A few questions

[swingline99]

I notice that all mail sent from server goes to junk whats the best way to keep this from heading to users junk mail? Also is there a good how-to I could read about configuring mail correctly? I seem to not be able to get this working 100% I think I got it accidentally work right with zpanel but I would like to better understand what Im mucking about with.

Thanks

I am facing the exact same problem.
Sometimes i even got delay on the emails.
And on some private email companies the emails do not reach the costumer at all.

If anyone knows a little more about this, please share it.

Thanks.

There are a few things to check/setup. You need to add an SPF record, (There are quite a few creators on Google: http://www.spfwizard.net/)
You also need to make sure your IP is not blacklisted (Again, there are many resources on Google to check it.)
Start with those and we will see how far you get
*This is still not guaranteed to work though. There are a lot of factors involved.
You can also Google how to fix it for even more info related to your specific install.

Make sure the PTR record (ip reverse) has been set to a DNS host record which is pointed to your server and matches the IP.

Also make sure as TGates jsut said you have SPF records setup

This still isn't absolute but will help
