Ive kind of been left on my own to get things working on a production linux box. Im happy because it gives me some true admin experience. But theres alot I dont know ...
Im trying to get mailx running. I can create an email, but it never gets delivered to my external email account.
I am running
Centos 6.4 Linux
Heres what Ive done/checked so far ..
server> mailq
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------

popeye@server.localdomain
popeye@mydomain.com

popeye@server.localdomain
popeye@mydomain.com

I then edit /etc/nsswitch.conf to change
hosts: files dns to hosts: files

So I guess my next two part question is
1. how can I confirm that port 25 is open on the server ?
2. how can I determine that there isnt a firewall blocking port 25 ?
Thanks!
