Hi everyone, We have implemented Postfix with Cyrus Imap in our Inc. It was working fine for quiet some time. But all of sudden a typical issue raised. All of sudden The users are not able to see their folders in their mail boxes including INBOX, SENT, TRASH etc... when logged in. Can somebody tell why this happened. For the above mentioned problem we have reconstructed all the mail boxes for about 1500 + users which took long time. Is there any thing related to quota for this problem, or any other ???? I have googled for a long time but couldn't crack where the problem is ??? and why it happened... Any suggestions would be appreciated and would be grateful. parameters in imap.conf file lmtp_over_quota_perm_failure: 1 quotawarn: 80 deleteright: d duplicatesuppression: true singleinstancestore: true unixhierarchysep: true altnamespace: true autocreatequota: -1 createonpost: true autocreateinboxfolders: Sent|Drafts|Trash|Junk autosubscribeinboxfolders: Sent|Drafts|Trash|Junk Please somebody give some solution for this ......I am worried .....if it again turns back It will be disaster for me.... cheers Albatross.......
