As per Matthew Romanek's ([EMAIL PROTECTED]) recommendations, I re-pointed my resolver to a different nameserver (from resolving locally), and can successfully scan a message in a little under 2.5 seconds (2.3 - 2.4 seconds).
I already upgraded to perl 5.8.5 and Net::DNS 0.48, which didn't resolve the problem. Does anyone have any idea why it fails when attempting to resolve off the local nameserver? The resolver works perfectly otherwise. Any input appreciated. Thanks, .jon __________________________________________________________________________ "The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential, proprietary, and/or privileged material.
