Hello

Just for your information.

Ian had answered privately to me with the details. According to 
it, this e-mail tries to trick the reader into clicking a link (if 
the image is not visible, which would be loaded from a remote URL) 
to probably verify the e-mail address of the receiver. Luckily the 
URLs are (probably wrongfully) pointing to click.freebsd.org which 
does not exists. The e-mail use a faked sender address which is 
set to freebsd-security at freebsd.org, but according to the header 
lines the e-mail was not sent from a system belonging to the 
FreeBSD project.

I have sent an e-mail with all the details to the admins of the 
mailing list, as I suspect we have a rouge subscriber in the list.


bye
Fabian
