ARCHIVED: In IU Webmail, why are some of my sent messages not reaching their recipients, especially those outside of Indiana University?

IU Webmail does not use aliases or nicknames; thus if you do not specify a domain (such as @yahoo.com), IU Webmail will use the default domain @indiana.edu. For email addresses outside of Indiana University, use the complete address (e.g., jsmith@yahoo.com). For instance, if you enter only jsmith, your email will go to jsmith@indiana.edu if such an address exists at IU. If not, you'll get a message saying your mail could not be delivered.

Alternatively, add your colleagues and friends to your IU Webmail address book. Then, when composing a message, click Address Book and select the person to whom you're writing. For more, see ARCHIVED: In my IU Webmail address book, how do I add or remove entries?
