How to autorefresh mutt to see new emails?

[Pétùr]

Hi,

One of the issue I have with offlineimap is (inactive) mutt doesn't show my new
emails. I have to move inside mutt to see the new emails offlineimap
downloaded. If I have mutt opened but don't interact with it, it will
never update the screen.

I am looking a way to autorefresh mutt's emails list every x seconds.

I have set these settings in my .muttrc:

set mail_check=5
set check_new="yes"

But they don't change a thing.

Any idea?
