I have one solution for the ecards... This little regexp (in pcre
format) should block it without blocking any legitimate email. I have
this in header_checks in postfix.

if /^From: +"postcards\.org"/
!/<[^>]+postcards\.org>/        REJECT Forged ecards (postcards.org) spam!
endif

Because all that emails had From in the form of:
"postcards.org" <some_forged_email_from_different_domain>
So we match the first part and then ensure the same domain name is not
used in the email address. It comes from several domains, but I don't
know how to put them in the same rule, so I have new rule for every
domain. Here is list of what I've got last week:

hallmark\\.com egreetings\\.com riversongs\\.com greeting-cards\\.com all-yours\\.net E-Cards\\.com postcards\\.org

Today I'm going to try the PDFInfo plugin to SA...
