Dovecot Cur and New Directories are empty
by Nguyen Dinh Phuoc Thanh 14 Nov '14

Hi, Recently, we faced an issue with dovecot. Mail delivered to New directory, but after we used Outlook to connect with POP3 protocol, there was no email delivered to Outlook and New/Cur directory was empty. If we don't use Outlook to connect, after a few minutes, it is empty also. Would you please help me to solve this issue? Below is the result from "dovecot -n" --------------------------------------------------------------------- # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-504.el6.x86_64 x86_64 CentOS release 6.6 (Final) ext4 auth_mechanisms = plain login debug_log_path = /var/log/dovecot-debug.log dict { quotadict = mysql:/etc/zpanel/configs/dovecot2/dovecot-dict-quota.conf } disable_plaintext_auth = no first_valid_gid = 12 first_valid_uid = 101 info_log_path = /var/log/dovecot-info.log lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = * lmtp_save_to_detail_mailbox = yes log_path = /var/log/dovecot.log mail_debug = yes mail_location = maildir:/var/zpanel/vmail/%d/%n managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded- character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date imapflags notify passdb { args = /etc/zpanel/configs/dovecot2/dovecot-mysql.conf driver = sql } plugin { acl = vfile:/etc/dovecot/acls quota = maildir:User quota sieve = ~/dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +notify +imapflags sieve_global_dir = /var/zpanel/sieve/ sieve_global_path = /var/zpanel/sieve/globalfilter.sieve sieve_max_actions = 32 sieve_max_redirects = 4 sieve_max_script_size = 1M trash = /etc/zpanel/configs/dovecot2/dovecot-trash.conf } protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = mail mode = 0666 user = vmail } } service dict { unix_listener dict { group = mail mode = 0666 user = vmail } } service imap-login { inet_listener imap { port = 143 } } service imap { vsz_limit = 256 M } service lmtp { unix_listener lmtp { mode = 0666 } } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } service pop3-login { inet_listener pop3 { port = 110 } } ssl = no userdb { args = /etc/zpanel/configs/dovecot2/dovecot-mysql.conf driver = sql } protocol lda { mail_plugins = quota sieve postmaster_address = postmaster(a)###.com } protocol imap { imap_client_workarounds = delay-newmail mail_plugins = quota imap_quota trash } protocol lmtp { mail_plugins = quota sieve } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol sieve { managesieve_implementation_string = Dovecot Pigeonhole managesieve_max_compile_errors = 5 managesieve_max_line_length = 65536 } ---------------------------------------------------------------- Thanks, Thanh

automatically create Spam mailbox
by Cliff Hayes 14 Nov '14

14 Nov '14

I am trying to set up dovecot to automatically create a Spam mailbox for every user. http://wiki2.dovecot.org/MailboxSettings shows how to do this but not what config file to put it in so I assume 10-mail.conf. When I put it in there as follows... namespace inbox { mailbox Spam { auto = create special_use = \Junk } } ... I get the following error ... doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-mail.conf line 107: Unknown setting: mailbox How do I create the mailbox?

Core Dump upon startup (SEGV) - v2.2.10

In my recent messages I mentioned how I was having difficuilty in making my wife's email readable in Squirrelmail; this was solved with directory permissions. However, my usual email client is Thunderbird; I was holding off on using that as there appeared to be authentication issues. Today was my opportunity to start debugging those; it occurred to me that I might have issues with PKI and tried to make/install working certificates. When this didn't work, I though to just scrub the installation and start over. On my CentOS 7 system I erased and reinstalled from RPM. With what should have been working certificates, I ran through the config files, and then restarted to the following error: [root@dungeon dovecot]# systemctl -l status dovecot.service dovecot.service - Dovecot IMAP/POP3 email server Loaded: loaded (/usr/lib/systemd/system/dovecot.service; disabled) Active: failed (Result: core-dump) since Thu 2014-11-13 19:05:52 EST; 30min ago Process: 23700 ExecStart=/usr/sbin/dovecot -F (code=dumped, signal=SEGV) Process: 23695 ExecStartPre=/usr/libexec/dovecot/prestartscript (code=exited, status=0/SUCCESS) Main PID: 23700 (code=dumped, signal=SEGV) Nov 13 19:05:52 dungeon.the-leveys.us systemd[1]: Started Dovecot IMAP/POP3 email server.

Migrate system users to virtual users
by Ron Leach 13 Nov '14

13 Nov '14

List, good afternoon, We are at the planning stage of wanting to migrate from an existing installation onto a new machine, and also to change from system users to virtual users. May I check that our ideas for user id are correct? I am not sure whether we will encounter a 'permissions' and 'user id' problem when moving from a system-user scheme to a virtual scheme. We use Maildir, and the maildirs at the moment are in their users' linux /home directories. After reading the wiki, we think that the 'single system user for vmail' arrangement, ie just one system user to manage all the mail for all virtual users, will work for us. I think that means that the permissions on all our existing 'system-user-oriented' maildirs will have to be changed (in the new machine) so that they are owned by the 'single-system-user', such as 'vmail'. One thought was to first copy the existing maildirs into the new virtual user file system tree, and then, second, change the owners and permissions on the maildirs and directories and messages to permit control by 'vmail'. From the point of view of transferring all the mail files, is that all we would have to do? (Of course, we would also have to create the virtual users and their passwords, and arrange the appropriate password lookups etc, but that's not the direct topic of this post. And that arrangement has to be compatible with the MTA, as well.) If we do copy the maildirs and change the permissions, does all the metadata that the clients, or Dovecot, use to detect new, existing, or downloaded mail remain valid? Or should we use a different approach? Grateful for any comment regards, Ron

Bug (?) while listing imap folder

Dear All, I think I've hit a bug after migrating our mail server to the newest version of dovecot (version 2.2.15). When I try to list all imap folders for one user the imap process crashes. The listing to a specific folder (ex. INBOX) works fine, only the "*" crashes. Client side: --------------------- [root@mb log]# telnet 127.0.0.1 143 Trying 127.0.0.1... Connected to 127.0.0.1.

Hi, after upgrade to Dovecot >= 2.2.14rc1 sometimes I found this error/crash in the log (never happened with 2.2.13), I'm the only one? Can be fix? Nov 11 17:44:26 imap(info(a)myemail.com): Error: Corrupted transaction log file /home/domains/myemail.com/info/Maildir/dovecot.index.log seq 190: Invalid transaction log size (32756 vs 32772): /home/domains/myemail.com/info/Maildir/dovecot.index.log (sync_offset=32756) Nov 11 17:44:26 imap(info(a)myemail.com): Error: Log synchronization error at seq=0,offset=0 for /home/domains/myemail.com/info/Maildir/dovecot.index: Append with UID 10777, but next_uid = 10778 Nov 11 17:44:26 imap(info(a)myemail.com): Error: /home/domains/myemail.com/info/Maildir/dovecot.index view syncing failed to apply changes Nov 11 17:44:26 imap(info(a)myemail.com): Panic: file index-sync.c: line 265 (index_mailbox_sync_next_expunge): assertion failed: (range->seq2 <= ctx->messages_count) Nov 11 17:44:26 imap(info(a)myemail.com): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x75e1a) [0x7fbbd213ae1a] -> /usr/lib/dovecot/libdovecot.so.0(+0x75e96) [0x7fbbd213ae96] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7fbbd20ec2bf] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xb219c) [0x7fbbd245719c] -> dovecot/imap(imap_sync_more+0xc3) [0x41fd13] -> dovecot/imap() [0x420437] -> dovecot/imap(cmd_sync_delayed+0x209) [0x4208f9] -> dovecot/imap(client_handle_input+0x1ed) [0x4178dd] -> dovecot/imap(client_input+0x6f) [0x417b9f] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x5b) [0x7fbbd214c0db] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xaf) [0x7fbbd214d27f] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7fbbd214c169] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7fbbd214c1f8] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fbbd20f1193] -> dovecot/imap(main+0x2b0) [0x4210d0] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7fbbd1d81cad] -> dovecot/imap() [0x40bea9] Nov 11 17:44:26 imap(info(a)myemail.com): Fatal: master: service(imap): child 13586 killed with signal 6 (core dumped) # gdb /usr/libexec/dovecot/imap /home/domains/myemail.com/info/core Reading symbols from /usr/libexec/dovecot/imap...done. warning: Can't read pathname for load map: Input/output error.
