At least valinux and sourceforge setup a connect and will do some
verification before they accept email. It could be that this behaviour is
getting copied on other systems as well. I usually get some probes from
them after a message from me is accepted via a mailinglist from
securityfocus.
But it could be a more malicous probe. (Not that I happen to like their
approach.)

Don't meddle in the affairs of sysadmins,
for they are subtle and quick to anger.
