I have a separate 'white' filter for that sort of thing :)

I don't know how hard it would be, but what about just adding in a "pre" filter in the spamdomains test that will bypass the test. Like:
Spamdomains.txt:
[RDNS excluded from check]
ebay.com greetingcardvendor.com
[includes] .yahoo.com @msn.com etc, etc
This would also allow us to build our list of acceptable excluded addresses together, further improving the tests accuracy.

Alejandro,
From the Declude JunkMail manual page:
"This test will catch E-mail that is not coming from a mailserver that it should be coming from. This test will only work if you set up a file listing domains that you wish to be included in this test. Specifically, it will check the return address of the E-mail, and then check to see if the reverse DNS entry of the IP that the E-mail was sent from contains the domain name. If not, the E-mail fails the test. For example, if "hotmail.com" is listed in the \IMail\Declude\spamdomains.txt file, then an E-mail coming from "law2.hotmail.com" would not fail the test, but an E-mail from "mail.example.ru" would fail the test."
You can search the archives for some discussions of this. It's hardly foolproof, things like greeting cards and send-a-link sites will often fail the test because they send E-mail with a MAILFROM address of the person sending the note and not the service sending the note. I suggest that you always use the @ symbol in the first column, and you should set up two different files and score them differently. One should be for ISP's and E-mail providers such as AOL, HotMail, Yahoo, etc., and the other should be for businesses that are often spoofed such as Microsoft, PayPal, Symantec/Norton, McAfee. Be careful not to include companies that may use thrid-party mass mailers for newsletters. The second type of test can be scored higher because you are less likely to be getting greeting cards from people with real addresses at these companies than you are from places like AOL.
You might also be thinking of including your own domains in this test, but that again should be in a totally different file, and scored very low because even if you are using WHITELIST AUTH functionality, you will most definitely get users sending E-mail with your hosted addresses configured in their E-mail program but are using someone else's mail server, or without WHITELIST AUTH, they will fail when using your own mail server.
