[dkim-ops] Compatibility problems with perl Mail::DKIM

I hacked up a mail signer using the Mail::DKIM module from CPAN.  It 
happily verifies its own signatures, but when I send mail to the various 
test reflectors, they tell me that the body hash is OK but the signature 
is bad. Before I start picking bits, is this a known problem?

The module's SSP is totally wrong, written to an ancient draft, but in a casual 
look at the signing code it looks like it's supposed to be do 4871.  My 
sigs use sha256 and simple canonicalization.

R's,
John
