How this is done depends on the mailer, e.g. on UNIX you have to make a .forward file. Be careful for mailing loops. If you go to the US and forward all your incoming mail to the US, then you should not forward your US mailbox back to here when you leave the US, because this would be a mailing loop. If you forward mail, usually it is possible to keep a copy at the primary mailbox. Contact Herman Van Uytven or your local mail administrator.
Students can also register a forwarding in the student database.
