Hey guys, I have a Centos 7 server on AWS. I have configured it for postfix and now am in the testing stage. I however cannot seem to telnet to the server using my public IP. I can connect to 25 locally however.

When I do a netstat i see that it is listening


[centos@mail ~]$ netstat -an | grep 25
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
tcp 0 64 172.31.36.223:22 104.54.198.229:61325 ESTABLISHED
tcp6 0 0 ::1:25 :::* LISTEN
udp6 0 0 :::22534 :::*
unix 3 [ ] STREAM CONNECTED 18025 /run/systemd/journal/stdout
unix 3 [ ] STREAM CONNECTED 6148625
unix 2 [ ] DGRAM 3709225


I am not sure what to check from here.

Any advice is appreciated.

thanks in advance

Jason

FYI, I found the issue. There was an error in my main.conf file.
