Filter on postoffice.reston.mci.net

Okay, I give up. Apparently MCI has an SMTP filter either 
on the domain netins.net or on something in the 167.142.0.0/16 
network on postoffice.reston.mci.net. 

[167.142.225.4]$ telnet postoffice.reston.mci.net 25

250 postoffice.Reston.mci.net Hello kevin at worf.netins.net [167.142.225.4],

I've called the iNOC, they sent me to a 'systems group'. The systems
group listened carefully and wrote down the error code '550 Access
denied' before shuffling me off to the Reston office. There, I spoke
to a very nice sales person, who searched a list of voicemail boxes
she might forward me to. 

We pay MCI good money, and find ourselves unable to send mail to
trouble at mci.net or other MCI addresses. Now I'm stuck in the MCI
phone maze. If there was an incedent warrenting an SMTP filter, 
we'd certainly deal with it if notified. I know if that happened 
with one of our downstream customers, we'd actually contact them 
before throwing in filters.

Anyone know who takes care of postoffice.reston.mci.net ?
