For one thing, the odkim.internal_ip() function is not available to any
script other than the setup script. I can't remember why that's so, but
thats how it is in the current version. I can't think of a good reason to
leave it that way though. I'll add it to all of them for the next

I couldn't get this to segfault with a build of 2.10.3 just now, at least
not in test mode (i.e., "opendkim -n -x path-to-config"). When you try
that, do you still get the segmentation fault, or does it have to run and
receive a message for that to happen?

That returns the set of domains defined by the "Domain" line in your
configuration file, if you have one. If you're doing the more modern
KeyTable/SigningTable combination, then this set will always be empty or
not exist.
