Oh, absolutely, it is a little rural ISP. http://www.mcn.org/Table/about/ MCN is owned by the Mendocino County school district ... Although I think now they have co-located their servers at Sonic or someone like that. Part of the reason, IIRC, is that their building is not real rain-tight, and it rains a lot here in the Emerald Triangle.

Another possibility ... I like this one ... is that your mail server is s-l-o-w to respond to a reverse DNS query. If so, maybe UA times out waiting for uribl.com to reply, and sends it again to uribl.com, which then bounces the request as 'too often'.
