Setting up a .forward file
From ProgSoc Wiki
If you want to forward email from your ProgSoc account to another address, the process isn't too difficult.
First you will have to log in to your account. You should have been provided with a username and password into ProgSoc's systems.
Once you are in your home directory, type in
cat > .forward
then hit [enter] or [return]. The cursor will move to the next line.
Next, type in the email address you want the mail to be directed to. Hit [enter] again, then [Control] + [D].
If you now type in
the email address you entered should be displayed, and any email sent to [your username]@progsoc.org should be forwarded to the designated address.
