SpamAssassin is a free utility offered to all InMotion Hosting customers to help combat spam. SpamAssassin works by blocking unwanted email addresses before they reach your email's inbox. By default, SpamAssassin is disabled so you must enable it within cPanel to take advantage of it's features.

How does SpamAssassin Work?

SpamAssassin is not an email filter, as some other spam preventin tools are. Instead, it determines whether an email is spam as soon as it hits the server. SpamAssassin works on the back end of your email server and has 10 different levels of settings to catch spam. When enabled by default, you will be set to 5. This is mid-range.

What does this default score of 5 actually mean?

How the point system works

SpamAssassin uses a points based system called "hits" to label spam. When it finds particular characteristics in an email it assigns a point value. If the email exceeds the maximum point value you set, the email is flagged as spam.

The lower the score you set, the more email will be caught as spam. For example, a setting of 1 means that only one hit needs to be flagged against an email for it to be considered spam. If you set the score higher, more hits will be required on an email for it to be labeled as spam. So, the lower the score, the more emails should be flagged as spam.

We suggest testing the different settings prior to using a higher setting.

Enabling SpamAssassin

The first step to enabling SpamAssassin is to log into cPanel. Once logged into cPanel, look for the icon called "SpamAssassin" under the Mail section.

Since SpamAssassin is disabled by default you will need to enable it. To do so, click on the "Enable Spam Assassin" link.

Now that you have enabled SpamAssassin, you will see a confirmation page. Congratulations! You are finshed! Click go back if you wish to modify the settings for SpamAssassin.

Using Filters to Organize Spam

In order to maximize the true power of SpamAssassin, we recommend you set up a Filter/Message rule in your mail client. Emails that are determined to be spam are still delivered to your inbox. Spam will begin with the subject line "***SPAM***". By setting up filters in your email client you can sort the mail and have all messages labeled as spam placed into its folder for review later.  This will keep junk mail out of your inbox. To learn how to set up filters in various email clients, please visit our guide on setting up email filters.

When I identify SPAM emails, do I place the word SPAM on the subject line?

When SpamAssassin identifies any spam, it will automatically place the word spam within the subject line.

I've never ONCE seen a spam e-mail come through my SpamAssassin filter with "spam" appended to the subject line.  I've got my Spam Score set to 1.1, and I specifically added rules to my configuration file that call for the subject to be modified.

Hello Craig,

Thanks for the comment. If you want to see if you're getting any spam, log in to webmail then look for the SPAM folder and see if spam is being stored in the folder. Otherwise, you may not be receiving any spam into your account.

Arnel C.

It seems the instruction on this page counter the instructions on Spam Assasin...they say set the number higher (for ISP) " but if you're an ISP installing SpamAssassin, you should probably set the default to be more conservative, like 8.0 or 10.0"

Hello Michael,

Thank you for your comment. SpamAssassin uses a default threshold of 5, as per their Official Documentation.

You can always change your SpamAssassin settings in cPanel at any time.

If you are following a specific guide, we would be happy to take a look? Can you provide a link to the guide?

If you have any further questions, feel free to post them below.
Thank you,

-John-Paul

On shared hosting accounts, it is not possible to filter zip files, however, on a VPS or dedicated server, ClamAV can be set up which will scan and remove unwanted zip files.
