This page covers a range of frequently asked questions about the SpamDetour spam filtering service. If you have any suggestions for questions that are not included here, please let us know by emailing us at firstname.lastname@example.org
How does SpamDetour work?
Spam Detour provides business email security by Using our extensive anti spam filters and sophisticated virus scanning algorithms to stop spam and viruses before they have a chance to enter your all important network.
Spam Detour is a wide spectrum filter that utilises many different techniques and services to classify spam, this allows SpamDetour to filter email with extremely high precision. The Bayesian learning features ensure that as spam continually evolves the filter can learn the new characteristics of spam and keep ahead of the spammers.
How Much Spam Do Most Businesses receive?
It is difficult to quantify the amount of spam most businesses receive, partly due to the different number of ways in which people define spam. It is estimated that about 80 to 95 percent of the total volume of email that you receive each day qualifies as spam.
I was expecting an important email that hasn't arrived, how do I check it hasn't been stopped by SpamDetour?
You will need to check your spam cache to see if the message is being held back by the server as spam. You can sort the messages in your spam cache by clicking on the header of the column you want to sort by, you can sort by score, received time, from address or subject.
If you find the message you are looking for in your spam cache, click on the subject of the message to view it. Then click on the “Confirm This Non-spam” icon at the top of the screen to free this message and deliver it to your inbox. Doing this will also add the senders address to your white list so that any email from this sender in future is not stopped by the filter.
Some spam is still getting into my inbox, can I stop these in future?
Yes you can. SpamDetour includes an “auto learning” feature that can be trained to recognise spam, so that it continually keeps up with changes made by spammers. To train the filter to recognise a spam it has missed, locate the message in you non spam cache and click on the subject of the email to view it. Then click on the “Report this spam” icon at the top of the screen. This will increase the chances of similar spam to this being caught by the filter in future, the more spam that is reported this way the more accurate the filter becomes.
What does the Cache Contents page tell me?
The Cache Contents page gives you an overview of all of the mail that has been cached by the SpamDetour server. The non spam cache contains all of the email that has been already delivered to your inbox, this email is cached for a period of 5 days to allow you to report any spam that didn’t get caught by the filter.
- The spam cache contains all of the messages that have been classified as spam, and have been prevented from being delivered to you. These messages are cached for 30 days and this allows you to rescue any legitimate email that may have been caught by the filter.
- The virus cache contains all of the messages that have been detected to contain viruses.
- The banned-file cache contains all of the messages that have dangerous attachments, like .exe or .com files.
- The bad header cache contains and messages that have invalid email headers, depending on your filtering settings this may always be empty. The default setting is to only label email with bad headers, not cache them.
How do I add an Email address to my white list?
To edit your white list simply click on the “W/B List” item on the menu, this will open the screen where you can add and remove addresses on your white list or blacklist. To add an address simply type in the email address into the text box, ensure that the “List to add to:” option is set to “White list” and click on the “Add to List” button.
Any addresses in your white list will bypass the filter without any chance of them being tagged as spam. When you rescue an item from the spam cache that is not spam, the senders address is automatically added to your white list as well.
Conversely, any address you add to your blacklist will be blocked at the server, so you will never receive any mail from people whose address is in your blacklist.
How do I change my Username or Password?
To change your username or password click on the “Settings” icon on the menu to enter the settings section for your SpamDetour account. In the settings page find the section titled “Login Credentials”.
To change your username enter your new user name in the “New Username” field. To change your password enter your new password in the “New Password” and “Confirm New Password” fields.
Then to save your changes click on the “Update Login Credentials” button just below these fields, this will update the server with your new credentials.

Email is cached on the SpamDetour server for the following time periods :-
- The contents of you non-spam cache are kept for 5 days
- The contents of your spam cache, virus cache, banned-file cache and bad header cache are kept for 30 days
After the time period outlined above the emails are purged from the server. You will receive a reminder email every sunday detailing how many emails you have cached on the server.
Is there any online help available?
Yes there is, you can view the online help by clicking on the Help icon on the menu. This provides a general overview of the SpamDetour administration website, as well as information about mail filtering settings you can customise.
