No option for DKIM selector

[awirthy]

I'm looking into enabling DKIM on my PMG and am wondering what I am supposed to add to the Selector windows when creating the selector. As currently the selector list is blank (see image).

Can someone please point me in the right direction?

You should be able to just type a value in there (say, key1) to create a new key. The drop-down is to allow you to select an existing key to use (or replace), if any.

what is the importance of the selector text? can it be any text?

The selector is used to link your private key with your domain in DNS:
<selector>._domainkey.<yourdomain>.<yourTLD>
it is also present in a DKIM-signature header.
with this the DKIM checking software can take the selector from the header and construct the DNS-query to get the public key for verification

I hope this helps!

Thank you. I've now got this setup.
