I have been using GMail as a Spam Filter for quite some time. However, in the recent past I have experienced some weirdness and was wondering if something changed on my end, I did something different/wrong or if something changed on GMail that I was not aware of.
In my mail scenario, all of my mail gets forwarded to my GMail account from all my other email accounts and I use the GMail POP feature to download/archive my mail on the server. In the past email that was stored in my GMail spam folder was never downloaded via POP to my local email client. However, for the past few weeks that seems to have changed. I have started to receive Spam that has been marked in GMail in my POP client as well.
What am I missing? Are you seeing the same thing?
[EDIT] It turns out that I WAS missing something (this also might help someone else). Apparently, if you redirect an email address from inside Plesk, Plesk assumes that in addition to redirecting the email, you also want to archive another copy on your local server. My email client was setup to download from both places and so I saw copies of the spam messages as well.
