Multiple DKIM per domain

I have one DKIM key that I use with Google Apps. Which under the DNS TXT Record is v=DKIM1;

Now I am adding a second DKIM authentication for PHP mail. With this second key, do I make it v=DKIM2;, or do I leave it as 1?

Solution

  • v=DKIM1 must remain '1' as it represents the DKIM version, not the order of records.
