I am using an IMAP email account. I created a filter in Evolution to move email from a specific high-volume source into a particular folder, to keep the Inbox uncluttered. I noticed that incoming emails are coming straight into the Inbox. If I select Messages->Apply Filters, then they are moved into the folder. Is there an option to make this filtering apply automatically to all new emails?
There is a setting in the account configuration somewhere where you can switch filtering on/off for that account. Maybe check if it's on?
