I assumed this was a Centos 7 mailing list and I was looking for help with IPTABLEs.I have used mailing lists before. Copying a file to an email address didn't have that type of output. I apologize.
First of all is this a Centos 7 Mailing list that I can ask for help or have I made a huge mistake? IF so, should I just attach the file to the email.
I apologize for the output, I had no idea. That's not the way it looked when I sent it.
I am sorry. I am just looking for some help with IPTABLES on Centos 7.
Please let me know and I won't send any more questions if I am not sending to the right list for help and not the right way.

Steve,
Do you have any idea of what you're writing? Why are you emailing -
this *is* an email list - with run-on lines? I mean, really, can you
read what you sent, below?
