Folders and filtering rules are managed together from webmail's Folders & rules page, linked in the sidebar.
Give a folder a name, or nest it inside another using "/" - for example
Work/Projects creates a "Projects" folder inside "Work".
Folders can be renamed or deleted from the same page; the system folders
(Inbox, Sent, Drafts, Junk, Trash) can't be renamed or deleted.
A rule matches incoming mail against a single condition and, on a match, files it straight into a chosen folder instead of the inbox:
For example, a rule matching From contains
invoices@supplier.com, moved to a folder named
Suppliers, files every message from that address straight into
that folder as it arrives.
Rules are checked in order, top to bottom, and the first match wins - a message only ever moves into one folder. Use the up/down arrows next to a rule to reorder it, and the toggle to pause a rule without deleting it.
Mail that's already been routed to Junk by spam scoring or a failed DMARC/SPF/DKIM check is never rescued by a filtering rule - rules only ever apply to mail that was headed for the inbox in the first place.
