[Dovecot] Dovecot ACL
by Barry Kwok 15 Feb '07

15 Feb '07

I am using 1.0-rc19 version. I made a global ACL file in /etc/dovecot-acls/Public as: owner lrsi user=manager rl The owner cannot delete/move mail inside his Public folder as I want. But the user "manager" cannot subscribe/view to other's Public folder. What I have missed?

[Dovecot] lda sieve broken after upgrade
by lenny＠edpausa.com 15 Feb '07

15 Feb '07

upgraded to rc19. using maildirs. solaris 9/cc. removed all modules from pop/imap/lda subdirs and first upgraded dovecot to rc19 and then used dovecot-sieve-1.0.1 sources to build against the dovecot source directory ( everything now builds nicely on Solaris, thank you Timo ). added "cmusieve" to the list of plugins used by lda. ail_plugins = cmusieve now getting this: deliver(lenny): Error: dlopen(/usr/local/dovecot/lib/dovecot/lda//lib90_cmusieve_plugin.so) failed: ld.so.1: deliver: fatal: relocation error: file /usr/local/dovecot/lib/dovecot/lda//lib90_cmusieve_plugin.so: symbol deliver_mail: referenced symbol not found anyone ? on the same machine, mbox based dovecot rc19 with dovecot ( sieve ) lda, works and upgraded without any issues, although the prior version must have been different, since the cmusieve statement was already present.

by Vikram Goyal 15 Feb '07

15 Feb '07

Hello Guys! I have just joined the list as I needed some clarifications, help etc. I am not sure what I want is possible and I have been unable to do it myself, read lots of dovecot wiki pages, debian lists, dovecot archives, experimented myself and so on. I have a mail dir ~/Mail where all my mails get distributed to their respective folders through procmail filters. The heirarchy is as follows: ~/Mail/ /inbox --> maildir /trash --> trash maildir /newsletter --> mbox lists/ --> normal dir /dovecot --> dovecot list maildir /some other list maildirs I wanted to access them through dovecot. I have tried namespaces etc but have been unable to accomplish till now. Kindly help. Thanks! -- vikram... |||||||| |||||||| ^^'''''^^||root||^^^'''''''^^ // \\ )) //(( \\// \\ // /\\ || \\ || / )) (( \\ -- o ~|~ = Registered Linux User #285795

[Dovecot] auto-detection of user mailbox type - followup

In http://www.dovecot.org/list/dovecot/2006-December/018253.html Timo Sirainen wrote > > You can still change NAMESPACE_* environments. I don't remember how > exactly now, but you can do eg. "set > /tmp/sets" in the script, see > what it has set and modify them in the script. in response to my query regarding setting the mail_location in namespaces from a mail_executable script. The purpose of this is to be able to select on a per-user basis whether they're using Maildir or mbox format (I don't want to convert 12000 users all at once, and some users have no need or desire to change formats - they still use mail/elm etc) and also have the UW-IMAP compatibility namespaces to take care of all the clients currently configured with imap server directory = mail/. This all works, with one small bug left. For reference, here's the gist: In the dovecot.conf file place the usual namespace directives following the Namespaces wiki: namespace private { separator = / prefix = inbox = yes } #for UW backwards compatibility: namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } namespace private { separator = / prefix = ~%u/mail/ hidden = yes } define the mail_executable under protocol imap: mail_executable = /usr/local/dovecot/lbin/imap.sh and write the imap.sh script: ------start imap.sh--------------------------------------------------- #!/bin/sh # determine if user is in mbox or Maildir mode # Maildir takes precedence and is identified by the existence of # both a .procmailrc recipe and the Maildir directory. # Without a .procmailrc file, there's no recipe to force delivery in # Maildir format, so any existing Maildir is spurious # The .procmailrc should contain DEFAULT=Maildir/ # Set the absolute path to this script as the mail_executable for # the imap protocol in dovecot.conf. # It appears that this script is run as the user in their home dir if [ -f .procmailrc -a -d Maildir ]; then MAIL='maildir:~/Maildir'; export MAIL else MAIL='mbox:~/mail:INBOX=~/.mail'; export MAIL fi # each namespace defined in the conf file needs to have the mail # location defined which is set in environment vars # NAMESPACE_1 etc NAMESPACE_1=$MAIL; export NAMESPACE_1 NAMESPACE_2=$MAIL; export NAMESPACE_2 NAMESPACE_3=$MAIL; export NAMESPACE_3 NAMESPACE_4=$MAIL; export NAMESPACE_4 #debugging to see what else we can play with #set >> /tmp/d exec /usr/local/dovecot/libexec/dovecot/imap ------end imap.sh----------------------------------------------------- However, it appears that the root dir '~/mail' string is used at some point before the tilde-expansion takes place. I see a literal ~ directory in the users home, with an empty mail directory inside. After that it picks up the proper location and works correctly. I tried a %h and got a literal %h directory. So for now I made a simple workaround by using the absolute path to the home directory: # use home variable (depends on this script running in users home) # During startup it seems like ~/mail is interpreted as a string and # a spurious ~ folder is created, before the ~ is expanded home=`/bin/pwd` if [ -f .procmailrc -a -d Maildir ]; then MAIL="maildir:$home/Maildir"; export MAIL else MAIL="mbox:$home/mail:INBOX=$home/.mail"; export MAIL fi Thanks, John Harper ------------------------------------------------- Senior Systems Administrator Information and Instructional Technology Services University of Toronto Scarborough harper(a)utsc.utoronto.ca

[Dovecot] dovecot and libnss-ldap
by Nicolas Boullis 15 Feb '07

15 Feb '07

Hi, I've been using dovecot 0.99.14 for a few years, with libpam-ldap and libnss-ldap, and never experienced any problem with those. I expect to soon switch to dovecot 1.0rc15 (or whatever gets available in Debian Etch, hopefuly dovecot 1.0), but I've seen some warnings against dovecot+libnss-ldap... Is the problem with libnss-ldap a recent problem (I mean it was not a problem with older dovecot such as my 0.99.14)? Is it still a problem even with 1.0rc22? Is there any hope to have it fixed before 1.0? Note that while most of the users I have to deal with are in my LDAP directory, a few ones are not and are in /etc/passwd. Hence, "userdb ldap" is probably not an option for me (and I'm quite happy with configuring all my servers with PAM and NSS). Cheers, Nicolas

[Dovecot] DoveCot compression to save HDD space
by Host Expert 15 Feb '07

15 Feb '07

Hello, I am wondering if there are any possibilities to save HDD space used by emails by compressing content (not just attachements). It would be many 1000s email boxes and probably each using lot of space so would be easier if we can just compress emails somehow. Thanks, Cristian

[Dovecot] Last login fields
by Dean Manners 15 Feb '07

15 Feb '07

Hey guys, Wondering if anyone has tried to do this before - a last login timestamp field. Using mysql for auth, I figured it would be easy enough to add a timestamp field and then tack an UPDATE statement on the end of the password_query. But of course, dovecot sees this as only one statement to pass to MySQL - of which MySQL barfs at.. Any ideas on how to achieve this ? Regards __________________________________________ Dean Manners

[Dovecot] Dovecot not responding
by Andrew Hoag 15 Feb '07

15 Feb '07

Hi all, I'm pulling my hair out on this problem and wanted to throw it out there to see if anyone else had run across it. I recently restarted my server. There were some network config issues that caused the interfaces not to come back up, but my colo company got those resolved. However, after restart, my IMAPS server has stopped responding to outside requests. I can successfully access IMAP from localhost, as well as via SSH tunnelling, so I know it is working. I've tried all sorts of "listen=" configurations, and checked lsof & tcpdump to rule out other problems, but it just seems as though dovecot isn't responding. TCPDUMP (notice the TCP SYN but no response): /var/log 89# tcpdump -vvs 192 port 993 tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 192 bytes 17:37:54.101518 IP (tos 0x0, ttl 112, id 56543, offset 0, flags [DF], length: 48) c-24-9-151-115.hsd1.co.comcast.net.3132 > mail.server.com.imaps: S [tcp sum ok] 1828791628:1828791628(0) win 16384 <mss 1460,nop,nop,sackOK> 17:37:58.282840 IP (tos 0x0, ttl 59, id 54721, offset 0, flags [DF], length: 60) dsl001-148-165.sfo1.dsl.speakeasy.net.39250 > mail.server.com.imaps: S [tcp sum ok] 3827175783:3827175783(0) win 5840 <mss 1460,sackOK,timestamp 1555809446 0,nop,wscale 2> 17:38:00.130267 IP (tos 0x0, ttl 112, id 56548, offset 0, flags [DF], length: 48) c-24-9-151-115.hsd1.co.comcast.net.3132 > mail.server.com.imaps: S [tcp sum ok] 1828791628:1828791628(0) win 16384 <mss 1460,nop,nop,sackOK> 17:38:01.283013 IP (tos 0x0, ttl 59, id 54722, offset 0, flags [DF], length: 60) dsl001-148-165.sfo1.dsl.speakeasy.net.39250 > mail.server.com.imaps: S [tcp sum ok] 3827175783:3827175783(0) win 5840 <mss 1460,sackOK,timestamp 1555810196 0,nop,wscale 2> LSOF: /var/log 91# lsof -i | grep imap sshd 4475 andrew 11u IPv4 39601 TCP localhost:34661->localhost:imaps (ESTABLISHED) dovecot 6540 root 5u IPv4 38988 TCP *:imaps (LISTEN) imap-logi 6599 dovecot 9u IPv4 39602 TCP localhost:imaps->localhost:34661 (ESTABLISHED) imap-logi 6629 dovecot 1u IPv4 38988 TCP *:imaps (LISTEN) imap-logi 6630 dovecot 1u IPv4 38988 TCP *:imaps (LISTEN) NETSTAT: /var/log 92# netstat -an | grep 993 tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:993 127.0.0.1:34661 ESTABLISHED tcp 0 0 127.0.0.1:34661 127.0.0.1:993 ESTABLISHED STRACE: 17:00:33.225030 gettimeofday({1171501233, 225048}, {480, 0}) = 0 17:00:33.225072 gettimeofday({1171501233, 225090}, NULL) = 0 17:00:33.225113 poll([{fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 4, 0) = 0 17:00:33.225163 gettimeofday({1171501233, 225182}, {480, 0}) = 0 17:00:33.225212 gettimeofday({1171501233, 225230}, NULL) = 0 17:00:33.225260 poll([{fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 4, 999) = 0 17:00:34.225145 gettimeofday({1171501234, 225179}, {480, 0}) = 0 17:00:34.225204 gettimeofday({1171501234, 225222}, NULL) = 0 17:00:34.225246 poll([{fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 4, 0) = 0 17:00:34.225297 gettimeofday({1171501234, 225315}, {480, 0}) = 0 Has anyone seen this behavior? What's the obvious thing I'm missing here? My host has some weird VLAN thing installed by the colo company so I have IP aliases, but given I'm not even seeing a response to the SYN, it doesn't seem to be a routing issue, and I can connect to my local interface on port 993 (NOT localhost) without problems. Suggestions much appreciated, I'm stuck. I'm sure this is something obvious and simple, but I'm looking past it right now.
