What I get from this is (at the time) DNS providers (usually) allow for up to 1024 bit keys but not 2048 bit. Now, my provider does let me use 2048 and confirmed DKIM signs. Of course, the post claims 1024 is perfectly safe, but if I have the option to use 2048 I'd like to.
Am I good to go, so long as my provider supports that big of a TXT record? Or could there still be issues?
