[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

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>

Re: [Dovecot] Dovecot "open files" (again?)

Does FreeBSD allow you to see /set the # of files a process can open with ulimit? Yep, in FreeBSD it's just "limits" which gives: Resource limits (current): cputime infinity secs filesize infinity kb datasize 524288 kb stacksize 65536 kb coredumpsize infinity kb memoryuse infinity kb memorylocked infinity kb maxprocesses 5547 openfiles 22190 sbsize infinity bytes vmemoryuse infinity kb 22190 is double the default. When I'm running without the issue (quota = dirsize) the # of open files is generally around 5k: # sysctl kern.openfiles kern.openfiles: 4910 When I change it, I can get it to go as high as I want (I then change dovecot back to dirsize for quota) sysctl kern.openfiles kern.openfiles: 19906 > 2. can you do an lsof (ls open files) and send that (zipped!!) over so I can see what it has open? I just tried, but being a busy time right now, doing "lsof -p [PID] > lsof.txt" never returns before the # of open files gets maxed and the server goes to hell. I'll have to try again at a slower time to see if it will return- right now's about the busiest time of day on this box. Is there anything in particular you're looking for in there? Most of the lines are similar to the ones in the attached (small!) text file. Thanks, falz

[Dovecot] considering dovecot
by Rick Hazey 15 Dec '06

15 Dec '06

Hi all. I'm making a case to use Dovecot over Courier and would like some feedback. I've searched the web extensively and have been unable to find any hard information regarding Dovecot's IMAP performance. I've got some pressure to use Courier but my gut tells me that Dovecot should be much faster. In particular, I will have typical users with mailboxes exceeding 10,000 emails and in some cases up to 100,000. Courier might be the "safe" choice but I'm not confident it can handle inboxes with that many messages. Dovecot, with its indexes, should be much, much faster. Can anyone point me to some benchmarks or production uses of dovecot that bear this out? From my research, Courier maildrop appears to be what I need for local delivery. Is it possible to use Maildrop for local delivery with Dovecot? Or is the Dovecot LDA needed to update the maildir indexes? I also need the capability for users to set their own vacation messages via a web page. Maildrop looks to handle this easily (by allowing me to link the maildrop filter to a file with the vacation message) but I don't see similar capability with the Sieve plugin. I do see where I can create a vacation message with Sieve but the text of the message seems to be required to reside within the Sieve script. Perhaps I'm missing something? Any feedback would be greatly appreciated.
