[Dovecot] Dovecot truncating messages and/or attachments
by fp＠kraptastic.com 21 Dec '07

Hello, I am having problems with Dovecot not sending clients emails bigger then 8-12k (it varies) or attachments bigger then 8-12k. I am also getting 'Corrupted transaction log file' errors ' unexpected end of file while reading header' I have deleted the dovecot.index.log, dovecot.index.cache, and dovecot.index several dozen times. I started off using Centos 5, with their package of dovecot 1.05, after seeing that there were problems in the package in the http://wiki.dovecot.org/WhyDoesItNotWork, I went with a source install of dovecot 1.09. Here is my cfg info: # dovecot -n # 1.0.9: /etc/dovecot.conf protocols: pop3 pop3s imap imaps ssl_cert_file: /etc/dovecert.pem ssl_key_file: /etc/dovekey.pem 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_process_size: 128 first_valid_uid: 106 last_valid_uid: 106 mail_extra_groups: mail mail_location: maildir:/var/spool/postfix/virtual/%d/%u mail_debug: yes maildir_copy_with_hardlinks: 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/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format: %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login user: vmail passdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: prefetch socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: vmail master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail (the login process is 128 because i was experimenting with various numbers (32,64,80,etc) The /var/log/maillog has hundreds of these: Dec 11 16:27:42 le1 dovecot: POP3(xxx@xxx): Corrupted transaction log file /var/spool/postfix/virtual/xxx.com/xxx(a)xxx/dovecot.index.log: unexpected end of file while reading header I turned made it so the mail stays on the server, so i can see that the mail stored there by postfix is the correct size.

So it does not appear to be a permission problem, it is reading and writing to the directory properly. The system is x86_64 centos 5, not using the standard dovecot nor postfix rpms that come with the distro. postfix from what I can tell, is working fine, but dovecot isn't. I'm going to try installing cyrus to make sure it's not postfix, but I'd really like to avoid cyrus if possible. Thanks in advance for any help.

[Dovecot] about quota_warning behavior
by naoki 21 Dec '07

21 Dec '07

Hi, We've been using v1.0.5 +quota_warning patch, however quota_warning does't seem to be working properly. For example, in order to enable 80% over for quota warning, and we configured like following: ----------------------------------------------------------------------- plugin { quota_warning = storage=80%% /usr/local/path/to/plugin } ----------------------------------------------------------------------- But it does not work. However we set quota_warning value to 20%, it seems to be working. ----------------------------------------------------------------------- plugin { quota_warning =storage=20%% /usr/local/path/to/plugin } ----------------------------------------------------------------------- If this is the case, do we always have to set quota value to what we have after subtracting the required quota warning value from 100. for example, if we want quota warning value to be 70%, we actually have to write 30% in configuration?? Will there be another patch to fix this? Thanks -- Naoki Takazawa Marino Ltd., Yokohama, JAPAN

Re: [Dovecot] 1.1.Beta9 deliver problem: Unknown mail storage driver raw
by ja nein 21 Dec '07

21 Dec '07

Hi Velko, I recently hit the same problem. You have to add raw storage driver to your compile options, meaning "--with-storages=maildir,mbox,dbox,raw,cydir", that will do the trick. Maybe it would be good to update the description of available storage drivers in configure script.

[Dovecot] 1.1 beta 11 - no quota warnings
by adam_jh＠hotmail.com 21 Dec '07

21 Dec '07

Having tried and failed to get 1.0.8 with quota-rewrite to send warnings, I removed the 1.0.8 and installed the latest 1.1 - however I still can't get the warnings! Can someone advise what might be wrong - it must be my configuration?? To compile 1.1 I used ./configure --with-deliver --with-mysql. I've chopped and changed my conf till I'm blue in the face. My dovecot-mysql.conf file does not override the quota, I've enabled the debug and verbose = yes - but they don't mention any quota warnings, just normal delivered logs. What else can I do? The process I use is to add up the maildirsize totals, set a storage figure in the conf which makes the maildirsize just less than 95%, then restart dovecot, send an email - and nothing - no warning is triggered! Any help appreciated - I've spent so long on this now. adam # 1.1.beta11: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 pop3s ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot-login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_extra_groups: mail mail_location: maildir:/var/vmail/%d/%n mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: user: nobody verbose: yes debug: yes passdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth user: postfix group: mail master: path: /var/run/dovecot/auth-master user: vmail group: mail plugin: quota: maildir quota_rule: *:storage=220000b quota_warning: storage=95%% /usr/local/bin/quota-warning 90

[Dovecot] imap+unix users and pop3+virtual users
by Wendell Turner 21 Dec '07

21 Dec '07

This should be simple, but I'm missing something. My virtual users cannot access their mail. I would like Unix users to get their mail via imap which is deposited in /var/spool/mail/username. (This works.) I would like virtual users to get their mail via pop3 which is deposited in /var/spool/mail/vhosts/example.com/auser/mail/inbox (postfix does in fact put the mail there). Those users can get authenticated via file /var/dovecot/passwd, but cannot retrieve their mail. The log message is shown below. The file/directory is there, but doesn't dovecot see it? Thanks, Wendell -------------------- Info: POP3(auser(a)example.com): mbox: data=/var/spool/mail/vhosts/example.com/auser/mail/:INBOX=/var/mail/auser@e… Info: POP3(auser(a)example.com): mbox: root=/var/spool/mail/vhosts/example.com/auser/mail, index=/var/spool/mail/vhosts/example.com/auser/mail, inbox=/var/mail/auser(a)example.com Info: POP3(auser(a)example.com): Mailbox init failed top=0/0, retr=0/0, del=0/0, size=0 -------------------- /usr/sbin/dovecot -n # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log protocols: pop3 imap imaps pop3s ssl_cert_file: /etc/CA/cert.pem ssl_key_file: /etc/CA/key.pem 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 mail_location: mbox:~/mail/:INBOX=/var/mail/%u mail_debug: 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 auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: pam passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/spool/mail/vhosts/%d/%n

[Dovecot] upgrade to 1.1 and mail location
by lenny＠edpausa.com 21 Dec '07

21 Dec '07

I recently upgraded from 1.0.8 to 1.1-11 the only thing that was changed in the config file was the new syntax for mail location. default_mail_env = mbox:~/:INBOX=~/mbox to mail_location = mbox:~/:INBOX=~/mbox now some imap clients, like squirrellmail and pine have difficulties writting to Sent, Draft and sent-mail folders. In all cases the folders are visible and are present in .subsriptions file( although not seen as subscribed in squirrelmail), but the clients complain that folders already exist when trying to write to them after sending. has anyone run into this ? any suggestions ? thanks a lot.

[Dovecot] v1.1.beta11 quota plugin and dict server

[Dovecot] minor issue - dovecot -n output with 1.1.beta11
by arvids 21 Dec '07

21 Dec '07

Hello, when running diff for 'dovecot -n' outputs from beta10 and beta11(for the same config file), I noticed that 'dovecot -n' beta11 output does not show anymore the following parameters, which are set to non-default values(and which 'dovecot -a' shows): login_processes_count login_max_processes_count first_valid_uid first_valid_gid cache_size cache_ttl cache_negative_ttl mode(from auth default section) And by the way, parameters from lda section are not showed both with -a and -n. But it is so already for a long time, so I assume that it is OK :) Regards, Arvids

[Dovecot] Dirsize quotas with 1.1beta9
by Dean Brooks 21 Dec '07

21 Dec '07

Hi, Anyone able to get 'dirsize' quotas to work properly under 1.1beta9? I can get them to reflect the size of the INBOX properly, but it never seems to be adding up the size of the files in the folder directory itself. I'll keep hammering away at it if others are able to use dirsize with no problems, but wanted to check first. -- Dean Brooks dean(a)iglou.com
