Mail alias for NTHU student mailbox

To provide NTHU students straightforward email addresses, we developed the new function of mail alias for student email services (@oz, @m98-@m109). For example, if the user of the email account s970000@oz.nthu.edu.tw set the “myalias” as his/her mail alias, any emails sent to myalias@oz.nthu.edu.tw will forward to the mailbox s970000@oz.nthu.edu.tw. The student user can set the mail alias, according to his/her demand.


  1. If an inappropriate alias is found, the division of network system reserves the right to inform and request users to change the alias.
  2. Each account can apply for only one mail alias. Once chosen, we do not accept changes or deletions. Please choose your mail alias carefully.
  3. Your mail alias is not your email account. While entering email verification information for related services, such as FTP, POP3, IMAP, SMTPAUTH, Webmail, mail reporter, and so on, please use your email account to login, not your mail alias.
