Are you using anti-spam software?: Many people are using "anti-spam" programs, or subscribing to anti-spam services in an attempt to reduce the amount of spam they receive. Several of these anti-spam services prevent e-mail from being delivered to users until the sender of an e-mail goes through a lengthy authentication process. This process usually requires the sender to visit another web site where they must enter some identification in order to be allowed to send e-mail to the person in question. USUA receives hundreds of e-mails each day. Staff does not have time to go through these additional steps. Therefore, if you want to receive e-mail from USUA, it is your responsibility to make sure your anti-spam measures will accept e-mail from USUA. You should configure your e-mail client to accept any e-mail from the domain usua.org.
