Incoming mail has 3 options to convince defNULLspam of its legitimacy:
1) The sender is familiar to defNULLspam. This process occurs during installation of filter, when it collects all addresses on your system YOU have ever sent mail to. It then places those on an “approved sender” roster.
2) In addition every new address you send mail to after installation will be white listed, as you most likely expect replies from its recipients.
3) Incoming mail which is to date unfamiliar to defNULLspam, is placed temporarily inside a spam folder, to which of course you have access.
Each time a piece of mail of unfamiliar origin is received an automated response will be sent out to its point of origin. This automated response contains a code of verification.
The process of verification is quick and simple: all the recipient of the automated response will need to do is return it, unchanged. Returning this code/key will create a link to this address of origin and now placed inside the “approved sender list”. From here on out every piece of mail received from this sender will automatically be let through.
FAQ
How much does defNULLspam cost?
It is freeware and was created due to the author’s never ending disgust and frustration with his old anti-spam program’s inadequacy.
Does defNULLspam receive any spyware?
Absolutely not !
Does defNULLspam work with or in combination with other anti-spam programs?
Yes, but is not recommended. Many anti-spam programs, for example “Spaminhilator”, engage/employ a type of proxy setting. This means that incoming mail will be sorted before it ever reaches the actual (your) mail client. For defNULLspam’s user this by no means changes the programs ability to filter mail flawlessly (100%). However, it creates ambivalences for you, the user, as you have no way of being certain that the other anti-spam filter won’t by mistake drop an approved sender into its junk mail folder..
Doesn’t defNULLSpam’s automated request for address verification actually verify my address to the spammer?
NO! This belief has sadly enough and without any grounds to stand on snowballed into, what is known as an “urban legend”, which makes for hard times to convince people otherwise. Spammers fly with fake e-mail addresses for the most part. This means that any and all feedbacks to these addresses are of no consequence to a spammer, as they do not actually reach the spammer’s personal inbox. Even if a spammer’s address is legitimate it has no effect nor is it of any interest to the spammer whether the mailing list they operate from consists of legitimate addresses in order to inundate your inbox with more advertising and other junk mail. A spammer works without mail server resource limitations, meaning it matters not to the spammer if a million or 10 million e-mails must be sent out in order to receive back 100.000 responses from real/live users.
Will the new technique of using images in order to spam you be caught by defNULLSpam?
YES! There is a new trend spammers have embraced, in order to keep on advertising and thus falling through the proverbial spam filter cracks. They are using images, for the simple reason that the average, run of the mill spam filter cannot detect and therefore deal with this new way of spamming. In other words for you this means more junk mail in your inbox. defNULLspam not being in the least bit interested in the content of your e-mails you receive, solely concerned with the sender’s address is therefore not at all affected by the new spamming strategy. Once again no fooling defNULspam meaning for you the user that legitimate mail gets dropped where it belongs, namely your inbox and the junk mail in a temporary spam folder.
