Found the mail header modification that cause DKIM verification problem in
my case from mails coming from gmail.com (and other) to my courier
servers.

It's "Content-Type" header. Its value is not case protected by the DKIM
relaxed alghoritm specification at sign level, even if CT value should be
trated as case insensitive.

For those interested, please follow the thread at OpenDKIM Users mailing
list: http://lists.opendkim.org/archive/opendkim/users/2010/04/0213.html

Ciao, Dino
