Hi all,

I asked some time ago if it was possible to avoid having such big spam reports. This is a link to my previous post:

Thread 'Sam's, FedEx, C0STC0, Marriot etc'

Hi All,

we are getting Daily Spam Reports of 1MB in size approx.

There is a lot other spam with beg brands in them ... any tips on how to raise the Spam score so they get out of the report and are discarded easily ?

P.S.: I am using PMG 8.2.10

We get all sorts of spam pretending to be from big brands: C0STC0, Marriot, Lowes, etc.

A few tests on some strings being present in subject or sender could raise the spam level enough to avoid them in the quarantine report.

Any ideas on how to do this? Is there a sample rule I could tailor?

If you want the ability to reject mail based on spam score, I believe you must enable 'before queue filtering'. As far as custom rules, there are quite a few examples on here. You define those in /etc/mail/spamassassin/custom.cf. You can also define matches on headers directly in the web GUI and use these with actions in the Mail Filter section of the UI (these do not require before queue filtering in order to reject AIUI).

I wrote very lot about custom filter and how to define them in this thread.

[TUTORIAL] Thread 'Installation Advisory'

I've been intensively working with Proxmox MG over the past few days and found the documentation not always helpful.
My spam has been reduced by 95%, and I would like to explain here what I changed compared to the out-of-the-box installation to achieve this. From my perspective, this is something that is insufficiently covered in many guides.
Thanks to the Proxmox team for this excellent product and thanks to everyone whose comments and recommendations I implemented. Feel free to comment — if you like this post, leave a subscription and a like … just kidding.
