Hi,

I just noticed that mail-add-payment (called from message-send-message)
doesn't recognise asynchronously generated payments for addresses that
contain uppercase characters. Attached is a patch that makes the test
case-insensitive.

An alternative solution would be to supply the "-C" option to the
external hashcash program, but IMHO this would unnecessarily restrict
the user in his customisation needs (hashcash-extra-generate-parameters).

Thanks,
andreas
