hi

i was carrying out some testing using qmailtoaster with dovecot on a centos 64 server

i am connecting to the mailbox using a windows machine with outlook across the lan.

the mailbox is around 7gb in size with around 12000 emails spread across multiple folders and i am trying to sync the mailbox folders to by creating an account imap account in outlook.

the mails are getting downloaded in the imap folder but the sync does not complete and outlook throws an error. Task 'Synchronizing subscribed folders for user@mydomain.com.' reported error (0x800CCC0F) : 'Outlook cannot synchronize subscribed folders for user@mydomain.com.. Error: The TCP/IP connection was unexpectedly terminated by the server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

in the dovecot log i see the following.

Apr 10 17:12:10 imap(user@mydomain.com): Debug: Effective uid=89, gid=89, home=/home/vpopmail/domains/mydomain.com/user Apr 10 17:12:10 imap(user@mydomain.com): Debug: Quota root: name=ignore=Trash backend=maildir args= Apr 10 17:12:10 imap(user@mydomain.com): Debug: Quota rule: root=ignore=Trash mailbox=? bytes=0 messages=0 Apr 10 17:12:10 imap(user@mydomain.com): Debug: Quota grace: root=ignore=Trash bytes=0 (10%) Apr 10 17:12:10 imap(user@mydomain.com): Debug: Namespace : type=private, prefix=, sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location= Apr 10 17:12:10 imap(user@mydomain.com): Debug: mdbox: access(/home/vpopmail/domains/mydomain.com/user/mdbox, rwx): failed: No such file or directory Apr 10 17:12:10 imap(user@mydomain.com): Debug: mdbox: couldn't find root dir Apr 10 17:12:10 imap(user@mydomain.com): Debug: sdbox: access(/home/vpopmail/domains/mydomain.com/user/sdbox, rwx): failed: No such file or directory Apr 10 17:12:10 imap(user@mydomain.com): Debug: sdbox: couldn't find root dir Apr 10 17:12:10 imap(user@mydomain.com): Debug: maildir: root exists (/home/vpopmail/domains/mydomain.com/user/Maildir) Apr 10 17:12:10 imap(user@mydomain.com): Debug: maildir++: root=/home/vpopmail/domains/mydomain.com/user/Maildir, index=, indexpvt=, control=, inbox=/home/vpopmail/domains/mydomain.com/user/Maildir, alt= Apr 10 17:12:40 imap(user@mydomain.com): Info: Disconnected: Logged out in=28 out=460

i would like to know what the following means -- specifically mdbox and sdbox

#################### Apr 10 17:12:10 imap(user@mydomain.com): Debug: mdbox: access(/home/vpopmail/domains/mydomain.com/user/mdbox, rwx): failed: No such file or directory Apr 10 17:12:10 imap(user@mydomain.com): Debug: mdbox: couldn't find root dir Apr 10 17:12:10 imap(user@mydomain.com): Debug: sdbox: access(/home/vpopmail/domains/mydomain.com/user/sdbox, rwx): failed: No such file or directory Apr 10 17:12:10 imap(user@mydomain.com): Debug: sdbox: couldn't find root dir ####################
