I need to create a TXT record for DKIM support for a registered domain at DynDNS. Since the DKIM data entails the base64 encoded public key, the string is rather long. It is rejected as such during data entry. I tried the recommended workaround by using several variations of concatenated strings (none with any spaces between the string delimiters) but none of these overcame the data entry error.
How does one create a TXT record to support current DKIM standards? Perhaps, I missed reading some documentation or support guidance elsewhere - my apologies as a newbie on the subject matter.
