It's not unknown.
With the increase in anti-malware protection, spammers are finding fewer
zombie PCs to use to spread their spam.  This has (fortunately) caused
them problems (not enough problems though) and they've started
targetting web-forms that look (to their search agents) like they should
send email.

As I understand it, it isn't enough to ensure that your web-pages with
forms on them are secured against misuse, but you also need to ensure
that the underlying CGI code validates all the data it read in, as the
spammers don't limit themselves to just the kinds of data your web-form
can submit - they'll drive your CGI code directly.

A trick I've seen is to require users to "register" on the site (and
thus provide an email address that is used to supply a password, thus
ensuring that the user does have a valid email address) and use that
email address as the "from" field on any emails a CGI script generates,
and ensure that your mail relay checks incoming emails for valid "from"
addresses.
Time-based obfuscated hidden fields that the CGI looks for is another
trick - I wouldn't expect spammers to spend too much time working out
how to fool your CGI.

I've no idea how one might apply these tactics to Magnolia based sites
tho' (I'm no expert on Magnolia), but I can tell you that this isn't
just a problem with Magnolia sites.
