Why does this page only refers to Mercury/32?
Mercury/32 version 4.01a and Pegasus Mail version 4.2 share exactly the same code for Content Control. The pages you are reading right now are created from the help file in Mercury/32.
Can we share???? YES, let's do that!!!
Did you create a content control rule that traps much of your spam and which is not yet in the spambust.dat file, please share that rule with me so David Harris can decide to add it to the master spambust.dat file.
You can get my own additions to the spambust.dat file by sending me a message with the subject send_spamadd (doublclick to send).
For sure the reply will be triggered by your content control setup so make sure to either whitelist me or keep an eye out for the message in your junk folder.
What is the Content Control feature anyway??
Let's face it, the worst thing about e-mail is having to wade through dozens of unwanted messages offering unwanted products and services every day - this kind of unsolicited commercial e-mail (more commonly-known as "UCE", or "spam") has become the bane of our existence in the last couple of years. Unfortunately, while spam is obviously a social problem, not a technical one, legislators around the world have been extraordinarily lax, even incompetent in their attitude towards it. As a result, we're left with no real protection from spam, even though it wastes a huge part of the Internet's dwindling resources each day.
Mercury and Pegasus Mail both provide a fully-integrated approach to handling this type of unwanted mail, but takes the notion even further, by allowing you to define for yourself what constitutes "unacceptable content" in both the e-mail sent to your site, and the e-mail sent from your site.
Just an advise: Do NOT alter the default spambust.dat file. Instead create your own additional CC-Set and create a separate file to store your own rules in. When you leave the original file unchanged, you can take advantage of the regularly updated file without modifications.
Using Content control you can create sets of tests that Mercury applies to every message it processes: each set consists of three separate and optional tests
What tests can be performed
A blacklist check
A whitelist check
A rule set check:
For messages that are not caught by the blacklist or whitelist, you can create arbitrarily complex sets of rules to test the content of the message. These rules are like Mercury's general-purpose filtering rules, but are more specific to the particular task of content evaluation, allowing unlimited numbers of "and" operations to link conditions together.
What actions can be performed
Each content control set has an action, which is applied when a message is deemed to have unacceptable content, this action can be
You can have as many content control sets as you wish - Mercury will apply them in the order they appear in the list in the Content control configuration dialog: the first set that results in the message being quarantined, deleted, or otherwise removed from circulation will terminate content control processing for that message
Using the Content control dialog in Mercury and Pegasus Mail
To create a new content control definition, click the "Add" button, click here for detailed information on the various settings associated with a single control set.
To change the values for a single content control definition, select the definition in the list and click the "Edit" button.
To remove a content control definition, select it in the list and click the "Delete" button: Mercury will ask you if you want to delete the list and rule files associated with the definition as well as the definition itself - if you use the lists or rules in other definitions as well, you should not delete them.
To adjust the position of a content control definition in the list, select it and click the "Move up" or "Move down" button. The position of a definition in the list is important, because Mercury applies them in the order they appear, and stops applying definitions to a message when a definition results in the message being deleted or otherwise removed from circulation.
Where can you get the latest CC-file
The latest version of spambust.dat will be available from our web site later.
