[Dovecot] expire plugin + --exec-mail in 1.2.6 version
by Nikita Koshikov 25 Nov '09

25 Nov '09

Hello list, After upgrade to dovecot version 1.2.6 I have noticed some quota malfunctions(users become often overquota). Looking at logs closely I have found that quota value resets to general dovecot-config( quota = maildir:Mailbox quota quota_rule = *:storage=500M quota_rule2 = Trash:storage=10%% ), after dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool.sh command. The problem that some users have their own quotas stored in ldap. For example, user sr(a)domain.com have maildirsize before running expire-tool(1G value from ldap): # head -2 /data/mail/domain.com/sr/data/maildirsize 10485760000S 836423205 8285 Then I run expire-tool with mail_debug enabled: # /usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool.sh Info: Loading modules from directory: /usr/lib/dovecot/imap Info: Module loaded:

In changes to version 1.2.6 I see - dovecot --exec-mail was broken. Is fixes to 1.2.6 touch userdb lookups from --exec-mail ? With 1.2.4 expire-tool works correct and I have no config changes to dovecot setup. If dovecot -n output is needed, please let me know. Thanks.

[Dovecot] new to dovecot

Hi there, I have installed debian with exim4 postgresql 8.3 and dovecot 1.0.15. I have the mail delivery part done, so when i send mail it gets delivered in ~/MailDir/ I have tried to authenticate via passwd and postgresql but with no luck. I have read a lot on google but i cannot get dovecot to give me the mails via pop3. Is there a tutorial somewhere i have missed? so far i have messed up my config like this : # 1.0.15: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/errors.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:~/Maildir mail_debug: yes mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 pop3_uidl_format: %08Xu%08Xv auth default: verbose: yes passdb: driver: pam userdb: driver: passwd regards Lars Nielsen

[Dovecot] Newbee, some questions
by Spyros Tsiolis 24 Nov '09

24 Nov '09

Hello list, OK, I just registered with the list, so please be tolerant :-) I've been using another MTA for about, oh, I'd say nine years now. Due to reasons beyond me (mainly my clients demanding more for their buck / things like webmail etc.), I was forced to start searching for (always) open source alternatives. The last MTA was only POP3/SMTP. It does no webmail. It interfaces with other software with a lot of pain and difficulty. I'll cut to the chase. I would like to start using some kind of software that can do the following : 1. Do multiple domain handling. 2. Have a centralized user base 3. Have a centralized mail repository for each user (like exchange, only without the admin/maintenance pain that comes with it) 4. be able to do IMAP/POP3 and not SMTP/POP3 (or do I need all three of them ?) 5. Interface with things like web-based mail software (LAMP ?) Am I in the right place ? I would certainly like to think so. However, the feedback belongs to you . Thank you kindly for your hospitality and patience, S. Tsiolis

[Dovecot] shared mailboxes using namespaces in 1.2
by Alexander 'Leo' Bergolth 24 Nov '09

24 Nov '09

Hi! I've been using shared mailbox trees using maildir, unix permissions and separate namespaces per shared tree since dovecot 1.0. However now that I've upgraded to 1.2.8, I cannot create subfolders anymore. The server responds with "NO Invalid mailbox name: test/testsub". The hierarchy separator for the namespaces is / because I am mixing maildir and mbox namespaces and list=yes. The details: I am using a post-login script (attached) that detects all subfolders of /var/spool/mail/Shared for which the current user has at least read access. For every subfolder, it creates a separate namespace with the prefix Shared/<mailboxname>. The shared mailbox trees are in maildir format. If one of those namespace-prefixes is e.g. "Shared/sharedmailbox/", I am able to create "Shared/sharedmailbox/test" but trying to create "Shared/sharedmailbox/test/testsub" will fail with the above error. If I set the herarchy separator to '.' even creating "Shared/sharedmailbox/test" will fail. Any hints?

[Dovecot] Slow IMAP Auth
by Jeff Duncan 24 Nov '09

24 Nov '09

Hello, I am experiencing IMAP authentication delays when a client first authenticates, or after the last auth timeout. There are only a handful of clients - less than 5 - using the server. I am using a mysql database and I have verified the PAM auth is commented out. Other than that I can't figure out what might be causing the slow authentication. The first time a client authenticates with SSL/CRAMD5 it takes almost 20 seconds. Does anyone have any suggestions? My config and version is below: mail:~# dovecot --version 1.1.11 mail:/usr/share/gallery2# dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.3 ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s 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 mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(pop3): 10 first_valid_uid: 6060 mail_privileged_group: mail mail_location: maildir:/var/vmail/%d/%n mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): autocreate quota imap_quota mail_plugins(imap): autocreate quota imap_quota mail_plugins(pop3): quota 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 auth default: mechanisms: plain login cram-md5 passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf passdb: driver: sql

So...any idea? Thanks!

[Dovecot] Migrating existing local Maildir structure to dovecot server Maildir
by Halim Issa 23 Nov '09

23 Nov '09

Hello, I'm about to migrate a number of existing users who have been using POP3 with emails stored locally in KMail's Maildir format into an IMAP solution based on Dovecot. Will it be possible to simply move all the KDE Maildir folders from the local PCs to the Maildir folder on the IMAP server running Dovecot and then have the emails accessible on the server, or will this most likely mess up the Dovecot index files? If this causes index file trouble, is there any way to force a re-indexing of all these files, or is there another recommended way of migrating up to 7 years of email communication from local hosts to the IMAP server, for later putting them in folders? Thanks in advance! (PS. I noticed a few of the howto's on how to migrate to dovecot, but they only focus on moving from mbox to dovecot or similar, and not migrating existing Maildir emails to a new dovecot server... Any such pointers would be greatly appreciated :-)) -y1
