Hi,
Regarding the spams coming via membership form reported earlier, I can see that there is no image verification in the General membership form.
hence the website is susceptible to being spammed by an automated system.
Instead of looking through the emails which we receive at the server end, its best to stop the automated scripts/systems at the form level.
We can use Captcha fool proofing system (Image verification method)
Here is the quick how to for cpatcha implementation.

Hope this information will be helpful in managing the spams, please do let me know if you need my help in this regard.
Thank you,
