text: Title: Domain DKIM don't sign mail
  Body: Hello everyone,
  
  I don't think i'm the only one to have this issue.
  When I do all the configuration for domain and the DKIM box it's green, my mail don't pass dkim on gmail or other webmail, can someone help me to fix that please, i read some articles about openDKIM on mobodoa website or github but don't work for me, or I fail somewhere.
  
  Thanks in advance for your answer.
