Hello Michael Menge, you wrote: > Did you have a look at the mailboxes_dmp.txt file? Maybe it is corrupt? > I would search for user.foobar At first (quick) sight the file seemed to be correct. Here is an extract of a box which had the problem (I added the blank lines and replaced tabs by spaces): --- cut --- user.catherine^cudorge default catherine.cudorge lrswipcda user.catherine^cudorge.&AMk-l&AOk-ments envoy&AOk-s default catherine.cudorge lrswipcda cyrus lrswipcda catherine^cudorge lrswipcda user.catherine^cudorge.Brouillons default catherine.cudorge lrswipcda cyrus lrswipcda user.catherine^cudorge.Courriers non d&AOk-sir&AOk-s default catherine.cudorge lrs cyrus lrs user.catherine^cudorge.Courriers non d&AOk-sir&AOk-s.A recevoir default catherine.cudorge lrswipcd cyrus lrswipcd user.catherine^cudorge.Courriers non d&AOk-sir&AOk-s.A rejeter default catherine.cudorge lrswipcd cyrus lrswipcd user.catherine^cudorge.Courriers non d&AOk-sir&AOk-s.D&AOk-tection automatique default catherine.cudorge lrswipcd cyrus lrs user.catherine^cudorge.El&AOk-ments envoy&AOk-s default catherine.cudorge lrswipcda cyrus lrswipcda user.catherine^cudorge.INBOX default catherine.cudorge lrswipcda cyrus lrswipcda user.catherine^cudorge.Trash default catherine.cudorge lrswipcda cyrus lrswipcda user.catherine^cudorge.archives default catherine.cudorge lrswipcda cyrus lrswipcda catherine^cudorge lrswipcda --- cut --- Except a weird "catherine^cudorge lrswipcd" for two mailboxes in the acl, entries seems to be normal. In fact I managaged to solve the problem by removing the quota file in /var/lib/imap/quota/x/<user>/ and using "quota -f" on the mailboxes. But I still get repeating error messages like this: Jul 7 14:58:51 mail7702 lmtpunix[8988]: DBERROR db4: 9 lockers Jul 7 15:04:24 mail7702 lmtpunix[9249]: DBERROR db4: 11 lockers Should I be worried by these messages ?
