Hiding deleted items from Summary buffer

[Sébastien Vauban]

Hello,

After many unsuccessful attempts, I'm deciding to ask you the
question, ie. trying to help me to remove the deleted items from
the Summary buffer view.

I've tried setting everything I could possibly imagine (playing
with the expiry function, moving articles to a "Trash" group,
etc.) but I do know what I'm not doing correctly...

My goal is that if I'm deleting one mail, I do not see it again
the next time I come back to that summary buffer. What can I do
to achieve that?

Many thanks,
  Seb
