[Dovecot] Squirrelmail + Dovecot + Maildir
by Vicki Stanfield 21 Dec '07

21 Dec '07

I have been struggling with getting my Fedora 7 box set up to use dovecot with Squirrelmail and Maildir. It works correctly with the exception of writing outgoing mail to the right folder (.Sent) or drafts (.Drafts). If I send a mail with Mutt, it writes the mail to the right place, so it has to be squirrelmail config or dovecot config. I want to use .Sent for sent-mail (~user/Maildir/.Sent) and .Drafts for drafts (~user/Maildir/.Drafts). Here is what I see in /etc/squirrelmail/config.php $optional_delimiter = '.'; [snip] $default_folder_prefix = ''; $trash_folder = 'Trash'; $sent_folder = 'Sent'; $draft_folder = 'Drafts'; $default_move_to_trash = true; $default_move_to_sent = true; $default_save_as_draft = true; The error in the browser is: * ERROR : Bad or malformed request.* Server responded: {830} BAD Error in IMAP command : Unknown command. and in the logs I see this: Dec 18 09:41:56 opus postfix/smtpd[12747]: connect from localhost[127.0.0.1] Dec 18 09:41:56 opus postfix/smtpd[12747]: 4CB7329B00B2: client=localhost[127.0.0.1] Dec 18 09:41:56 opus postfix/cleanup[12750]: 4CB7329B00B2: message-id=<51150.127.0.1.1.1197988916.squirrel(a)127.0.1.1> Dec 18 09:41:56 opus postfix/qmgr[2650]: 4CB7329B00B2: from=<vic(a)thepenguin.net>, size=1015, nrcpt=1 (queue active) Dec 18 09:41:56 opus postfix/smtpd[12747]: disconnect from localhost[127.0.0.1] Dec 18 09:41:56 opus dovecot: imap-login: Login: user=<vic>, method=PLAIN, rip=::ffff:127.0.1.1, lip=::ffff:127.0.1.1, secured Dec 18 09:41:56 opus dovecot: IMAP(vic): Disconnected: Too many invalid IMAP commands.

[Dovecot] namespace problem / 1.1beta11
by ja nein 21 Dec '07

21 Dec '07

Hi all, actually I got a problem with the namespaces in dovecot 1.1 beta11. It occured after purging index files and resynch via imapsync. Dovecot complains about "Unknown namespace", though it worked with versions before. I cannot comfirm for 1.1beta10, but I surely know 1.1beta9 worked with these settings. Example: From Folder [INBOX/Trash] To Folder [___________] To Folder ___________ does not exist Creating folder [___________] Couldn't create [___________]266 NO Unknown namespace. Used imapsync command: /home/imapsync/imapsync --host1 ip.of.host.1 --user1 user1 --password1 password --host2 127.0.0.1 --user2 user2 --password2 password --authmech2 LOGIN --regextrans2 s/\./_/g --delete2 --sep1 . --sep2 . --justfolders Another run with different namespace settings shows up the folders in Thunderbird as INBOX^2002, INBOX^Trash ans so on... My goal is to keep all client settings when migrating a bigger installation of cyrus to dovecot. For know all folders in Cyrus appear as subfolders of INBOX, which I had achieved with dovecot < 1.1beta11. Any ideas? Btw., as we work in a load balanced environment, LMTP delivery would be a great feature for upcoming releases, as it would enable people to use multiple frontends of SMTP servers without the need of connecting them to a somewhat shared file system. Forwarding all mail to a SMTP server on the machine running dovecot and doing delivery there isn't the favoured option (at least for us). And a huge thx to Timo on working that hard on such a great working product!

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

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.

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

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
