Is there a way to configure SpamAssassin to show any custom rules that an e-mail matches in the incoming headers, as the built-in rules do?
For example, I have the following:
Content analysis details: (0.1 points, 4.1 required)
pts rule name description
-0.1 RCVD_IN_DNSWL_LOW RBL: Sender listed at http://www.dnswl.org/, low
trust
[209.85.220.68 listed in list.dnswl.org]
1.0 FREEMAIL_FROM Sender email is commonly abused enduser mail provider
(eellibrown[at]gmail.com)
-0.0 SPF_PASS SPF: sender matches SPF record
-1.1 RCVD_IN_MSPIKE_H2 RBL: Average reputation (+2)
[209.85.220.68 listed in wl.mailspike.net]
0.0 HTML_MESSAGE BODY: HTML included in message
-0.1 DKIM_VALID_AU Message has a valid DKIM or DK signature from author's
domain
0.5 DKIM_SIGNED Message has a DKIM or DK signature, not necessarily valid
-0.1 DKIM_VALID Message has at least one valid DKIM or DK signature
X-Spam-Flag: NO
All of those rules are pre-defined. I have some custom rules that should also match, which are defined in my local SpamAssassin config file. I am not sure if the custom rules are being applied, since I do not see them listed in the header with the pre-defined ones, and the score does not reflect my custom rules.
However, if I change the scoring of the pre-defined rules in my local configuration, the new scores are applied correctly. My server support tells me that they have enabled the local custom rules, but I am still seeing spam which in my opinion should be blocked, that as far as I can tell matches some of my rules.
Basically, a few of our company's e-mail address have somehow gotten on some e-mail lists and they receive hundreds of spam e-mails a day. This makes it difficult to find the non-spam messages, which are a handful a day. I have been trying to make custom rules to reduce the amount of spam, but if I can not be sure my rules are being applied, I don't know how to ensure that any new rules I make or modify will actually block anything.
I am open to suggestions of other methods of blocking the spam as well, other than just getting new e-mail addresses for everyone (although that would be nice).
