Earthlink MX from *Earthlink* dynamic IPs blocked?

[jra at baylink.com (Jay Ashworth)]

I'm trying to get my sister's MythTV DVR to send her a daily email with its
recording schedule.  Earthlink is apparently blocking the email because it's
coming from a dynamic address -- even though that address *is an Earthlink
cablemodem*.

Is there anyone from Earthlink email ops around who can confirm that's 
actually the proper interpretation of your policy?

Cheers,
