Is there a quicker way to address e-mail for users on-campus?
Yes. If you are sending e-mail from the NetMail web client to an on-campus address, you can enter the username by itself.
Example: doej instead of doej@uwplatt.edu
Most desktop e-mail clients support a similar feature. If you enter uwplatt.edu as the default domain setting, then the client will automatically attach @uwplatt.edu to the addresses you specify.
