Please quote your host_reject_recipients setting. I predict it is of the
form
host_reject_recipients = *.something : /the/file/of/ips
You should put the file first. (If this isn't the case, something odd is
happening.)

This will happen with that kind of setting. It needs a host name, so it
tries to look one up.
