Are there security issues around White House personnel using RNC email accounts?

This is speculative at this point, but with the revelation that Karl Rove does 95% of his emailing off RNC and Bush campaign accounts and other White House personnel have used outside email, Laura Rozen wonders about the security implications.

I mean, are the RNC or Bush campaign servers rated to carry classified information? Has anyone at the White House ever sent classified info over RNC servers even by mistake? Do you think foreign intelligence operations might have tried to take a look at those RNC servers?

Obviously they've been using the RNC and other servers to try to keep information out of Congress' immediate discovery, but in their concern over self preservation did they ever risk national security?

Just unbacked speculation at this point, but interesting, no?

(Related: ABC's Blotter adds this little bit pointing to broad use of outside emails including in the Abramoff case.

But Waxman also pointed to e-mails his committee received last year in connection to convicted superlobbyist Jack Abramoff, which show White House aides sending and receiving work-related e-mails from domains like "georgewbush.com" and "rnchq.org".

E-mail conversations uncovered by Waxman's investigators suggest that some White House staff and outsiders believed such e-mail, which evaded official ".gov" systems, could be kept private.

"...[I]t is better not to put this stuff in writing in their e-mail system because it might actually limit what they can do to help us," one lobbyist wrote Abramoff, citing advice from a White House aide, "especially since there could be lawsuits, etc."

Another stone to turn over.
