I'm having external ip and ubuntu server with exim4.71 and bind9. I'm trying to set valid dkim entry to send mail for gmail

Here are my configuration files: bind9:

_domainkey.example.com.       IN      TXT     "o=-;"
mail._domainkey.example.com.  IN      TXT     "v=DKIM1;k=rsa-sha256;p=MHwwDQYJKoZIhvcNAQEBBQADawAwaAJhAMDO8xXc3fMjQnWs6ejxTsrMa4xvb0470b2wCIbx1/790huhBr1386mkvvzeTpDDwkFmOZWXnJLw+Qeh4p/rkNQ7AVCk2uZQ+Kwy+jxM17QdZaDxSY9U1HYUFXC8BKAUYwIDAQAB"

    Solution: change dkim field in BIND9 zone: from v=DKIM1;k=rsa-sha256;p=... to --> v=DKIM1;k=rsa;p=.... rsa-sha256 or rsa-sha1 doesnt work for me :(
