The issue appears to occur sporadically with certain domains. One such 
example is yourshirevillage.com, and it, like the others, lists "mx" in 
the SPF record, and then has a couple hundred MX records listed. I 
believe the issue is that a corrupted DNS result is being returned, and 
that's what's triggering the segfault. I haven't been able to figure it 
out completely yet.
