Such policies indicate either an agency that is not concerned with preserving good audit chains or one that has an extremely penny-wise, pound-foolish approach to IT policy. At prevailing wages—and hard drive prices—it is a waste of money to force even your lowest-level employee to spend time painstakingly deleting or archiving e-mails. If IRS staffers don’t have anything better to do with their time, then the IRS needs fewer staffers, not stricter mailbox policies.
In the case of a government agency, however, it’s especially troubling. Records pertaining to agency decisions are supposed to be systematically archived forever. I’m not saying that the IRS’s e-mail retention policy is uniquely bad in the federal government, only that whatever the current practice is, the IRS did not preserve nearly as much as one would like in a representative, transparent democracy.
