Due to University policy, access is restricted to only a few domains. We cannot send or receive e-mail directly to/from most internet domains.

Instead of using the @space.physics.uiowa.edu address, you should be using our official university e-mail address. See our contact list, click on a name, then use the address shown after "send e-mail to." Using this address will avoid the block and will be delivered, assuming the message passes university spam filters. Most of the official e-mail addresses are of the form first-last@uiowa.edu.
