MoneySavingExpert.com weekly email treated as spam

[#1]

I am really getting fed up with this new spam system. There is no way this should be treated as spam, previous weeks newsletters have come through OK.

Its happening to outgoing emails as well see http://community.plus.net/forum/index.php/topic,101583.0.html

The problem presumably relates to people who have subscribed to MoneySavingExpert.com and then decided they don't want the emails coming in - so have lazily just hit the Spam button rather than doing the proper thing and unsubscribing.
I have set the "Aggressiveness of the spam filter:" option to the minimum - and it seems to be about right at that level. Do others have higher settings?
