Yes. Older version of Tobit Infocenter has failed CMDSPACE. I've send them some informations about the effectiveness of the CMDSPACE test and as I know they have changed their MTA in never releases. This happened around a year ago. Then there is also the good old pullmail.exe that will fail the CMDSPACE test CMDSPACE on my servers is able to catch around 30% of all processed messages as spam. (54% is hold as spam, 46% delivered as ham) Nevertheless there is around 1% of all messages classified as legit but with a positive CMDSPACE result. Looking at the subject line (I haven't the headers of this messages) it seems to me that from this 1% some are spam messages slipping trough the weighting system. Much more are automated messages like Newsletters, order confirmations, Webform-requests ond so on. But there are also some few subject lines beginning with "RE:" and "FWD:" looking very legit. As any user on my server must authenticate and auth-ed users are whitelisted it looks like there are some very few MTA's that will fail CMDSPACE. Anyone knows what MTA is used at nestle.com?
