I am wanting to use a 2048bit DKIM key. Following the instructions at http://support.simpledns.com/kb/a62/configuring-dns-records-for-domainkeys-dkim.aspx I have created the entry.
However, when the key is requested it is being truncated resulting in the DKIM check failing.
By testing it appears that Simple DNS plus 5.2 can only return keys with a maximum length of 1024b.
How can I get a 2048b key to work?
