let's say someone has a message named 1215166123.52887_0.host.dom.ain:2, in his mailbox. That he accidentally deletes this mailbox (but it has been backed up somewhere by the administrator or some snapshot mechanisms). Then he receives a new mail. Can this new mail be named identically, i.e. 1215166123.52887_0.host.dom.ain:2, ? if so, it would be a problem when merging. > UNIX timestamp (seconds since 1970), PID and delivery counter. I guess that would be answer to the worry expressed above. > Dovecot doesn't really like if messages get "unexpunged" Why would messages be considered unexpunged (that would concern only messages which were previously tagged as "Deleted", right ?) ? Or do you mean that the index/cache mechanism would notice that messages have disappeared ? > dovecot-keywords could be a problem if the restored mail used keywords, > although it currently isn't a problem since keywords never get removed > so the existing dovecot-keywords file produces correct results. That > might change some day though. You mean that the following sequence cannot happen since keywords in dovecot-keywords never get deleted : . message M filename contain keywork b . message M gets deleted accidentaly . keyword b gets deleted from dovecot-keywords . message M is restored but the b keyword isn't known anymore ? So, apart from this keyword and unexpunged issues (the first one currently working and the second one having the "add a letter" workaround"), nothing prevents to merge (by simply copying messages in cur/) restored and new messages for the user (in the case it wouldn't be an option to let the user do the dirty job ;-)) ?
