9.3.3 Re-filing Reserved Messages

The three standard functions copy reserved messages to the archive folder, but do not delete them from the source folder. Because reserved messages and the like always remain, they are recorded in `~/.elmo/expired-alist' so that they are not copied over and over again. They are not recorded if copied by wl-summary-archive.

If you enabled logging, usually `move' is recorded for re-filing, but instead `copy' and `delete' are recorded separately if reserved messages are involved. This is because it actually copies messages including reserved, then deletes ones except reserved in that case.
