The IRS had a contract with email backup service vendor Sonasoft starting in 2005, according to FedSpending.org, which lists the contract as being for "automatic data processing services." Sonasoft's motto is "email archiving done right," and the company lists the IRS as a customer.
In 2009, Sonasoft even sent out a Tweet advertising its work for the IRS.

UPDATE: I think I have found out why our representatives in DC are so clueless. I tried using the contact page at Darrel Issa's website but was blocked because I am in his district. I then tried faxing a hard copy of this article to his DC office using the FAX number from his website ... four times! All four failed, the first because his FAX doesn't support color and the final three with a communications error. If any of Rivero's Rangers has a contact on Issa's committee, get this article to them now!
UPDATE 2: I tried FAXing to Darrell Issa's district office. That connection also failed.
