This problem has reared its head in perl 5.14.2 on FreeBSD 8.3 in the execution of postgrey. Turning off taint checking makes the error go away.

Is the bug in perl itself or in the perl modules it calls? All have been rebuilt and reinstalled from source in the past few days to ensure nothing was damaged or out of date. FWIW, it doesn't happen if you choose the unix domain socket but then you can't daemonize the process on the command line: you can add an & but you can't use the -d argument. Details:

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
