If you *mv* the files there from a directory on the same filesystem, you should be fine, but if copy the files, I'd be careful. Probably you want to mimic the maildir behaviour: copy the files to tmp/ mv the files to cur/ (not sure, if new/ would be fine to, because new/ is the natural place after tmp/. I'm not sure, what this does to the message state the client sees.)

Thanks for the reply Heiko> About the 'cur' I'd not be too sure.Well, I'm just restoring to .Deleted Items, so it shouldn't be a problem. The tar restore should preserve names, permission, etc. I'll backup the current Maildir, the try the restore and see what happens. I'll report back. --Mark -----Original Message-----> Date: Thu, 12 Nov 2015 23:36:52 +0100 > From: Heiko Schlittermann <hs at schlittermann.de> > To: dovecot at dovecot.org > Subject: Re: How to Restore emails > > Hi, > > Mark Foley <mfoley at ohprs.org> (Do 12 Nov 2015 23:31:39 CET): > > According to a message to this list from Oli Schacher, > > http://www.dovecot.org/list/dovecot/2011-June/059493.html, all I need to do is copy the deleted > > emails to their original folder and dovecot will take care of it: > > > ??? > > > exactly, just copy the mail from your backup back into the users > > > maildir (usually into 'cur').

I'll report back.a problem will arise, if Dovecot indexes the directory when the file is not fully restorred, hence, changes later. Therefore, either prevent any access in Dovecot (deliver and retrieval) or use Heiko's approach, because mv is atomic on the same filesystem (rename instead of copy). The next problem comes with duplicates, because Maildir saves flags, keywords and status in the filename. I, therefore, copy a backup to another subdir, say "tmp2", then run fdupes (or similiar program) over cur, new and tmp2 to find duplicates, delete them in tmp2, and finally "mv -i " (you never know ;-) ) the remaining files from tmp2 to cur or new.> -----Original Message----- >> Date: Thu, 12 Nov 2015 23:36:52 +0100 >> From: Heiko Schlittermann <hs at schlittermann.de> >> To: dovecot at dovecot.org >> Subject: Re: How to Restore emails >> >> Hi, >> >> Mark Foley <mfoley at ohprs.org> (Do 12 Nov 2015 23:31:39 CET): >>> According to a message to this list from Oli Schacher, >>> http://www.dovecot.org/list/dovecot/2011-June/059493.html, all I need to do is copy the deleted >>> emails to their original folder and dovecot will take care of it: >>> >> ??? >>>> exactly, just copy the mail from your backup back into the users >>>> maildir (usually into 'cur').
