How about ps -ef | grep post ... ?

Heres what I get:


root 24027 1 0 20:57 ? 00:00:00 /usr/libexec/postfix/master
postfix 24029 24027 0 20:57 ? 00:00:00 pickup -l -t fifo -u
postfix 24030 24027 0 20:57 ? 00:00:00 qmgr -l -t fifo -u
root 24169 23889 0 21:39 pts/2 00:00:00 grep post

Thank you for helping me this far...

Ok, so I suspect your postfix is set-up to only work on
loop-back. Can you please attach your config files with
anonymised personal/sensitive information?

Just to confirm: can you repeat the netstat and lsof
commands, this time grepping for master, please?

I'm sorry I don't know what you are asking for...Could it be that I'm running CentOS as a virtual machine on a Win 7 box? Just throwing that out there...

I mean, this shouldn't be this difficult right? I should be able to just configure what I need for Postfix and it should run ok correct? Most people don't have this much trouble getting going right? Im just trying to gauge what's happening here. I'm quite confused. I don't think I've done anything out of the ordinary with my config so it's either got to be the fact that I'm running a Virtual box or my ISP. Postfix doesn't require so much tinkering right?

No, not much; but running in a VM begs the question whether or not
you're actually forwarding traffic to it, and it still looks as if
it's not listening on the machines "public" interface.

Please post
netstat -anp | grep master
output here.

Here it is:

That's quite an output. What should I be looking for?

Here's your problem. That's the localhost, your postfix won't talk/listen to
the world. If it did this should be (one of) the VMs actual network interfaces.

So how do I fix it? Please help.

But wait...port 80 is working fine. I'm running a webserver off this same box. WHy is is it just postfix that isn't working?

So ... post your sanitised/anonymised config files.

Im not quite sure how to get my main.cf file anonymized and into a web browser. I'm not a vi genius unfortunately. I think you might be trying to get to the inet_interfaces section though correct? I have all of that uncommented if that helps.

That will be a start
