Last Sunday morning I changed to Mollom from Captcha to stop spam from our webforms. Spam had slowly grown and we seemed to get a few each day. I installed Mollom (free account) and the module told me that all was OK. However, by morning of Wednesday, we had received NO inquiries from the website whatsoever, and also no spam. Since we have at least 2-6 inquiries each day, I was alarmed and thought it must be the Mollom set-up preventing emails. I checked the submissions for each form (3) and there were no submissions after 27 Oct. I then disabled Mollom and re-enabled Captcha set to the Math problem. We are now getting the spam again, but only one (1) legitimate email and it's now Friday morning. Is it possible that something has "infected/taken over" and is preventing legitimate webform submissions? I have tested the system (not logged in but as a visitor) and my test emails are going through. Any ideas?
