Postscript: I do notice that 67.91.139.138 reverses to
<ip67-91-139-138.z139-91-67.customer.algx.net.>. I've heard rumor
that some spam filters will consider suspicious any IP address with a
reverse DNS that "looks like that". You may want to contact the
hosting provider and have them change the PTR record for 67.91.139.138
to something more unique, like <mail.shirevalleydesign.com.>.
