How to add DKIM on namesilo?


Any idea how to add dkim on namesilo?

When I try to add the value as a txt record, I'm getting an error that my value is longer than 255 characters. My DKIM value is over 400 characters.

Anyone done it before?



  • Had a chat with the support, it seems it's not possible at the moment to add a DKIM with 2048 bits... only 1024 will work since it's less than 255

    You may close the thread if you want.

  • Cloudflare is free and should support 2048 bit keys.

  • Why is it that you are using a 400 character key? Have you considered the problems that can be caused by large keys (such as being ignored/blocked by verifiers?).

    2048 bit keys are the maximum you can put into one TXT record, if you insist on using larger keys, you will have to split the text into two records.

  • @Ishaq, the 2048 bits resulted in around 440 character key.. I had to re-generate the dkim using 1024 bit in order to fit it on namesilo txt records.

  • Update on this - NameSilo now supports large TXT records, so these work now
