I have newest ISP under Ubuntu 16.04 LTS - Perfect Server setup. In last week I have set DKIM for few my domains. Today I checked the result using MxToolbox and I see message that "Public key has been revoked". Could you tell me why this happens? I have generated DKIM under Email --> Email domain --> DKIM button --> Generate DKIM Private-key. I did not change anything except enabled DKIM by using "enable DKIM" checkbox. PS For each domain I did this same, so each of them has this same selector name - default.
If you're not managing by yourself your DNS records then: 1 - open your ISPconfig 2 -go to EMAIL section, choose your domain 3 - click "DomainKeys Identified Mail (DKIM)" botton and copy your DKIM key. 4 - go to your DNS registrant and change DKIM to legit
Thank you but your answer is not related with my problem. You almost described the way of DKIM generation but I know how to do it. Fortunately I have found the core of my problem. Newest version of ISP generate 4096bits DKIM key but MxToolBox supports only 1024/2048bits. I tried another dkim tester and all work properly. Btw - as I wrote earlier - I have own server with ISP, so I probably manage my DNS.
many people - many ways. I have own server with ISP also but i'm not managing my DNS by myself Anyway, congrats you solved your problem
