I was fed/fet up with the spam filter capabilities of most mail clients, as well as the difficulty of setting up a remote spam filter that would connect to my IMAP boxes, so I finally ended up routing all my mail through a gmail account and back into a secret unfiltered email address.
And it’s working.
Until the secret email address becomes compromized, I’ll probably not get much, if any, spam in my boxes. And the best thing about it is that finally my spam filter is not clientside, meaining I can open my IMAP boxes remotely and not see all the spam that my primary client would’ve caught.
Next up is to find a way to have an IMAP spam filter that I could train remotely by moving messages manually into a False Positives and False Negatives folder. That’d be uber-cool.
