Hi all, I'm reading dovecot source codes(2.0.13),and I need to know how dovecot communicate with sasl? I traced the source code from cmd_login function,and found out something about sasl_callback. but i never found where this function called and also I couldn't understand how sasl inform the dovecot from authentication result. I'll be thankful if someone could help me out.

[Dovecot] Panic: doveadm quota get -A
by Urban Loesch 28 Jun '11

28 Jun '11

Hi, I'm new to the list and I'm using dovecot since 2 months. Still in progress to migrating from Stalker (Communigate Pro) to Dovecot. Today I upgraded from Dovecot 2.0.13-0~auto+27 (used form the Mirror xi.rename-it.nl - stable-auto) to 2:2.0.13-0~auto+48. List of installed packages: ii dovecot-common 2:2.0.13-0~auto+48 secure mail server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-imapd 2:2.0.13-0~auto+48 secure IMAP server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-lmtpd 2:2.0.13-0~auto+48 secure LMTP server for Dovecot ii dovecot-managesieved 2:2.0.13-0~auto+48 secure ManageSieve server for Dovecot ii dovecot-mysql 2:2.0.13-0~auto+48 MySQL support for Dovecot ii dovecot-pop3d 2:2.0.13-0~auto+48 secure POP3 server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-sieve 2:2.0.13-0~auto+48 sieve filters support for Dovecot It seems all is working fine, except "doveadm quota get -A". It gives me the following error: # doveadm quota get -A doveadm: Panic: file doveadm-print-table.c: line 58 (doveadm_calc_header_length): assertion failed: ((value_count % hdr_count) == 0) doveadm: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x3fd0a) [0x7fb901d0fd0a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7fb901d0fdf2] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7fb901ce916f] -> doveadm() [0x416bed] -> doveadm(doveadm_print_flush+0x1f) [0x40f1cf] -> doveadm() [0x40a92d] -> doveadm(doveadm_mail_try_run+0x11c) [0x40acfc] -> doveadm(main+0x381) [0x410761] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7fb901581c4d] -> doveadm() [0x409e09] Aborted I also tried the versions 2.0.13-0~auto+45 - 47 from xi.rename-it.nl. Same thing. Have you any idea how i can fix this. Downgrade to a 2.0.13-0~auto+27 is not possible because i have to fix this error to: http://hg.dovecot.org/dovecot-2.0/rev/09b8701362a4 Many thanks and regards Urban Loesch

Thanks. Solaris still uses /usr/lib/sendmail which is a pain since /usr/lib is rarely in shell search paths. Nothing a few symlinks can't fix. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Maildir parent directory permissions incorrect for new mailbox
by Dominic Marks 28 Jun '11

28 Jun '11

Hi, My issue is with the automatic creation of parent directories above new maildirs. It seems to be that they're being set with incorrect (or unhelpful) permissions, applying the permissions of the mailbox down the path towards the mailbox root, as opposed to taking the permissions of the mailbox root up towards the mailbox. Our mail is stored under the scheme: location = maildir:/var/dovecot/mail/%d/%n:INDEX=/var/dovecot/index/%d/%n Initially, /var/dovecot consists of acl, index and mail, all empty. The permissions on these are: >> ls -l total 6 drwxrwxr-x 2 hmgp hmgp 512 17 Jun 12:23 acl drwxrwxr-x 3 hmgp hmgp 512 17 Jun 15:56 index drwxrwxr-x 3 hmgp hmgp 512 17 Jun 15:56 mail If I perform a mail delivery to my mailbox, the mailbox parent directory is created with the following permissions: >> ls -l total 2 drwx------ 3 dm hmgp 512 17 Jun 15:56 insidetrading.co.uk Note that the user ID is my own and the mode restricts all other access. When I perform a second delivery to different mailbox under that domain, one mapped to a different UID, the delivery fails because that user cannot access the parent folder in order to create the new maildir. I've read on the Wiki that Dovecot copies permissions from the parent directory when adding new messages to a mailbox. That would suit my situation, but it doesn't happen here. Maybe there is there a reason why this is the case? I've had a look at the code and it it works in the opposite direction, starting from the full path (with its associated mode, uid & gid) and working by removing a section from the right-hand side each time. For me, at least, it would be better if it started from the bottom and worked upwards, inheriting the parent uid, gid and mode until the mailbox directory, where the existing behaviour would be retained, looking like: >> ls -dl insidetrading.co.uk/dm total 2 drwx------ 5 dm hmgp 512 17 Jun 15:56 dm I know I could hold all our mail under a single uid/gid or I could fix the mode manually, but I'd rather not do either. Am I missing some key configuration detail or should I work on a patch for this?

[Dovecot] UIDL and message migration
by Hugo Monteiro 28 Jun '11

28 Jun '11

Hello, I'm in the process of migrating accounts between two dovecot servers. An old server running ancient 1.0.15 and a new server running 1.2.15. Account migration is going to be gradual and so i would like to use imapsync to move messages and subscriptions from one server to the other. The only problem so far is with POP users. After doing an account migration with imapsync, and although both servers share the same pop3_uidl_format = %08Xu%08Xv, the client downloads every message that was already on the server. Any pointers would be very much appreciated. Best Regards, Hugo Monteiro.

[Dovecot] problem with dovecot and sieve
by Javier 28 Jun '11

28 Jun '11

Hi We've been using dovecot with great success so far. We are trying to add sieve support for our users. We enabled managesieve and users can define rules from the webmail (roundcube) with sieverules plugin for roundcube. Everything goes ok, but here's a problem I couldn't figure yet. When I define a redirect rule, the mail is forwarded but a local copy is stored too. Weird thing is that the logs say redirecting failed but the mail gets forwarded. Let me show you some of this (personal data masked): # cat .dovecot.sieve ## Generated by Roundcube Webmail SieveRules Plugin ## # rule:[teste] if anyof (true) { redirect "xxxxx@xxxxxxxxx"; } And the log from the user's sieve log sieve: info: started log at Jun 15 18:05:49. error: msgid=<BANLkTik1OzJEreF0qW000OvFpkaR7nOhCQ(a)mail.gmail.com>: failed to redirect message to <xxxxxx@xxxxxxx> (refer to server log for more information). syslog: Jun 16 11:40:26 mailstore5 dovecot: lmtp(8458, xxxxxxx(a)xxxxxx.com) Error: /eMhMNoV+k0KIQAAmtbU9A: sieve: execution of script /var/maildir++/99/xxxxxx(a)xxxxxxxx/.dovecot.sieve failed, but implicit keep was successful (user logfile /var/maildir++/99/xxxxxx(a)xxxxx.com/.dovecot.sieve.log may reveal additional details) And gets redirected anyway Jun 16 11:40:26 mailstore5 postfix/smtp[13041]: CB4D1C79FE: to=<xxxx@xxxxxxx>, delay=0.12, delays=0.02/0/0.01/0.08, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as E24FAB0880) There's no explicit keep anywhere in the sieve rule, nor a global rule, so Im confused, the email should be forwarded only. The error message confuses me too, as it says failed but the mail gets through. dovecot -n # 2.0.9: /opt/mail/dovecot/etc/dovecot.conf # OS: Linux 2.6.36.2 x86_64 Debian 5.0.8 auth_mechanisms = plain login base_dir = /opt/mail/dovecot/var disable_plaintext_auth = no listen = * mail_location = maildir:~/Maildir mail_plugins = create_mbox quota managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include varia passdb { args = socket=/opt/mail/auth_server/var/socket timeout=10 driver = courier } plugin { quota = maildir:User quota quota_rule = Trash:ignore quota_rule2 = Spam:ignore sieve = ~/.dovecot.sieve } protocols = imap pop3 lmtp sieve service imap-login { inet_listener imap { port = 30143 ssl = no } } service lmtp { inet_listener lmtp { address = 0.0.0.0 port = 30024 } process_min_avail = 4 } service pop3-login { inet_listener pop3 { port = 30110 } } ssl = no ssl_parameters_regenerate = 0 userdb { args = socket=/opt/mail/auth_server/var/socket timeout=10 driver = courier } protocol pop3 { mail_plugins = create_mbox quota maildiraccess pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_reuse_xuidl = no pop3_save_uidl = no pop3_uidl_format = %f } protocol imap { mail_plugins = create_mbox quota imap_quota maildiraccess } protocol lmtp { mail_plugins = create_mbox quota sieve } protocol sieve { mail_debug = yes } Your help is appreciated.

[Dovecot] Thunderbird or Dovecot causing duplicates
by Tim 28 Jun '11

28 Jun '11

Hey everyone, back on the list after a few years away. I have a strange issue that is just annoying. Trying to work out if it's Dovecot or Thunderbird causing the problem. Basically, I read an email (so it gets marked as read) and then very quickly I mark is as unread, (i.e. I realised I want to leave that email for later) which causes a duplicate email to be created. Generally I believe both duplicates are then marked as unread, but I've not taken too much notice of that part yet, other than the new email (the duplicate) being marked as unread. This has also happened when deleting emails from a junk folder. It seems to be events happening quickly that ether Thunderbird or Dovecot don't keep up with, so think the state of the message hasn't changed, so recreate the message maybe? I'm not really sure, so was hoping someone else had experienced the issue or could shed some light on it. Thanks Tim The logs from when I managed to recreate this manually this morning as a test.

[Dovecot] %d empty string
by Ryan Dotson 28 Jun '11

28 Jun '11

I am trying to upgrade from dovecot 1.x to Dovecot 2.0.13 on Fedora. My problem is the mail_location setting seems to ignore the %d variable. My my location is as follows: mail_location = maildir:/var/spool/virtual_mail/%d/%u/Maildir However, when trying to log in the maillog says it can't find /var/spool/virtual_mail//*myusername*/Maildir/cur. As you can see it just uses an empty string for the %d variable. Can anyone help? Thanks, Ryan
