in thread Is using 'Cookies' impractical for 'Contact Us' forms?
On the NMS support list we actually do see quite a few people reporting "spamming attacks" on both FormMail and TFmail installations used as "Contact Forms". Often these appear to be simply probes to determine whether the program can be exploited to send spam to a third party but we also have seen an increase in people getting stuff that looks like the "spammer" was actually targetting something like phpBB with comment spam; this is probably some robot indiscriminately submitting the data to any likely looking web application.
In the relatively low volumes that people tend to get this could be shrugged of as a mere irritation, but it could get to be a serious nuisance if one had a large number of forms.
