01c52d31 | 25 | ;; This is the gnus-registry.el package, which works with all |
11a3174d | 26 | ;; Gnus backends, not just nnmail. The major issue is that it |
01c52d31 MB |
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 | |
23f87bed MB |
30 | |
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 | |
c024b021 TZ |
34 | ;; better documentation in the manual (also on my to-do list). |
35 | ||
36 | ;; If you want to track recipients (and you should to make the | |
37 | ;; gnus-registry splitting work better), you need the To and Cc | |
a6e77075 TZ |
38 | ;; headers collected by Gnus. Note that in more recent Gnus versions |
39 | ;; this is already the case: look at `gnus-extra-headers' to be sure. | |
