Description

For rspamd, when setting sign_local = true; in dkim_signing.conf, I expect that normal internal IP addresses are "local" by default. Looking at options.inc, however, you can see that a comma is missing between the last two IP blocks. So the intention is clearly there, but it does not work.

This PR adds the comma. Mails sent from an IP in 192.168.. are now signed on my system, which did not work before.
