Partial word filtering

Does the filtering in DA allow for partial words/phrases?
It seems like some of the phrases I have in my "blocked words" list are still getting through. How does it determine what a word is? Or does it just match the phrase anywhere in the email to be blocked? Does it search html tags in the email too?

Hello,

I believe that exim defaults to only checking the first 500 characters. So if there is text after that, it won't be checked by the filter. You can add:

message_body_visible = 3500

to the exim's main config settings in the /etc/exim.conf to enable more characters to be checked (note that this will use more resources)

Filters will find partial words, so for example if you set it to filter "oba", and the word "foobar" comes through, it should be caught by the filter.
