You can reject the mail with postfix's mime_header_checks
feature. Something like this (obviously untested):
# main.cf
mime_header_checks = pcre:/etc/postfix/mime_header_checks
# /etc/postfix/mime_header_checks
/^Content-(Disposition|Type):\s+.*?(file)?name="?ecard\.zip(\?=)?"?\s*(;|$)/
REJECT bad attachment name
You might need to tweak the above expression to match what's
actually in the file, but this should be a good starting point.
