Hi,

Often junk mail is selected due to improper domain name configuration and/or public IP configuration.

Is your mail server setup with a public IP address ?
Can you post the SMTP header of the rejected/junk mail ?

There is no reverse DNS lookup entry for your domain name. By default, most mail servers will automatically classify email from your server as spam or simply refuse to talk with your server. You will need to have your ISP add a reverse DNS lookup for your IP address (assuming they're willing to do that).

nslookup 218.81.109.81
Server: 192.168.50.1
Address: 192.168.50.1#53

** server can't find 81.109.81.218.in-addr.arpa: SERVFAIL

218.81.109.81 is currently listed in dynablock.njabl.org as a dynamically assigned IP address. Some mail servers are configured to reject mail from hosts listed in dynablock.njabl.org. Some mail servers are configured to tag mail from hosts listed in dynablock.njabl.org as spam.

If you have a static IP address from your provider, ask them to set up reverse DNS for your IP address and then ask njabl.org to delist you from dynablock. Note the following requirement for delisting:

Quote:

If you claim your IP space is not dynamic, it will have to meet one of two conditions for removal to be considered:

* Your IP space must be reassigned via whois to show that it's "your address space".
* There must be unique (non-script-generated) rDNS for your IPs. rDNS for 1.2.3.4 of 1-2-3-4-blah.some.provider or blah-10-24-3-4.blah.some.provider do not qualify.
