[Bug 1203547] [NEW] Spam from non-subscriber sent to subscribers-only list

[Andreas Klöckner]

Public bug reported:

Hi there,

A list that I run [1] just picked up some spam [2,3,4] sent from an
address that is not subscribed. The list has generic_nonmember_action
set to Reject, and I just tried sending email to the list from a non-
subscribed address (which is rejected as expected). Now I'm wondering
how the spammer was able to get his messages onto the list. Any help in
troubleshooting this would be much appreciated. The offending email's
headers are below.

Thanks,
Andreas
