Zitat von RW <rwmailli...@googlemail.com>:
Are there really resolvers that can't handle it? My understanding is that the relevant limit here is on the length of a string, 255 bytes. Yahoo have broken their DKIM TXT record into multiple short strings to keep within the limit.
There are still enough resolvers around which cannot handle 2048bit DKIM keys. Sad, but true.
For example the well known registrar Hetzner from Germany cannot handle more than 1024 bit on their DNS software - tried it myself.
