Email from infotecnica.com.br

Hi all,

I just posted to -performance and I received the following email from
postmaster at infotecnica.com.br:
"The email message sent to pgsql-performance at postgresql.org requires
a confirmation to be delivered. Please, answer this email informing the
characters that you see in the image below."
followed by a captcha image.

I think we should inform the user to remove this sort of thing or
unsubscribe him from the list. It's quite annoying and disturbing for
our users.

The header is:
