[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

[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

[Dovecot] dovecot ignoring folder permissions on directory creation
by Peter 23 Nov '09

23 Nov '09

Ubuntu 8.04lts Dovecot 1.2.6 So, further to the 'deliver' problem posted yesterday I've also discovered another issue regarding permissions: files and directories are being created 0600/0700 by the IMAP and deliver process (depending on who gets there first!) preventing use of shared mailboxes. According to documentation: "When creating a new mailbox, Dovecot v1.2+ copies the permissions from the mailbox root directory." and "When creating new files inside a mailbox, Dovecot v1.2+ copies the read/write permissions from the mailbox's directory." (http://wiki.dovecot.org/SharedMailboxes/Permissions) So, with an empty directory of: drwxr-xr-x 3 root root 21 2009-11-16 13:36 /home drwxrwx--x 3 nobody maildir 21 2009-11-16 13:36 /home/mail I would expect a user logging in to have their mail directory created automatically with the same permissions (but not necessarily the same group). What I see post-login is: drwxrwx--x 3 nobody maildir 21 2009-11-16 13:42 /home/mail drwx------ 3 auser adomain 18 2009-11-16 13:42 /home/mail/adomain drwx------ 3 auser adomain 20 2009-11-16 13:42 /home/mail/adomain/auser drwx------ 5 auser adomain 4096 2009-11-16 13:42 /home/mail/adomain/auser/Maildir drwx------ 2 auser adomain 6 2009-11-16 13:42 /home/mail/adomain/auser/Maildir/cur -rw------- 1 auser adomain 0 2009-11-16 13:42 /home/mail/adomain/auser/Maildir/dovecot-acl-list -rw------- 1 auser adomain 156 2009-11-16 13:42 /home/mail/adomain/auser/Maildir/dovecot.index.log -rw------- 1 auser adomain 17 2009-11-16 13:42 /home/mail/adomain/auser/Maildir/dovecot-uidlist -rw------- 1 auser adomain 8 2009-11-16 13:42 /home/mail/adomain/auser/Maildir/dovecot-uidvalidity -rw------- 1 auser adomain 0 2009-11-16 13:42 /home/mail/adomain/auser/Maildir/dovecot-uidvalidity.4b0156e2 drwx------ 2 auser adomain 6 2009-11-16 13:42 /home/mail/adomain/auser/Maildir/new drwx------ 2 auser adomain 6 2009-11-16 13:42 /home/mail/adomain/auser/Maildir/tmp I've tried pre-creation of /home/mail/adomain, /home/mail/adomain/auser and /home/mail/adomain/auser/Maildir in each case with permissions 0770 but in each case subsequent subdirectories and files are 0700/0600. I've also tried use of a "dovecot-shared" file, but this also has no effect under any permutation I can create. Anyone else seen this?

[Dovecot] Dovecot on Qnap ts-439
by BeKi 23 Nov '09

23 Nov '09

Hello, I use Xdove 1.2 on my ts-409 together with IMAP/dovecot. I like to see the same folder structure on my different workstation (private/work ...). I move the mails into the folder structure I created. That works fine. But since I use Xdove with IMAP I have the problem that my mailclient loads all mails I already stored in different folders again into the INBOX (some mails also multiple with subfolders). These mails are duplicates (or multiples) because I delete them all. The mails in my folders are still there. Up to now I tried different mail clients. Thunderbird 2.x/3.x, Pegasus 4.5, Outlook Express. All behave the same way, so I think it must have something to do with the server. The times when the clients loads the mails into INBOX are not regular intervals. It can be a day when this happens again or one week. Maybe one of you heard about this and can give me hints where to look for. Which configuration files shall I post to help debug? Thanks, Bernd

[Dovecot] lda deliver + vpopmail
by Stéphane Cottin 23 Nov '09

23 Nov '09

Hi all, I'm enjoying using dovecot deliver with qmail+vpopmail+dspam. It works mostly fine, I like the indexing and sieve features with dovecot deliver. I would like to get more details on trouble, the log entry is just : " 2009-11-18_20:38:55.64778 delivery 50833: deferral: " As you see, there no reason for the deferral. How can I make deliver more verbose ? I also have a vpopmail alias issue. Because some domains (sadly) needs a catchall, and to keep using the useful vpopmail alias features, I'm using the following ugly script : " #!/bin/sh email=`/usr/sbin/valias -- $1 2>/dev/null | cut -d" " -f3` if [ -z "$email" ];then email=$1 t=`/usr/sbin/vuserinfo -n -- $1 2>&1>/dev/null` t=$? if [ "$t" == "255" ];then domain=`echo "${1}" | cut -d'@' -f 2` dir=`/usr/sbin/vdominfo -d $domain 2> /dev/null| head -1` email=`cat ${dir}/.qmail-default | head -1 | awk -F# '{ print $2 }'` if [ "$email" == "bounce-no-mailbox" ];then email=$1 fi fi fi echo $email " my .qmail-default file contains : " #bounce-no-mailbox | /usr/bin/dspam --client --deliver=innocent,spam --user `/usr/sbin/vrealemails $EXT@$USER` --stdout | /usr/bin/preline -f /usr/lib/dovecot/deliver -d `/usr/sbin/vrealemails $EXT@$USER` " or if using a catchall : " #catchall(a)domain.com | /usr/bin/dspam --client --deliver=innocent,spam --user `/usr/sbin/vrealemails $EXT@$USER` --stdout | /usr/bin/preline -f /usr/lib/dovecot/deliver -d `/usr/sbin/vrealemails $EXT@$USER` " I don't like this way for design and security reasons and would prefer a more consistent approach. The vpopmail alias lookup should be made internally by deliver, and unlike my script, handle one to many aliasing. The catchall feature is (sadly) also needed, my implementation is ugly, in practice it works, but is limited as the catchall address must be on the same host. I'm thinking about adding a specific option to the deliver command line, but I'm not sure that's the better way to do it. Help needed please Stéphane

[Dovecot] .temp file, public folders
by Mayer 23 Nov '09

23 Nov '09

We recently migrated from UW-Imap to dovecot. Our setup: dovecot 1.2.6 postfix 2.3.3 (from rhel) systemusers without shell access to the mailstore location = maildir:/maildir/%1n/%u:LAYOUT=fs All mails on local disks. Performance is great compared with mbox. But I still have some unresolved problems, mainly concerning deliver. Deliver sometimes wants to write a .temp.<hostname>.some-number file in the user's home directory. If the user is over quota (in his home!) he can't receive mails though no mails are stored in his home. The user homes are on a distributed filesystem (AFS). The mails are stored locally on the mailserver as I mentioned before. How can I tell deliver in the configuration to write the temp file at another location ? We would like to offer public folders for work groups. Reading with imap works fine. But I didn't find a way to tell deliver to drop mails directly in a public folder. Should I use Sieve instead ? Maybe this is rather a postfix question. Postfix is calling deliver. Userdb in the dovecot config is passwd. Postfix looks for local users in: local_recipient_maps = $alias_maps $recipient_canonical_maps unix:passwd.byname Any help is appreciated. Helga Mayer

Hi All, Our webmail having an issue with the harddrive so I build new webmail on other machine (using Squirrelmail+dovecot+postfix). After copy all data/home folder from the backup, when this user want to access his Sent item, nothing's in it. I've checked the log and found the message as below. mailserver dovecot: IMAP(xxxxx): mbox sync: UID inserted in the middle of mailbox /home/xxxx/mail/Sent (691 > 657, seq=473, idx_msgs=10950) mailserver dovecot: IMAP(xxxxx): mbox sync: UID inserted in the middle of mailbox /home/xxxx/mail/Sent (691 > 657, seq=473, idx_msgs=10950) This is only happen with the Sent items, since I also found other similar log and this user advised that everything is fine with that folder mailserver dovecot: IMAP(xxxxx): mbox sync: UID inserted in the middle of mailbox /home/xxxxx/mail/Accountant Info (327 > 326, seq=306, idx_msgs=353) mailserver dovecot: IMAP(xxxxx): mbox sync: UID inserted in the middle of mailbox /home/xxxxx/mail/Accountant Info (327 > 326, seq=306, idx_msgs=353) I've rebuild the index file by delete the Sent item folder in .imap directory, no such luck. Any help would be really appreciated Thank you

[Dovecot] NONEXISTENT status code
by Michael M. Slusarz 23 Nov '09

23 Nov '09

I'm going to take exception to the way dovecot (1.2.8) is returning the NONEXISTENT response code in certain cases. For example, these transactions: c: 1 EXAMINE "foo" S: 1 NO [NONEXISTENT] Mailbox doesn't exist: foo C: 2 STATUS "foo" (MESSAGES) S: 2 NO [NONEXISTENT] Mailbox doesn't exist: foo ...don't appear to be the proper usage of NONEXISTENT. From RFC 5530[3]: NONEXISTENT The operation attempts to delete something that does not exist. NONEXISTENT should be used for RENAME or DELETE (also the UID EXPUNGE) commands. Although the textual description is appropriate in the above situations - the mailbox truly doesn't exist - this is not what the response code indicates. Under the RFCs, it seems that failure of a STATUS or EXAMINE command with a NO response *could* mean the mailbox doesn't exist, but there is no method of reporting this via a response code. michael

[Dovecot] Upgrade Dovecot 1.2.7 to 1.2.8 on OS X (10.6.2)
by Tom Kardos 23 Nov '09

23 Nov '09

Hi there, I've tried to update Dovecot to the latest version and have come upon an error during make. Previous upgrades have all been very easy (thank you!) and it appears that the updated make script includes a wget command and unfortunately OS X does not come with wget by default (curl is the default). Not being completely up to speed with the whole autoconf and make process, I'm a little at a loss as to where to even look for making a modification to use curl instead of wget - any assistance would be appreciated. Thanks in advance Tom

[Dovecot] quota in SQL and static userdb
by Lampa 23 Nov '09

23 Nov '09

Hello, which solution will be working or will be working better (performance). Using dovecot 1.2.6 (plugin section contains quota_rule = *:storage=500M:messages=10000 and i need override this default quota for some users) A) passdb sql(SELECT userid AS user, pw AS password, quota AS userdb_quota_rule FROM users WHERE userid = '%u') + userdb static (uid=500 gid=500 home=/home/mail/%d/%n allow_all_users=yes) - using extra fields quota with no prefetch userdb or B) passdb sql(SELECT userid AS user, pw AS password, quota AS userdb_quota_rule, CONCAT('/home/mail/', domain, '/', user) AS userdb_home, 500 AS userdb_uid, 500 AS userdb_gid FROM users WHERE userid = '%u') + prefetch (eg same sql file) Solution for LDA only(postfix local delivery) and for another IMAP/POP3 dovecot instance? And how to implement domain quotas (something like user quotas using dict) ? Thank you. -- Lampa

[Dovecot] How to remove leading dots from folder names with Layout=FS
by Tony Rutherford 23 Nov '09

23 Nov '09

We are looking to move to Dovecot from a customized Courier implementation. Our current format is maildir-like. It's basically a filesystem layout...hierarchies are identified by real directories/subdirectories. Our folder names do have a leading dot and for reasons related to other systems, we do not want to change our format at all.The Layout=FS is very close to working for us. The problem we have is the folder names are coming back with the leading dot to the clients. Is there a way through configuration to have the leading dot removed?So, just to clarify, under our maildir home, we have directories (folders) for example: .Trash, .Sent-Mail, etc. Then, any child folders would be resident in the physical subdirectories. Like I said, things appear to work ok, except our List is coming back with .Trash, .Sent-Mail, etc....we would like simply Trash, Sent-Mail, etc.Thanks,...Tony This message is intended solely for the individual(s) to whom it is addressed. If you are not the intended recipient, any dissemination or copying is strictly prohibited. If you believe you received this message in error, please notify the sender and delete from your system. Thank you.

[Dovecot] trivial documentation errata (1.2.7)
by Frank Cusack 23 Nov '09

23 Nov '09

The default dovecot.conf says # Dictionary can be used by some plugins to store key=value lists. # Currently this is only used by dict quota backend. Looks like expire uses dict as well. The managesieve comments are stale as well, with a reference to sieve_storage still in there. Or do they refer to the CMU sieve implementation? Anyway it is confusing. -frank

[Dovecot] [OT] preferred clients
by Jonathan 23 Nov '09

23 Nov '09

I'm getting tired of Thunderbird telling me I have unread messages in folders that haven't gotten new messages for months so I'm looking for a new mail client. I know the problem lies with Thunderbird because everything is fine via RoundCube and if it tell Thunderbird to rebuild it's index it shows the folder correctly again. Except of course for a subset of the messages in my inbox that it insists where delivered at the exact time I re-indexed it, every time. So what IMAP clients do people prefer these days? Preferably windows or cross platform and it needs to have decent key bindings because (probably like many of you) I get 100s of emails a day via lists and anything that speeds my way through them is good. I run my own server (probably obvious being on this list) and can install webmail clients as well. I ran squirrelmail for a while but although functional it's quite dated. I'm using RoundCube for access away from my systems now but it lacks keyboard shortcut support and trying to click one email after another with a laptop touchpad gets painful fast. Thanks, Jonathan

[Dovecot] Override Quota with post-login scripting problem
by Yorck Koehler 23 Nov '09

23 Nov '09

Hi everyone, I do have the following dovecot-setup: Passdb: PAM (Winbind-auth and pam_mkhomedir-session) Userdb: passwd (NSS-winbind) This validates/creates my users with aid of my running ActiveDirectory. Now the problem: My global quota policy works fine, but I need to override them for some users. I was sucessful within IMAP itself. I use post-login scripting for that. The mail-clients displays the user-quota correctly. But delivery is still a problem, because I'm unable to override the settings there with post-login scripting. Everytime I send messages to such a user, dovecot sends it back with "Quota exceeded (mailbox for user is full)"... My Question: Is it possible to override the lda quota like I can do it within imap ? (I dont want to change my setup to MYSQL DB only for per-user Quota, if its possible to use a simple file with names and quota) This is the post-login script: #quotaperuser.sh #!/bin/sh case "$USER" in "ZAGH-V+username") QUOTA_RULE='*:storage=500M';; "ZAGH-V+test") QUOTA_RULE='*:storage=5000M';; esac exec /usr/local/libexec/dovecot/imap $* My Configuration: {dovecot -n} # 1.2.3: /usr/local/etc/dovecot.conf # OS: Linux 2.6.16.60-0.54.5-smp i686 SUSE Linux Enterprise Server 10 (i586) base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.err info_log_path: /var/log/dovecot.info protocols: imap imaps pop3 ssl_listen: * disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_location: maildir:~/Maildir mail_full_filesystem_access: yes mail_executable(default): /usr/local/bin/quotaperuser.sh mail_executable(imap): /usr/local/bin/quotaperuser.sh mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota expire mail_plugins(imap): quota imap_quota expire mail_plugins(pop3): quota expire mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %v.%u lda: postmaster_address: postmaster(a)zag.de mail_plugins: sieve quota expire mail_plugin_dir: /usr/local/lib/dovecot/lda quota_full_tempfail: no deliver_log_format: msgid=%m subject=%s from=%f status=%$ auth default: username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@+ username_format: zagh-v+%u failure_delay: 0 passdb: driver: pam args: session=yes dovecot userdb: driver: passwd plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/sieve quota: maildir:Quota quota_rule: *:storage=100M quota_rule2: Trash:storage=100M quota_warning: storage=90%% /usr/local/bin/quota-warning.sh 90 quota_warning2: storage=75%% /usr/local/bin/quota-warning.sh 75 expire: trash 7 expire_dict: proxy::expire

[Dovecot] v1.2.8 released
by Timo Sirainen 23 Nov '09

23 Nov '09

http://dovecot.org/releases/1.2/dovecot-1.2.8.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.8.tar.gz.sig This is mainly to fix the 0777 base_dir creation issue, which could be considered a security hole, exploitable by local users. An attacker could for example replace Dovecot's auth socket and log in as other users. Gaining root privileges isn't possible though. This affects only v1.2 users, v1.1 and older versions were creating the directory with 0755 permission. If your Dovecot's base_dir isn't in /var/run/dovecot/, you should also make sure that the $prefix/var/ and $prefix/var/run/ (i.e. /usr/local/var/, /usr/local/var/run/ by default) aren't 0777. * Dovecot v1.2.x had been creating base_dir (and its parents if necessary) with 0777 permissions. The base_dir's permissions get changed to 0755 automatically at startup, but you may need to chmod the parent directories manually. - acl: If user has rights from more than one group, merge them instead of choosing one group's rights and ignoring others. - virtual: When using a lot of mailboxes, the virtual mailbox's header could have grown over 32 kB and caused "out of memory" crashes. Also over 64 kB headers couldn't even be updated with existing transaction log records. Added a new record type that gets used with >=64 kB headers. Older Dovecot versions don't understand this header and will log errors if they see it. - FETCH BODYSTRUCTURE didn't return RFC 2231 "key*" fields correctly

[Dovecot] migrating from Courier
by LuKreme 23 Nov '09

23 Nov '09

I've been running postfix/courier-ssl/MySQL/postfixadmin for years, but since I am in the process of building a new server I decide to reexamine my options. I'm sticking with postfix, but I've decided to move from courier to dovecot because everyone is telling me it's much faster, and I really dislike courier's SASL setup and integration with other services. Of course, I have dozens (but not hundreds) of gigabytes of Courier Maildirs for all the users. Most of the users are in MySQL virtual domains and their mail is stored in a common directory (/usr/local/virtual) and owned by a single system user (vpopmail). I've even hacked together a postfix service to run procmail for the virtual users, though my intention of creating a webface allowing them to muck up their own .procmailrcs never came to fruition. I'm doing my user migration in two steps. First, I will rsync all the mail (and all the user webfiles) to the new server, do any setup/conversion/&c to the data on the new server and make sure everything is working and that passwords are preserved. Then, right before the server goes live I will shutdown mail on the old machine, rsync any new mail (hopefully no more than a couple of hours worth) over, do any conversion, and then fire up the new server. 1) what do I need to do to convert or prepare the courier maildirs for dovecot? 2) is the current setup of virtual users reasonable for dovecot? 2.1) Is there a better option than postfixadmin? 3) some of my users are not in MySQL, but are real system users. Is this going to confuse dovecot (it confuses courier no end). These system users are still using courier and courier maildirs. 4) would it be better to take the server live and THEN move/convert the old mail? 5) anything else obvious that I didn't mention or ask that I should have? The most important thing, of course, is to not lose anyone's email. -- "Two years from now, spam will be solved," -- Bill Gates, January, 2004

[Dovecot] Dovecot and SATA Backend
by Nicolas GRENECHE 23 Nov '09

23 Nov '09

Hi all, I plan to run a dovecot IMAPS and POPS service on our network. We handle about 3 000 mailboxes. I thought first buying a topnotch server (8 cores and 16 Go RAM) with equalogic iSCSI SAN SAS 15K for storage backend. On second though (and after a comprhensive read of dovecot features), I saw in http://wiki.dovecot.org/MailLocation that index files can be created on a separete local filesystem. My question is : for 3000 users, is it possible to have only a SATA backend attached to my topnotch server (to handle bigger mail quotas) by storing index on local hard drives (SAS drives) ? Extra question, what is the better : iSCSI SATA backend or NFS share ? NFS share is more convenient to have a failover server. Thanks for your help.
