With the PayPal transitioning its service for European customers
from UK to Luxemburg, it is beginning to use new sending address,
which may not be in people's whitelist, so here is my update
to facilitate legitimate PayPal mail reaching its customers
(I'm including ebay entries for good measure):
whitelist_from_dkim [EMAIL PROTECTED] paypal.com
whitelist_from_dkim [EMAIL PROTECTED]
whitelist_from_dkim [EMAIL PROTECTED]
whitelist_from_dkim [EMAIL PROTECTED]
whitelist_from_dkim [EMAIL PROTECTED]
whitelist_from_dkim [EMAIL PROTECTED]
It seems their legitimate mail need a little help, because
Bayes sometimes confuses them with phishing, because DCC hits
on them, and because MIME_QP_LONG_LINE is firing.
Their DK signature verifies just fine with recent versions of
Mail::DKIM through a Mail::SpamAssassin::Plugin::DKIM plugin,
which needs to be enabled. Note that Plugin::DomainKeys is
not needed, the Plugin::DKIM can cope with both signature types
(with historic DomainKeys, and the DKIM (RFC 4871).
I'd welcome contributions/updates to the above list
of popular, genuine and well-intending sending domains
protecting their mail with DK or DKIM, perhaps eventually
evolving in some form of a reputation list.
For completeness, here are my current rules to add few score
points to yahoo and gmail mail which fails verification:
header __L_ML1 Precedence =~ m{\b(list|bulk)\b}i
header __L_ML2 exists:List-Id
header __L_ML3 exists:List-Post
