp 2224/tcp 587/tcp 8443/tcp 

To make port listener

netstat -an1p |grep 587 

To confirm port is listening

[root@buaidhnobas ~]# netstat -anlp |grep 587 tcp 0 0 0.0.0.0:587 0.0.0.0:* LISTEN 21018/nc tcp6 0 0 :::587 :::* LISTEN 21018/nc 

Now I should be able to telnet to 92.205.22.224 which is the problem I am trying to solve.

[Neptune@orcacomputers-com ~]$ telnet 92.205.28.224 587 Trying 92.205.28.224... telnet: connect to address 92.205.28.224: Connection refused 

So "something" is still blocking the port? I see telnet as an active service and port 587. So the port is open indeed.

 services: dhcp dhcpv6-client http https imap imaps pop3 pop3s smtp smtps ssh telnet ports: 7689/tcp 25/tcp 588/tcp 80/tcp 143/tcp 993/tcp 443/tcp 2224/tcp 587/tcp 8443/tcp 

Iptables turned off

[root@buaidhnobas ~]# service iptables status Redirecting to /bin/systemctl status iptables.service Unit iptables.service could not be found. 

Restart NetworkManager and attempt to telnet

[root@buaidhnobas ~]# telnet 24.149.185.150 587 Trying 24.149.185.150... telnet: connect to address 24.149.185.150: Connection timed out

Unable to telnet in,

What am I missing or not seeing? Both machines are RHEL
