[Dovecot] is it possible to fetch messages for multiple users using a single account?
by Tony Smith 16 Oct '09

16 Oct '09

Dear list, I am running dovecot with LDAP. Each account has email in form abc(a)example.com, and messages are stored at /var/vmail/abc/Maildir. This is an external mail server, and I would like to use a cron job to fetch all messages to an internal server which has slow internet connection. It seems getmail supports multidrop retriever which might fit the bill. However I could not figure out how to set up an account that can be used to fetch all messages for all virtual accounts. Is it possible at all? thanks, Tony PS: here is my config: # dovecot -n # 1.1.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-openvz-amd64 i686 Debian 5.0.3 log_path: /var/log/dovecot.log protocols: pop3 pop3s imap imaps managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): 127.0.0.1:2000 ssl_cert_file: /etc/ssl/certs/cert.pem ssl_key_file: /etc/ssl/private/key.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_uid: 1000 mail_gid: 1000 mail_location: maildir:/%Lh/Maildir/:INDEX=/%Lh/Maildir/ mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota zlib mail_plugins(imap): quota imap_quota zlib mail_plugins(pop3): quota zlib mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): /var/vmail/sieve/%Ld/%Ln/ sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): dovecot.sieve auth default: mechanisms: plain login default_realm: river-valley.com user: vmail passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/dovecot-auth mode: 438 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: vmail group: vmail plugin: quota_warning: storage=85%% /usr/bin/dovecot-quota-warning.sh 85 quota_warning2: storage=90%% /usr/bin/dovecot-quota-warning.sh 90 quota_warning3: storage=95%% /usr/bin/dovecot-quota-warning.sh 95 quota: maildir quota_rule: *:storage=100M expire: Trash 7 Trash/* 7 Junk 30 expire_dict: proxy::expire auth_socket_path: /var/run/dovecot/auth-master dict: expire: db:/var/lib/dovecot/expire/expire.db

[Dovecot] virtual Folder Plugin with "." Separator: [NONEXISTENT] Mailbox doesn't exist
by Elmar Weber 16 Oct '09

16 Oct '09

Hello, I've switched from courier-imap to dovecot to benefit from the virtual folder feature. I'm using dovecot 1.2.6 on Gentoo Linux. However, I', getting the message "[NONEXISTENT] Mailbox doesn't exist: <name>" from Thunderbird when I try to access any virtual folder. The relevant setup: mail_location = maildir:~/.maildir namespace private { separator = . inbox = yes hidden = yes list = yes } namespace private { prefix = virtual. separator = . location = virtual:~/.maildir/.virtual } I then created the folders ~user/.maildir/.virtual and ~user/.maildir/.virtual.test and placed a file in .virtual.test with the contents ====== * all ====== After a dovecot restart I'm getting the error message: "[NONEXISTENT] Mailbox doesn't exist: test" Where did I make the mistake in the configuration? Is the "." path separator a problem case? ciao, Elmar

[Dovecot] Missing folders
by John Moorhouse 16 Oct '09

16 Oct '09

I've recently had a oops with the system I was running dovecot on so have had to move it to a new machine, I've been able to retrieve the mbox files from the old machine, built the new machine and over wrote the new mbox files with the old one in maildir, connecting to the server via imap woeks but I can only see the mail in the inbox from the old mbox files, emails in sub directories (the sub directories arn't there), is there some command I need to run to get it to pass the mbox file to find the folders or it there another file I need to transfer form the old machine. (I'm assuming that all the emails for a user, including those in subfolders are within the single mbox file, particularly as I'm is very large) Thanks John

[Dovecot] Dovecot lock problem
by Simon Gao 16 Oct '09

16 Oct '09

Hi, We have a few users experiencing locking problem. When starting Thunderbird, there is no new emails in Inbox. Dovecot createa a lock file /var/spool/mail/<user>.lock. It never completes openning Inbox. If closing the mail client, the open imap session does not get closed, nor the lock file get deleted. Here are the errors in log: dovecot: Oct 13 11:18:35 Warning: IMAP(user1): Our dotlock file /var/mail/user1.lock was deleted (kept it 88 secs) dovecot: Oct 13 11:18:35 Error: IMAP(user1): file_dotlock_delete() failed with mbox file /var/mail/user1: No such file or directory We are running Dovecot 1.1.2. Any pointer to resolve this problem is appreciated. Simon

[Dovecot] MailDIR and expire plugin
by Jerry 16 Oct '09

16 Oct '09

All of the mailboxes on this system are in MailDIR format. None of the users delete mail off of the server after POPing their accounts. This is the present setting: expire = Trash 7 Spam 30 expire_dict = proxy::expire Is that correct for MailDIR style mailboxes? It doesn't appear correct; however, I have not been able to find any specific documentation on expire with MailDIR style mailboxes. I am assuming that the expire plugin will work since IMAP has not been implemented on this server. -- Jerry |::::======= gesbbb(a)yahoo.com |::::======= |=========== |=========== | QOTD: "Wouldn't it be wonderful if real life supported control-Z?"

[Dovecot] Dovecot 1.2.6 segfault in imap_fetch_begin
by Brandon Davidson 16 Oct '09

16 Oct '09

We recently upgraded from Dovecot 1.2.4 to 1.2.6 (with the sieve patches of course). Everything has been running quite well since the upgrade. The occasional issue with assert-crashing when expunging has gone away. However, one of our users seems to have triggered a new issue. She's been the only one to see it, but whenever she logs in, her imap process segfaults immediately. It appears that the crash is a null pointer deref in the array library, but I'm not sure what code is at fault for calling in without checking array validity... or even if I'm on the right track. Backtraces and some further information are available here. Cores available on request. http://uoregon.edu/~brandond/dovecot-1.2.6/bt.txt Thanks, -Brad
