Email warning

I love lawyers.

When I signed up for Safeway’s online shopping service I received an automated email confirming my signup. Attached to the bottom of the message was the following note (emphasis added):

Warning: All e-mail sent to this address will be received by the Safeway corporate e-mail system, and is subject to archival and review by someone other than the recipient. This e-mail may contain information proprietary to Safeway and is intended only for the use of the intended recipient(s). If the reader of this message is not the intended recipient(s), you are notified that you have received this message in error and that any review, dissemination, distribution or copying of this message is strictly prohibited. If you have received this message in error, please notify the sender immediately.

So if the message was sent to me in error, I am prohibited from reading it. Obviously if I have read the warning, I’ve read the message. And I can’t make copies? I use an IMAP mail server, so there are at least two copies automatically. One on my server and one in my mail client.
