Milter-greylist

Hi Atilla,

DNS isn't the issue. Apparently nslookup (or my command) was the issue
there, since:

root@myhost:~# dig +short txt
selector1._domainkey.outbound.protection.outlook.com.
"v=DKIM1;k=rsa;p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAvWyktrIL8DO/+UGvMbv7cPd/Xogpbs7pgVw8y9ldO6AAMmg8+ijENl/c7Fb1MfKM7uG3LMwAr0dVVKyM+mbkoX2k5L7lsROQr0Z9gGSpu7xrnZOa58+/pIhd2Xk/DFPpa5+TKbWodbsSZPRN8z0RY5x59jdzSclXlEyN9mEZdmOiKTsOP6A7vQxfSya9jg5"
"N81dfNNvP7HnWejMMsKyIMrXptxOhIBuEYH67JDe98QgX14oHvGM2Uz53if/SW8MF09rYh9sp4ZsaWLIg6T343JzlbtrsGRGCDJ9JPpxRWZimtz+Up/BlKzT6sCCrBihb/Bi3pZiEBB4Ui/vruL5RCQIDAQAB;n=2048,1452627113,1468351913"

So with dig I do get the DKIM key. And my SPAMD milter also checks DKIM
and says "DKIM valid". The strange part is that with the same nslookup
sequence on for example gmail I don't get the same issue, but anyway,
apparently it isn't the reason for milter-greylist to complain. Which
means I still have no idea. Every other domain is working fine, but all
Microsoft domains get a "retry later" every single time they connect.

I'm running Ubuntu 18.04, sendmail, milter-greylist, clamav-milter and
spamasassin-milter.

Anyone have any ideas?
