Hey guys,

Weird problem... Can send email from the server, but cannot recieve email to the server. Checked Exim logs and here is some data I've been getting...

Code: 
2009-12-07 10:39:48 1NHfgi-0003a1-OL <= <> R=1NHfgi-0003Zy-Ig U=mail P=local S=1433 T="Mail delivery failed: returning message to sender" from <> for [email protected]
2009-12-07 10:39:48 1NHfgi-0003a1-OL User 0 set for local_delivery transport is on the never_users list
2009-12-07 10:39:48 1NHfgi-0003a1-OL == [email protected] R=localuser T=local_delivery defer (-29): User 0 set for local_delivery transport is on the never_users list
2009-12-07 10:39:48 1NHfgi-0003a1-OL ** [email protected]: retry timeout exceeded
2009-12-07 10:39:48 1NHfgi-0003a1-OL [email protected]: error ignored
2009-12-07 10:39:49 1NHfgi-0003Zy-Ig Completed
2009-12-07 10:39:49 1NHfgi-0003a1-OL Completed

and...

Code: 
2009-12-07 10:38:21 1NHccL-000207-K3 == [email protected] <[email protected]> R=lookuphost T=remote_smtp defer (-46): SMTP error from remote mail server after end of data: host mailin-04.mx.aol.com [64.12.138.88]: 421-:  (DNS:NR)  http://postmaster.info.aol.com/errors/421dnsnr.html\n421 SERVICE NOT AVAILABLE
2009-12-07 10:38:21 1NH9ba-0004Zf-KY SMTP error from remote mail server after end of data: host mailin-01.mx.aol.com [64.12.137.169]: 421-:  (DYN:T1)  http://postmaster.info.aol.com/errors/421dynt1.html\n421 SERVICE NOT AVAILABLE

Any ideas?
 
Redirects the root@ email to your personal email address. Then you wont get that first error.
 
Nice - i'll have to keep that command in mind, very handy... Thanks! Any ideas on the rest of my incoming email? This server is not production yet, although I do have one client on it for testing purposes and the now have no email (and we don't corporately either). Any help or leads are appreciated.

FYI: My firewall is fairly restrictive - could that be an issue?

This error means it thinks your ip address is a dynamic ip and not a static ip. Ensure that it has reverse dns ptr setup on it so your ip reverses to the hostname it is sending email from. This would be the hostname of that server more then likely. If you do not know how to setup dns ptr records you need to ask your isp to set them up for you.

I have PTR records, but this is a good lead - would this prevent all of my email on the entire server from being received? I will make sure they are pointing where they are supposed to. Any other leads would be great
 
Notwithstanding what intodns.com is telling you, when I do some lookups I see that ptihosting.com has an mx record pointing to mx.ptihosting.com, and mx.ptihosting.com has neither forward nor rDNS.

OK - I should know better than to ask DNS questions here, but is there any way for me to check the DNS records from DirectAdmin? I also have Webmin installed on this box for these types of purposes, but I'm not sure exactly what the conditions are for adding rDNS (I know how to do it, but Webmin doesnt seem to let me)... And I still do not see ANY mx record pointing to mx.ptihosting.com...

Where is a good suggestion to start tracking this down? My client can still send a good majority of his email, but there are some domains he cannot send to without a return error (AOL is one of them).

Any help here is appreciated.

intodns.com is a good place to start. But you need to make sure that the domain's DNS is in fact being served at your server; check the nameserver information at your registrar to make sure it's pointing to your box. Once you know that's happening, make sure the DNS hosted on your server is correct.

Generally your upstream will host your rDNS for you, and not allow you to do it yourself; check with their support staff.
