It is simple to set things up so that email sent to your account at the School (eg. firstname.lastname@example.org) is redirected to another account, such as your UDUS account (see section 1.10 on page about using UDUS). All you have to do is to type:
% mlalias -C
For example, if you want to redirect email from the CSE account email@example.com to the matching UDUS student account firstname.lastname@example.org you would type the following:
% mlalias -C pats777 -a email@example.com
This will set up a `mail alias' with the same name as your CSE login name. In order to receive email at your CSE address as well as redirect it, you should type the following instead:
% mlalias -C pats777 -a pats777 firstname.lastname@example.org
As always, see the manpage for more information.
