hello bind network probleme with dk dkim and dlv for miltiple domain

[fakessh]

hello all reader
hello bind network

I am having problems with my dk and dkim signature of my emails
I have successfully made the process of verification of signatures dnssec
all my domains are correct and good displays on dlv.isc.org
the reason for my problem just the reason that I have updated my postfix
and I have recreated a pair of keys with openssl for dkimproxy

the reason for my questions
one of my domains. in .fr: before validation of signatures by isc dk dkim
said OK
Other areas domains ( other .fr and other .eu ) before validation of
signatures by isc dk dkim said bad


that happens I do not understand


thanks for advice
thanks for help
