Documentation

When to expunge deleted messages.

If never, deleted articles are marked with the IMAP \Delete flag but not automatically expunged. If immediately, deleted articles are immediately expunged (this requires the server to support the UID EXPUNGE command). If on-exit, deleted articles are flagged, and all flagged articles are expunged when the group is closed.

For backwards compatibility, this variable may also be set to t or nil. If the server supports UID EXPUNGE, both t and nil are equivalent to immediately. If the server does not support UID EXPUNGE nil is equivalent to never, while t will immediately expunge ALL articles that are currently flagged as deleted
(i.e., potentially not only the article that was just deleted).

This is a Gnus server variable. See Info node (gnus)Select Methods.

Probably introduced at or before Emacs version 27.1.
