25 ;; This is the gnus-registry.el package, which works with all
26 ;; Gnus backends, not just nnmail. The major issue is that it
27 ;; doesn't go across backends, so for instance if an article is in
28 ;; nnml:sys and you see a reference to it in nnimap splitting, the
29 ;; article will end up in nnimap:sys
31 ;; gnus-registry.el intercepts article respooling, moving, deleting,
32 ;; and copying for all backends. If it doesn't work correctly for
33 ;; you, submit a bug report and I'll be glad to fix it. It needs
34 ;; documentation in the manual (also on my to-do list).
36 ;; Put this in your startup file (~/.gnus.el for instance) or use Customize:
38 ;; (setq gnus-registry-max-entries 2500
39 ;; gnus-registry-track-extra '(sender subject recipient))
41 ;; (gnus-registry-initialize)
43 ;; Then use this in your fancy-split:
45 ;; (: gnus-registry-split-fancy-with-parent)
47 ;; You should also consider using the nnregistry backend to look up
48 ;; articles. See the Gnus manual for more information.
52 ;; - get the correct group on spool actions
54 ;; - articles that are spooled to a different backend should be moved
