spamd will not bind to ipv4 localhost when network is unconfigured

[David Niklas <do...@mail.com>]

Hello,
Sometimes I start my computer when the internet is not available and I've
found that smapd will not bind to 127.0.0.1.
I'm having it bind to localhost only.
It instead binds to localhost's ipv6 address.
I don't know why it *must* connect to router to acquire an ipv4
connection to localhost.
I suspect this is a bug.
Thanks, in advance.
Here's the unwrapped syslog output.
