I am using smartermail built 7957 (Oct.2021). I know, did not upgrade yet as I am on a 2012R server...
In any case, I set up DKMI signing. For smartermail all looks good.
I set up the record in my DNS provider (DNSMadeEasy) and...
I had a lot of reports for DKIM record missing!!!
If I use MXtoolBox and the DKIM lookup... indeed it says:
test: DKIM Record Published
resukt: No DKIM Record found
Now, I have multiple domains for the same IP address. So I added one key in the DNS for everydomain... Everykey is supplied by smartermail. The key is there, smartermail detects it... (it was generated by smartermail), but everybody else seems not able to see it. Any advice? This happens for all domains!!!
