Evolution/thunderbird

Hi, up to the time I moved over to Suse from MDV, I'd been using Thunderbird as a mailer. I've use Evo in the past, but changed when they introduced junk/spam checking, If anyone remembers it took ages to down load mail while it was being checked. One nice feature in Thunderbird was the ability to auto delete messages that were older than a settable time limit. Is this feature available in Evo, as so far I haven't found it ? TIA Richard
