'ask a question about this product' emails should have ip to block spammers

[carsten888]

Since updating to vm3 I get loads of spam via the 'ask a question about this product' form.

A question was asked by zlzjcs (htrtvq@qowsre.com)

Can the ip of the user be included in the email? So I can block the ip adresses.
