Have you guys other than the ones on road runner contacted your ISP's?
Greg - here is what's shown in the log files for your email:
Mar 23 02:23:33 tdr sendmail[97768]: h2N2NSoh097768: to=rockinbranch. boardman@verizon.net, delay=00:00:05, mailer=esmtp, pri=30150, dsn=4. 4. 3, stat=queued
That tells me that your ISP accepted your mail. Yours is probably sitting in a SPAM catcher account of some kind. Ask them about it - others have done so and found all of their TDR mail sitting in there. We have no control over what your ISP does with your mail, all we can do is send it.
Here's yours Gene:
Mar 23 06:29:21 tdr sendmail[99726]: h2N6TB9q099726: to=gene@sledpuller.com, delay=00:00:10, mailer=esmtp, pri=30176, dsn=4. 4. 3, stat=queued
Looks like the same thing - your ISP is accepting it and it's in their system somewhere.
