How to filter for "NOT jpg"

[Quicksilver]

How do I filter such that I get everything except entries with the string "jpg" ?

I tried the following but it doesn't work:

[^j][^p][^g]

What should I use?

Where would you put it, in the filter profile? If it's the filter profile then just add

"[.]jpg" to the subject "Reject" list.

Basically, you can't.

Here's how to do not "jpg":
[^j]|j[^p]|jp[^g]

The issue is, "1jpg" contains "1jp" which is not "jpg", and as such, the entire post will pass. So this is only usefull if you know the entire subject of the item you want rejected before hand.
