Hello Greg Troxel,
Am 2010-12-12 10:51:50, hacktest Du folgendes herunter:
Trying to block this is a bit tricky, because when a user of one of
these sites invites a specific person by entering an email address, it
isn't really spam. The problem appears to be that the sites offer the
ability to upload one's entire email contact list and then clueless
users somehow click on the 'spam my entire addressbook' button.
Sometimes my mailinglists are hit in a very short time by 10 to 20
invitations and multiply each be the factor 3-4000 which is not funny
if you have only a 100 Mbit internet connection.
A possible approach in SA is to have=20
=20
rules that matches each invitation type
a metarule for INVITATION
=20
rules that match mailinglist messages (eg List-Id: for mailman)
a metarule for mailinglists
=20
a metarule for invitation over a mailinglist, which IMHO is
intrinsically spam and could well just get 5 points
1+
I vote for a SA rule concerning MAILINGLISTS+INVITATION
And I hate INVITE messages which use the Original Senders E-Mail because
if they would use the own domain I could block it on SMTP Level.
Hi Michelle,
if everybody were using strict DKIM or SPF, these invites would go away :)
So how about trashing everything that says invite and LIKELY does not come from
the sender's
domain?
as far as I know, linkedin mail comes from linkedin domains, and has
valid DKIM sigs.
the sample posted by Michelle came to her via a debian list. debian
lists are open (no subscription required) and thus attract a lot of spam.
