[Dovecot] dovecot: Fatal: IMAP(user2): write(event_pipe) failed: Bad file descriptor
by Mart Pirita 24 Apr '08

Hello. Since I upgraded few months ago from version 1.0 to 1.1 (right now using v1.1.rc4) in logs for some users only (but in different servers) I noticed errors: dovecot: Fatal: IMAP(user2): write(event_pipe) failed: Bad file descriptor dovecot: Fatal: IMAP(user3): write(event_pipe) failed: Bad file descriptor So only for some imap users. And in different servers. And this error happens suddenly, I already tried to delete delete cache and index files. However the users themselves haven't noticed any problems. Shall I just ignore these errors on what? Configuration is quite simple: dovecot -n # 1.1.rc4: /etc/dovecot.conf protocols: imaps pop3 pop3s ssl_parameters_regenerate: 0 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_log_format_elements: %u [%r] %m %c mail_max_userip_connections(default): 90 mail_max_userip_connections(imap): 90 mail_max_userip_connections(pop3): 9 maildir_copy_preserve_filename: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle netscape-eoh tb-extra-mailbox-sep delay-newmail imap_client_workarounds(imap): outlook-idle netscape-eoh tb-extra-mailbox-sep delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_logout_format(default): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(imap): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(pop3): bytes=%i/%o, del=%d/%m, size=%s auth default: cache_size: 1024 failure_delay: 3 passdb: driver: pam args: cache_key=%u%r%s * userdb: driver: passwd -- Mart

[Dovecot] Dovecot timeout over NFS
by Guy 24 Apr '08

24 Apr '08

Hi, I'm using postfix with Dovecot 1.0.5 and getting the following errors when a user moves a massive folders contents to trash (65000 or so messages): Apr 21 15:31:01 mink dovecot: IMAP(dev2(a)aluminati.net): Timeout while waiting for lock for transaction log file /virtual/store1/mail/d/dev2_aluminati.net/Maildir/.Deleted Items/dovecot.index.log Is there anything I can do to compensate for situations like this? Thanks Guy -- Don't just do something...sit there!

[Dovecot] Sieve script executed, but nothing happens
by Wouter Amsterdam 24 Apr '08

24 Apr '08

Hi all, I think I have almost solved my dovecot-deliver lookup problems, but now sieve still fails to work. From deliver's logfile I can tell the user's homedir is found and the sieve script is executed, but not as expected. My sieve testscript is very basic: /home/virtual/user.dovecot.sieve: ************* require "fileinto"; if address :is "to" "user@ mydomain.nl" { fileinto "sieve"; ( I also tried INBOX.sieve, without succes) } ************* But incoming messages for this account are still delivered in the normal inbox, not in the sieve folder. Why won't this work? /var/log/deliver: ************* deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: Loading modules from directory: /usr/lib/dovecot/lda deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: Module loaded: /usr/lib/dovecot/lda/lib90_cmusieve_plugin.so deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: auth input: user(a)mydomain.nl deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: auth input: home=/home/virtual/user deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: auth input: uid=5000 deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: auth input: gid=5000 deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: maildir: data=/data/mail/mydomain/user deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: maildir: root=/data/mail/mydomain/user, index=/data/mail/mydomain/user, control=, inbox= deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: cmusieve: Using sieve path: /home/virtual/user/.dovecot.sieve deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: cmusieve: Executing script /home/virtual/user/.dovecot.sievec deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: msgid=<20080417075530.5E8BD20111(a)termsrv.mydomain.local>: saved mail to INBOX ************* TIA, Wouter

[Dovecot] using mysql from within a plugin
by Alexander Prinsier 24 Apr '08

24 Apr '08

Hello, I'm trying to access a mysql database in a plugin. -What special compiler flags do I need? I discovered that when I don't explicitly link lib-sql/libsql.a in, then I get an undefind symbol error about sql_init when loading the plugin. Shouldn't the imap process itself have sql support linked in, rather than each plugin? -It appears that I need to call sql_drivers_init() and sql_drivers_register_all() before sql_init. Again, shouldn't the imap process do this, instead of each plugin? It should probably only be called once, so if one plugin already does it, then the second one will create problems. -When linking libsql.a in, and calling the functions mentioned above, then I get this error when starting dovecot: undefined symbol: mysql_ssl_set I'm guessing it's part of the mysql library itself, not dovecot. Can someone give me some hints on how to use dovecot's mysql library in a plugin? Thanks, Alexander

[Dovecot] Sharing Folders - or views?
by Nigel Allen 24 Apr '08

24 Apr '08

Hi All Running Dovecot v1.0.3 on FC 6. We have a Dovecot account which contains folders used by all staff. Think of the account as "Customers" and the folders as "Customer-1", "Customer-2", "Customer-3" and so on. We currently have around 650 of these customer folders. The problem is that there are currently 12 members of staff who need to see a subset of these folders (i.e. the customers that they are the manager for) but who also need to see (sometimes) the entire range of customer folders. Ideally what they would like to see is this kind of layout: +Personal Folders Inbox Trash Copies + My Customers Cust-1 Cust 7 Cust-25 Cust 33 + All Customers Cust-1 Cust-2 Cust-3 Cust-4 Cust-5 Cust-6 Cust-7 etc I suppose we could achieve this with symlinks but thought I would ask in case there is a "clever" way to achieve the same end. Thanks and Regards Nigel. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Windows Mobile and IMAP proxy
by Onno Molenkamp 24 Apr '08

24 Apr '08

Hi, We are running Dovecot proxies in front of our Dovecot IMAP servers, and were having problems with Windows Mobile clients not being able to connect. The clients would send a LOGIN command, and immediately after the succes reply a LOGOUT command. It turns out the Windows Mobile IMAP client gets confused by the IMAP proxy first sending the command tag in the reply and then, in a seperate packet, the rest of the line. Although not being able to handle this looks like a very bad design to me (how can one ever expect to read a full line in a single read() call?) I fixed it in our Dovecot proxies because we do have clients that want to use it. Attached is my fix for the problem. Onno
