[Dovecot] Ignore leave on server
by Hr. Daniel Mikkelsen 17 Oct '06

17 Oct '06

Hi. Is it possible to ignore "leave on server" for POP3 clients? That is, always delete all downloaded mail automatically? -- Daniel Mikkelsen Copyleft Software AS

[Dovecot] MBox path
by Rick 17 Oct '06

17 Oct '06

Hi, I'm having great difficulty pointing Dovecot to my MBox files. They are all in /var/spool/mail/username as textfiles.. not directories. So my guess was: default_mail_env = /var/spool/mail/%u Since %u is user. If the user is "server" I would expect it to go to /var/spool/mail/server exactly what I want. But it doesn't /var/spool/mail///home/server. If I create the directory home in /var/spool/mail and make a symlink of the username pointing to /var/spool/mail it does work. But that's a very dirty workaround I rather not use, also because we have a lot of users.. a lot of symlinks. If I set default_mail_env = /var/spool/mail, it also searches for /var/spool/mail///home/server. I feel like I've tried everything. What am I doing wrong? I'm using version 1.0.beta8, included in Fedora Core 5. Thanks, Rick

[Dovecot] Dovecot still failing with RC10...
by Timothy Meader 16 Oct '06

16 Oct '06

Hello, I mentioned back with version RC8 that dovecot was having an issue with the first login working, but all subsequent attempts failing with the error message: "Error: Maximum number of mail processes exceeded" in the dovecot log file. This is with an unchanged working conf file from RC7 (which, aside from comments, nothing has changed config-wise in the conf from version RC7). Now, the max mail processes were already set at 1024 (and I'm the only person using this server while testing), but just for the heck of it, I tried bumping the number up to 4096 and giving it another shot. No such luck. You can login once, but any subsequent attempts come back with the error I mentioned. This is making all versions above RC7 unusable for me unfortunately. I was hoping to get buy-off on switching from QPopper/UWImap to an all Dovecot solution with the pending 1.0 final, but I doubt they'll go for allow and RC being run on the production side. Two notes that might help(?): -I'm running this on Solaris 9, not a Linux box -Dovecot is not running in daemon mode, it's running through xinetd Here are the xinetd.conf sections that are relevant: defaults { #The maximum number of requests a particular service may handle # at once. instances = UNLIMITED # The type of logging. This logs to a file that is specified. # Another option is: SYSLOG syslog_facility [syslog_level] log_type = FILE /var/log/servicelog # What to log when the connection succeeds. # PID logs the pid of the server processing the request. # HOST logs the remote host's ip address. # USERID logs the remote user (using RFC 1413) # EXIT logs the exit status of the server. # DURATION logs the duration of the session. log_on_success = HOST PID DURATION EXIT # What to log when the connection fails.

[Dovecot] indexes?
by David Lee 16 Oct '06

16 Oct '06

Picture: A set of very similar UN*X IMAP servers all NFS-mounting their INBOX area (traditional Unix format) from a common "/var/spool/mail" area; activity for any given user ought to be within one box although this cannot be 100% guaranteed. There is the risk of multiple simultaneous access (e.g. simultaneous LDA/delivers; simultaneous LDA/deliver and user-driven IMAP update; etc.). So locking is an important consideration. Decent "noac,actimeo=0" seems to address this succcessfully. But indexes... What is the best place for the index files? Logically alongside the INBOX area on the shared-NFS area? Or within each UN*X machine? (Or something else?) And why? Is there documentation of what functionality the index files provide, and how, if at all, this interacts with the locking of INBOXes (and folders). Thanks. -- : David Lee I.T.

[Dovecot] quota dict (mysql)
by Peter Veerman 16 Oct '06

Hi, I have dovecot configured to make use of the dict (mysql) plugin in order to keep track of the used quota. First, as you can see in the mysql table output below it seems that values aren't stored correctly. Secondly I get all kinds of database related errors in my mail logs. The (relevant) sections of the configuration files are also included below. My question is, what am I doing wrong?

[Dovecot] System-wide sieve script?
by Ty! Boyack 16 Oct '06

16 Oct '06

In the dovecot LDA documentation, it mentions having sieve scripts located in ~/.dovecot.sieve, which works great for per-user sieve code. I was trying to find out if there was a system-wide sieve script (maybe /etc/dovecot.sieve?) that would hopefully be run first, followed by any per-user sieve code. Anyone know if this is already possible, or if not, if there are any plans to implement this? I'm assuming one could make a kludgey fix by having every .dovecot.sieve include a system-wide file, but that would allow a user to remove that "include" if they choose. I'd like to have a centrally controlled, immutable set of rules that all mail goes through. If I missed something in the wiki or archives, I offer my apologies in advance. Thanks! -Ty!

[Dovecot] LDAP Memory Leak
by Daniel 16 Oct '06

16 Oct '06

Hi Timo I use LDAP auth on a system with around 2000 email account. I use dual OpenLDAP servers. I haven't noticed a leak of memory. Is there any more information and I will have a look to see if I can see anything that might help. Is it only affecting certain machines or all? Regards Daniel Rowe Date: Mon, 16 Oct 2006 02:39:26 +0300 From: Timo Sirainen <tss(a)iki.fi> Subject: [Dovecot] 1.0.rc10 released To: dovecot-news(a)dovecot.org, dovecot(a)dovecot.org Message-ID: <1160955566.5448.126.camel@hurina> Content-Type: text/plain; charset="us-ascii" http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz.sig I've finally read all the mails in the mailing list and in my INBOX. If I haven't replied to some of your mail, please resend it. Remember that since 1.0.rc9 release dovecot.index.cache files will get rebuilt in 64bit systems, and it's probably better to delete them manually so you don't get errors in log files.

[Dovecot] Dovecot and CRAM-MD5 authentication (brief) HOWTO
by James Turnbull 16 Oct '06

16 Oct '06

Hi all, I just finished configuring CRAM-MD5 for Dovecot and noted there were not a lot of resources out there that described the process. I've written up a rough and brief HOWTO at: http://www.kartar.net/weblog/cram-md5-authentication-with-dovecot/ Comments welcome and hope it helps someone.

[Dovecot] LDAP Memory Leak
by Daniel 16 Oct '06

16 Oct '06

Hi Timo I use LDAP auth on a system with around 2000 email account. I use dual OpenLDAP servers. I haven't noticed a leak of memory. Is there any more information and I will have a look to see if I can see anything that might help. Is it only affecting certain machines or all?

[Dovecot] Apple Mail quota display
by Timothy Martin 16 Oct '06

16 Oct '06

I know this isn't necessarily a dovecot issue, but I was wondering if anyone has the quota displaying correctly in Apple Mail? I have it set up and working and displaying properly in thunderbird, roundcube (webmail), and squirrelmail. But for some reason Apple's Mail doesn't show the values or its nice thermometer bar. Are there additional configuration options for quota not documented on the wiki? .tim

[Dovecot] Duplicate mails
by Vegar Nilsen 16 Oct '06

16 Oct '06

Hi, one of our customers reported a problem after we moved her maildir to another disk. (Jail in FreeBSD 6, moved to another disk with rsync.) For some reason she's seeing duplicates of almost every message from November, 2005 until June, 2006 (the move happened in September, 2006.) It seems like these mails have been respooled somehow and been inserted into the maildir with the same date and time as the original: root#loc [</var/gopostal/maildirs/wow/lina/cur>] diff 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac root#loc [</var/gopostal/maildirs/wow/lina/cur>] ls -l 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf -rw------- 1 mailnull mail 7755 Nov 24 2005 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf root#loc [</var/gopostal/maildirs/wow/lina/cur>] ls -l 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac -rw------- 1 mailnull mail 7755 Nov 24 2005 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac As the diff command shows these mails are identical, except that one was created about 10 months after the other. 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac was written by Exim in November (we've configured Exim to add the size (",S=7755") to the file name), but I have no idea where the other file comes from. Could this be Dovecot that has recreated these mails for some reason? (Since the file names are different I doubt that this happened during the rsync, instead it must come from some program that conforms to the maildir standard of naming files. The mailserver had a different name back in November, mail9 was the old name, locusts is the new one.) Originally this file 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf was named 1158863410.P19488Q34M511758.locusts.copyleft.no:2,bf which, if I understand it correctly, means it's unread. (The customer has deleted it since reporting this problem.) root#loc [</var/gopostal/maildirs/wow/lina/cur>] uname -r ; dovecot --version ; exim -bV 6.1-RELEASE 1.0.beta3 Exim version 4.60 #0 (FreeBSD 6.0) built 22-Feb-2006 13:01:52 If anybody has an idea as to what caused this I would really appreciate any pointers or info.

[Dovecot] Authenticating dovecot against Active Directory using bsdauth and login_ldap
by Martin Croker 16 Oct '06

16 Oct '06

All, I'm working in a multi-platform environment where user accounts are already held in Active Directory. I'm been trying to setup dovecot to perform user authentication against Active Directory using ldap. My Environment is: Platform OpenBSD 3.9 Dovecot Version 1.0.rc7 Active Directory Windows 2003 The approach I've taken (being the only one I was able to make work) is to use login_ldap to perform bind authentication against Active Directory/LDAP and authenticate dovecot using bsdauth. As far as I can tell the dovecot ldap authentication module requires access to the encrypted password field to which Active Directory does not permit access. Simulated LDAP login fails and when debug is enabled writes the following to /var/log/maillog ==== /var/log/maillog ================ Oct 15 20:12:27 server dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=***********************== Oct 15 20:12:27 server dovecot: auth(default): bsdauth(mcrokerx,127.0.0.1): invalid password field Oct 15 20:12:28 server dovecot: auth(default): client out: FAIL 1 user=mcrokerx Oct 15 20:12:38 server dovecot: imap-login: Aborted login: user=<mcrokerx>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured ======================================= It appears that the cause of these log messages are the following lines of code in src/auth/passdb-bsdauth.c ==== src/auth/passdb-bsdauth.c ======== 29 if (!IS_VALID_PASSWD(pw->pw_passwd)) { 30 auth_request_log_info(request, "bsdauth", 31 "invalid password field"); 32 callback(PASSDB_RESULT_USER_DISABLED, request); 33 return; 34 } ======================================= These lines seem to require that the pw structure contains the encrypted password in pw->pw_passwd. Where login_ldap is used against Active Directory the encrypted password is not available to bsdauth and instead pw->pw_passwd contains '*'. If auth_userokay is called independently it is however able to authenticate the user correctly, as such I wonder if the IS_VALID_PASSWD check is actually necessary. It could be that my entire approach is wrong in which case I'm happy to be put right; however it seems that lines 29-34 need modification to correctly support this behaviour of bsdauth. This is beyond my limited ability in c but temporarily removing these lines of code from passdb-bsdauth.c has enabled me to authenticate dovecot against login_ldap (and thereby against Active Directory). My config files are: ==== /etc/dovecot.conf ================ base_dir = /var/dovecot/ ssl_cert_file = /etc/ssl/certs/server.crt ssl_key_file = /etc/ssl/private/server.key disable_plaintext_auth = no login_dir = /var/dovecot/login login_user = _dovecot mmap_no_write = yes protocol imap { imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth default { mechanisms = plain passdb bsdauth { } userdb passwd-file { args = /etc/passwd } user = root } plugin { } ======================================= ==== /etc/login.conf (exert) ========== staff:\ :auth=-ldap:\ :x-ldap-server=10.0.0.23:\ :x-ldap-port=389:\ :x-ldap-noreferrals:\ :x-ldap-uscope=subtree:\ :x-ldap-basedn=dc=my,dc=domain,dc=co,dc=uk:\ :x-ldap-binddn=cn=UnixUser,cn=Users,dc=my,dc=domain,dc=co,dc=uk:\ :x-ldap-bindpw=mypassword:\ :x-ldap-filter=(&(objectClass=user)(mail=%u)):\ :datasize-cur=512M:\ :datasize-max=infinity:\ :maxproc-max=256:\ :maxproc-cur=128:\ :requirehome@:\ :tc=default: ======================================= Note: for login_ldap to work it is necessary that the user information (minus password) is replicated on the localhost. I've done this using a relatively inelegant script which for completeness is below. I guess adding some error checking would be a good idea. ==== ldapsync.ksh ===================== #!/bin/ksh ldapsearch -h 10.0.0.23 \ -D cn=UnixUser,cn=Users,dc=my,dc=domain,dc=co,dc=uk \ -b cn=Users,dc=my,dc=domain,dc=co,dc=uk \ -w mypassword \ -v \ -x "(objectClass=user)" | while read key value ; do if [ "$key" == name: ]; then ldap_name="$value" fi # User Mail field as Unix name - remove @my.domain.co.uk if necessary if [ "$key" == mail: ]; then ldap_mail=$( echo "$value" | sed 's/@.*//g' ) if ( id 2>/dev/null >/dev/null $ldap_mail ); then usermod -c "$ldap_name" -s osbin/nologin -g staff -L staff $ldap_mail else useradd -d /home/$ldap_mail -c "$ldap_name" -s /sbin/nologin -m -g staff -L staff $ldap_mail fi ldap_name="" ldap_mail="" fi done ======================================= Martin

[Dovecot] Messages not expunged
by Jackie Hunt 16 Oct '06

16 Oct '06

Hi all, I'm doing some testing between U of Washington IMAP server (which we currently run) and Dovecot on a IBM AIX system. I created a 50M mailbox, made up of 262 msgs. I'm using a Perl Script with the imap::client module to fetch each message and then flag it for deletion. At the end of the test, I run an expunge to delete all the messages. UofW imap server ran fine, messages gone. With dovecot I found the messages were not being expunged. The log indicated they were, but then said 262 messages existed at the end. After more checking, I found the file system I was using was low on disk space (<50M). As soon as I added more disk space, and reran the test with dovecot the messages were indeed expunged. Is this normal imap protocol behavior? I thought I would see an error message or something in the dovecot log. Does dovecot duplicate the mailbox before expunge? There wasn't room on our system to do that. Thanks much for any insights/info.

[Dovecot] Restricting Services (POP or IMAP)
by Odhiambo WASHINGTON 15 Oct '06

15 Oct '06

It would be great to have a HOWTO in the wiki, on how to restrict services by username in dovecot, so some users are allowed IMAP and others not allowed. As concerns restricting users by IP, I believe that is a bad idea. It's almost a useless idea, imnsho, because they can connect from another IP. It's easy to restrict services by IP using a firewall or by using inetd. -Wash http://www.netmeister.org/news/learn2quote.html DISCLAIMER: See http://www.wananchi.com/bms/terms.php -- +======================================================================+ |\ _,,,---,,_ | Odhiambo Washington <wash(a)wananchi.com> Zzz /,`.-'`' -. ;-;;,_ | Wananchi Online Ltd. www.wananchi.com |,4- ) )-,_. ,\ ( `'-'| Tel: +254 20 313985-9 +254 20 313922 '---''(_/--' `-'\_) | GSM: +254 722 743223 +254 733 744121 +======================================================================+ Don't take life too seriously -- you'll never get out of it alive.

[Dovecot] Dovecot rc9 error (More information)
by Daniel 15 Oct '06

15 Oct '06

Hi This happens when email is copied/moved from the inbox to another folder on the same imap account. The mail client goes into a loop with the below errors logged. This is on a 64bit Linux machine using the Maildir storage format. After doing a 'rm dovecot*' from the Maildir folder of the account having the problem the client can log in again but if the client tries to copy again it gets the same error. RC9 appears to be broken on this box. I have tested connecting form a windows machine and I get the same with thunderbird. I have tried with different accounts and they get the same problem. I have down graded to RC8 and all is working OK so seems to be a problem introduced with RC9. I have a 32bit Linux server with RC9 installed which has around 2000 accounts on it and this has no problems so maybe not affecting 32bit machines. If I can give any more information please let me know. Am getting this error with Dovecot rc9 on a imap account.
