DKIM Setup with external DNS Service provider

Jason Mills

Hi,

I am trying to setup DKIM.  I goto the protal and create the key etc and it gives me the name and key, i pop these into a txt record in my DNS and sometime later nothing happens.

the name is quite long               sophos757e65a5f75148e1aa230e0f1070951c._domainkey       and it automatically gives out a 2048  length key.  In my DNS txt record i have tried it complete and by breaking teh key in two with " " in the middle see if it is a 255 character issue but still with no luck.  

If i go onto my SEA appliance I can add a dkim record, text name smtp._domainkey with a1024 bit length key and it works no problem.  It just won't use the cloud generated one.

I cant use the one on the sea appliance and still route out through the sophos cloud gateway as it pulls it apart before sending on so I a get a dkim fail for that.

Does anyone have any hints?
