Configuring SpamAssassin

[Gregory Opera]

My domain host – netregistry (Australia) – hosts my domain using cPanel… I can login as an with my domain admin credentials and access all of which cPanel offers, whilst logging with with user credentials (i.e. one of the e-mail addresses I have created) will give me access to whatever cPanel features I’ve enabled/installed (e.g. webmail and ownCloud).

One of the user accounts in particular gets a lot of spam and I would like minimise the impact of this by redirecting spam to the “Junk” folder in Roundcube (or the respective equivalent in Horde/SquirrelMail).

When I login to cPanel with domain admin credentials, it says that SpamAssassin is enabled, however I clearly continue to get spam in my inbox (otherwise I wouldn’t even be posting this), even whilst my webmail is open in my browser (this occurred as I was typing this).

How do I configure SpamAssassin for my entire domain (i.e. all of the e-mail addresses I have created), so that spam is automatically moved to Roundcube’s “Junk” folder and will this occur prior to my e-mail hitting my IMAP clients (e.g. Mozilla Thunderbird, K-9 Mail, etc…)?

My domain host currently uses cPanel 64.0.22. I have a choice between Horde Groupware 5.2.14, Roundcube (I can’t find the version number) and SqirrelMail (I can’t find the version number), though I prefer to use Roundcube.

Thanks!

Hello Gregory,

The following document provides information about how to filter Spam into a specific folder:

How to Create a Spam Email Filter - cPanel Knowledge Base - cPanel Documentation

You can create filters for these messages for all of your email accounts in cPanel's Global Email Filters interface (Home >> Email >> Global Email Filters), or for individual accounts in cPanel's Email Filters interface (Home >> Email >> Email Filters).

Let us know if this helps.

Thank you.

I've created a few (global) filters just now, so time will tell how well this works...

Do the filters I have created affect delivery to third-party e-mail clients (e.g. Mozilla Thunderbird)(i.e. so that the "spam" is moved to the "spam" folder prior to being received in Thunderbird)? Or will I need to maintain separate filters in the third-party e-mail clients I use?

The email client should reflect the folders if you have configured the client to use IMAP, but it's likely a good idea to verify it works as intended when first setting this up.

Thank you.

IMAP and its synchronization is a wonderful thing; ever since I discovered IMAP many, many years ago, I have never looked back...

But what I meant will the global filters sort the e-mail before it hits <insert mail client>, even if I do not have the webmail interface open. Or will those global filters only apply only if I have opened the webmail first?

Also as best I can tell, SpamAssassin doesn't seem to do anything; the global filters (I created) clearly work, but SpamAssassin doesn't seem to catch anything as spam when I'm using Roundcube.

Does SpamAssassin only work with a particular webmail interface (Horde/Roundcube/SquirrelMail)? Or is there something I have not configured?

UPDATE: I can now confirm that it's not just SpamAssassin which does not appear to be working - the global filters are apparently having no effect either, as domains (i.e. "@domain.com") I have already added to the global filter list are still being directed to my inbox!

And in case you were wondering why I just did not edit my reply above - the forums wouldn't let me (they thought it was spam)...

This suggests a potential issue with how Exim is filtering messages on this particular server. Could you report this issue to your web hosting provider so they can review /var/log/exim_mainlog to see what's happening to the affected messages?

Thank you.
