What is the -i for ? The -r was broken until last last 2.3.12 ! You must use $ reconstruct -r user/shortname/* to take care of subdirectories and add -f to discover unknown directories. Can you give more information about your system ? OS, cyrus version ? How long did it operate without problems ? Did you change anything ?

Try to reset the cyrus.index file before to reconstruct, because cyreconstruct could try to reuse it. something like # echo > cyrus.index or just delete it Regards > > Just a few things I tried if any of this helps. > > Thanks again for you help in advance > > Derrick > ---- > Cyrus Home Page: http://cyrusimap.web.cmu.edu/ > Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki > List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html > I am on a mac os x server 10.3.9 not sure how to find the cyrus version, naive i know... the -i is from one of apples documents on how to reconstruct the entire database for cyrus. the -r is for a single user, knowing now that it is broken makes a lot of sense with the problems i am having reconstructing. latest system changes was the installation of spamassassin with procmail for the relay. This i believe this caused my initial problem with the disappearing emails. Not to concerned about that right now, though i will be very happy to receive suggestions on that. Main problem is to get reconstruct working, I will deal with the disappearing emails later on, need to get them back now and be able to get them back reliably in the future until i fix the core problem with the disappearing emails. updated info that i found: when i take a look at the mailbox.db for the user that has a corrupted in box i get this.... myserver2:/var/imap user# sudo -u cyrus /usr/bin/cyrus/bin/ctl_mboxlist -d | grep brokenuser user.brokenuser default BROKENUSER lrswipcda user.brokenuser.INBOX^Drafts default brokenuser lrswipcda user.brokenuser.INBOX^Sent default brokenuser lrswipcda user.brokenuser.INBOX^Trash default brokenuser lrswipcda as you can see the inbox has the user in all caps, makes sense now why they can't get into there inbox, i believe this is case sensitive, so now how do i change this back to lowercase and or which reconstruct command (i know -r is broken) will work. I don't mind the broken construct if i can edit the mailbox.db successfully to fix the one issue with the caps. can always do up a script. i've checked other users, all of there info is in lowercase.... thanks Derrick ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
