[Dovecot] mbox somewhere else?
by Tolga 19 Dec '06

19 Dec '06

Hi, I want to store my folders somewhere else, it used be in ~/mail. Is this as easy as moving everything in ~/mail to /var/mail/ and editing /etc/dovecot/dovecot.conf to read mail_location=mbox:~/mail:INBOX=/var/mail/%u ? Also, is the syntax mail_location=mbox:/var/mail/%u-folders:INBOX=/var/mail/%u correct? Regards, -- Whatever it is, I fear Greeks even when they bring gifts. -- Publius Vergilius Maro (Virgil)

Hi, just a note that FC6 now has the very latest of dovecot as an official update. :) It will upgrade the atrpms packages automatically to the official vendor version, there is nothing you need to take care of. -- Axel.Thimm at ATrpms.net

[Dovecot] Solaris NFS woes
by John Harper 18 Dec '06

18 Dec '06

I am using dovecot 1.0.rc15 (a similar problem occurred in rc10) on Solaris 9 (sparc). When working with a user who's home dir is on a local disk everything seems fine. But when that home is on an NFS-mounted disk things are very badly awry. Both the indices and the subscriptions file are being destroyed and what is left behind are files with names of the form .nfs72C034 etc. These files are described in the shell script nfsfind - every Solaris system ships with a root cron to run nfsfind and delete stale files: # These files are created by NFS clients when an open file # is removed. To preserve some semblance of Unix semantics # the client renames the file to a unique name so that the # file appears to have been removed from the directory, but # is still usable by the process that has the file open. I dont't see why dovecot would be unlink'ing it's active files while running - but I actually managed to see the dovecot.index.log appear briefly and then change to a .nfsXXXX file during the test user login. dovecot.index always seems to exist correctly but from local tests I know there should be a dovecot-uidlist, dovecot.index.cache, dovecot.index.log too, and these all appear to be .nfsXXXX files I can't seem to find anything relating to this specific problem in the archives, although these files have been mentioned a few times. And yes I do have mmap_disable = yes (but that is only relevant to the indexes, and the same thing is happening to the subscriptions file - ie some common library code for dealing with files has an issue) I should also note that these NFS mounts have been in existence for years and lots of things are running through them, so there shouldn't be anything wrong there. Suggestions, please?

[Dovecot] [PATCH] don't force read bit on base_dir
by Max Kellermann 18 Dec '06

18 Dec '06

Hi, I would like to disallow dovecot to read its base_dir (mode 0310). This is currently not possible, because settings_verify() in src/master/master-settings.c will "fix" the directory mode to 0750. The following patch for 1.0rc15 ignores the read bit (0444) when checking the directory permissions. Max

Re: [Dovecot] Problems with Mailstorage path.
by Raja T Nair 17 Dec '06

17 Dec '06

Hi, I have created symlinks to all the mail folders with caps in their name. but that does not solve the issue. If a user types in mixed case username( e.g. RtNaiR for rtnair ), dovecot creates a new mailfolder for that username; Is there a way to instruct dovecot not to create a mailbox and throw an error if the folder does not exist? raja.

[Dovecot] Proxy MD5/NTLM requests not working
by Cassidy B. Larson 16 Dec '06

16 Dec '06

Having some problems with setting up a proxy with any authentication mechanisms other than PLAIN. My passwords are stored in my database in plaintext (and MD5), so I figure I could use whatever scheme I want. Using the latest RC15. MySQL for the backend. This first one is CRAM-MD5. It fails (scheme_r != NULL??) then PLAIN tries to take over, but the auth server is restarting: Info: auth(default): client in: AUTH 1 CRAM-MD5 service=POP3 secured lip=204.x.x.x rip=209.x.x.x resp= Info: auth(default): client out: CONT 1 PDA1MTA2OTcxNzY0NjA1MTAuMTE2NjIwMjUxNkBtYXJiZWxsYS5pbmZvd2VzdC5jb20+ Info: auth(default): client in: CONT 1 YnV0Y2hAaW5mb3dlc3QuY29tIDBhNGNjNDJlN2QxOWI4ZjlkYjk0MjE2OTgxOGVmM2Ri Error: auth(default): file passdb-cache.c: line 120 (passdb_cache_lookup_credentials): assertion failed: (*scheme_r != NULL) Error: child 63406 (auth) killed with signal 6 Info: pop3-login: Authenticate PLAIN failed: Authentication failed: Authentication server isn't connected, try again later..: method=PLAIN, rip= 209.x.x.x, lip=204.x.x.x, TLS After this I tried adding this line to my Proxy dovecot-sql.conf file since the Destination already had it: default_pass_scheme = plain When I try connecting now, I get this: Info: auth(default): client in: AUTH 1 CRAM-MD5 service=POP3 secured lip=204.x.x.x rip=209.x.x.x resp= Info: auth(default): client out: CONT 1 PDg1NDgyMTgxOTgyNzI0NDIuMTE2NjIwMzg2MkBtYXJiZWxsYS5pbmZvd2VzdC5jb20+ Info: auth(default): client in: CONT 1 YnV0Y2hAaW5mb3dlc3QuY29tIDIzM2FjODE3NmMwNzZkNWE1MmZhNzdhNDJlODVmMjAy Info: auth-worker(default): sql(user(a)host.com,209.x.x.x): query: SELECT NULL AS password, v.storeIP AS host, v.userID AS destuser, 'Y ' AS nologin, 'Y' AS nodelay, 'Y' AS proxy FROM virtmailbox AS v WHERE v.userID = 'user(a)host.com' and v.imap_active = 1 Error: auth-worker(default): file passdb.c: line 120 (passdb_handle_credentials): assertion failed: (password != NULL) Error: child 69536 (auth-worker) killed with signal 6 Info: auth(default): client out: FAIL 1 user=user(a)host.com temp This last error is the same that I get when trying NTLM. Now, the password should be NULL, since I dont want to do any authentication on the Proxy, but simply forward it off to let the destination host handle it. Now the host that the proxy sends it off to works fine when I connect to it directly. I have the same default mechanisms allowed on both Proxy and destination. Anybody have any clues? I'd really like to figure out how to proxy "secure password" requests to my destination server without having to rely on plaintext. Plaintext works fine with the proxy, but I am unable to get anything else working. Am I overlooking something obvious? Thanks, Cassidy

[Dovecot] Trash and quota
by Kenny Dail 16 Dec '06

16 Dec '06

I can't seem to find the magic combination to get dovecot to ignore the trash folder when counting quota. I've got 1.0rc15 and using maildir quotas. Not being able to trash messages when over quota is quite annoying. the docs suggest the following: plugin { quota = maildir:storage=10240:ignore=Trash } but as my quotas are defined per user via mysql DB, I'm thinking that I need a modified version such as: plugin { quota = maildir:ignore=Trash } Which does not work. just in case it's a semantic problem, I also tried: plugin { quota = maildir:ignore=INBOX.Trash } which also doesn't work. I need other ideas of what to try to make it work if you please. -- Kenny Dail <kend(a)amigo.net>
