How Does Postlayer Work?
Postlayer is the spam filtering service that CourseVector makes available to clients at a small fee. It has historically be 99% effective.
First, we do not filter or block any email, other than viruses. Legally, it is questionable to block emails, spam or not, from an individual’s email box. Instead, the correct way to handle spam is to have it “flagged” and then filter it to a folder using your email client. That is exactly what Postlayer does. Following is how you can tell why an email has been “flagged.”
Postlayer will write a code in the subject of the email if it detects certain types of spam. You can then use your email client, based on that code, to filter the email to your junk mailbox.
[ConfirmedSpam] – This code indicates that the email is positively spam. It is safe to filter or delete messages with this code in the title.
[LikelySpam] – This code indicates that the email “could” be spam. It is highly likely that it is spam, however, we would suggest filtering these to your junk folder rather than deleting them.
[ConfirmedPhishing] – This code indicates that the email positively contains a phishing scam. It is safe to filter or delete messages with this code in the title.
[LikelyPhishing] – – This code indicates that the email is most likely a phishing scam. This code has a high degree of certainty, but we still suggest filtering the messages to your junk folder rather than deleting them.
[WordList] – This code indicates that we, at CourseVector, have utilized the training function of Postlayer and fine tuned or added some spam filters of our own. These are highly accurate, however, once again, we would suggest filtering them to your junk box rather than deleting them.
If you use Outlook for your email client, rules are used to filter mail to folders. Information on how to use outlook rules is available here. Almost all webmail and desktop clients have rule/filtering capabilities. If you need help, Google your email client and there should be information available. Or, you can always contact our support and we will be happy to point you in the right direction.
