Description

Assuming the domain is example.com:

  • Generate the new key.
    cd /var/lib/dkim/
    amavisd genrsa example.com.pem
    chmod 0644 example.com.pem
    
  • Add it to your amavisd.conf file. Search for "# Add dkim_key here.", and add it alongside the others, preferably in alphabetic order so you can find it faster.
    dkim_key("example.com", "dkim", "/var/lib/dkim/example.com.pem");
    
  • Add your new domain to @local_domains_maps in amavisd.conf. The line should now read something like this:
    @local_domains_maps = ( [".$mydomain", "firstdomain.com", "example.com"] );  # list of all local domains
    
  • Restart amavisd
    service amavisd restart
    
  • Test that the key was installed properly
    amavisd showkeys example.com
    
    • The output should be something like this:
      ; key#1, domain example.com, /var/lib/dkim/example.com.pem
      dkim._domainkey.example.com.   3600 TXT (
        "v=DKIM1; p=" 
        "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDEzgjyG2It0ZdQQTgGNj2jNDKe" 
        "fsa978sd98fsd9vds97v9fHIUSAFHY(#@*oiu7cs98a9" 
        "afljhljoU(*@#&($*#@U9ujw9fewur0932870932" 
        "jvAe33lH9tiVljog1QYSUDOEAaads")
      
  • Add exactly what was printed above to the zone file in you nameserver(s). You should also include SPF and ADSP. For example a BIND configuration would look like:
    example.com.    IN TXT    "v=spf1 +a +mx ~all" 
    dkim._domainkey.example.com.   3600 TXT (
      "v=DKIM1; p=" 
      "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDEzgjyG2It0ZdQQTgGNj2jNDKe" 
      "fsa978sd98fsd9vds97v9fHIUSAFHY(#@*oiu7cs98a9" 
      "afljhljoU(*@#&($*#@U9ujw9fewur0932870932" 
      "jvAe33lH9tiVljog1QYSUDOEAaads")
    _adsp._domainkey.example.com. IN    TXT    "dkim=all"
