[Dovecot] dsync mbox->mdbox: Unexpectedly lost From-line and other issues from a big conversion.
by Axel Thimm 16 Nov '10

16 Nov '10

Hi, I'm trying to convert a 33GB mail store from mbox to compressed mdbox (largest mbox is 2.7GB). The source store is live, e.g. there are mails delivered into it and mails are being read. Actually it is my own mail. :) Although my test runs were very successful I have run into trouble with the first run on the whole store. After fighting a bit around with errors like Error: Trying to open a non-listed mailbox with guid=f59c5b31b8f3df4c70180000e7dd553b I did several reruns in case these errors would be fixed on the next iteration, but my mdbox storage wasn't growing anymore. I decided to restart after removing all old index files from the source store in case I had some corruption somewhere. Since on mbox/maildir index files are completely recreatable this would just slow down thing at the worst. Indeed many of the errors went away, and I managed to convert about 10-20%, but then I hit another array of errors that would persist even after restarting: > $ grep -v Info: dsync2.log.old* > dsync2.log.old1:dsync(user): Error: Next message unexpectedly lost from mbox file /home/user/mail/lists/mplayerhq.hu/ffmpeg-devel at 58706201 (cached) > dsync2.log.old1:dsync(user): Error: read(msg input) failed: Invalid argument > dsync2.log.old1:dsync(user): Error: Next message unexpectedly lost from mbox file /home/user/mail/lists/gnupg.org/gnupg-users at 6507197 (cached) > dsync2.log.old1:dsync(user): Error: Unexpectedly lost From-line from mbox file /home/user/mail/lists/gnupg.org/gnupg-users at 6486645 > dsync2.log.old2:dsync(user): Error: mdbox /home/user/mdbox/mailboxes/lists/mplayerhq.hu/ffmpeg-devel/dbox-Mails: map uid lost for uid 26483 > dsync2.log.old2:dsync(user): Error: msg guid lookup failed: Internal error occurred.

I'd like to spot them and correct them, so I tried let's convert to maildir first, which I can debug more easily. Unfortunatly the conversion speed to maildir is about 25 times slower than converting to mdbox (wow!), and it would take almost 5 days to convert to maildir. This is no sane timeframe for debugging, so I'd rather try different tactics with mdbox. One thing I'm going to try is to do an offline conversion of a snapshot of the store. Anyway I wanted to document the issues I saw in case it is something that is a bug in dovecot. -- http://thimm.gr/ - http://ATrpms.net/

[Dovecot] POP users complaining about multiple copies of mail
by H. Wade Minter 16 Nov '10

16 Nov '10

Hello, We just switched from UW to Dovecot for our mail server. The transition went smoothly, except we have some users complaining about their email clients re-downloading mail or getting multiple copies of emails. When we go into their accounts, we only see one copy of the email, so I'm assuming there's something odd in the communication between their client and us that's causing the mail to get downloaded repeatedly. The clients that we've heard about are Outlook and one called "Goldmine". Has anyone run across this before? Scanning the archives didn't show me anything. This is Dovecot 1.2.12-1ubuntu8 on Ubuntu 10.10.

[Dovecot] Trying to building a customized auth plugin
by Antonio Perez-Aranda 16 Nov '10

16 Nov '10

I'm on dovecot 2.0.7 and I trying to building a customized auth plugin. I take passdb-passwd-file.c and userdb-passwd-file.c to try to build with a simple gcc comand out of dovecot environment as in example: export DOVECOT=/path/to/untar/dovecot-2.0.7 gcc -fPIC -shared -g -Wall -I$DOVECOT \ -I$DOVECOT/src/lib \ -I$DOVECOT/src/lib-auth \ -I$DOVECOT/src/lib-sql \ -I$DOVECOT/src/lib-settings \ -I$DOVECOT/src/lib-ntlm \ -I$DOVECOT/src/lib-master \ -I$DOVECOT/src/auth \ passdb-passwd-file.c -o passdb-passwd-file.o With this, I get errors relate with uoff_t Is possible to build this plugin by this way? Another way is patching against one plugin on dovecot RPM, but I prefer this on a separated RPM.

[Dovecot] Single-instance storage is bad for you!
by Daniel L. Miller 16 Nov '10

16 Nov '10

This single-instance storage is going to encourage bad habits! I just found myself preparing an e-mail that needs to be sent to multiple recipients - including several within my own organization - yet it's not necessary for everyone (in-house) to get the large attachment. As I was getting ready to split the message into two parts for distribution I remembered - I can just send it to EVERYBODY in-house and it only occupies a single instance - which it would anyway just being in my "sent" folder! Blasting away... You're quite the enabler, Timo! Now any mail admin who tries to lecture users on only sending attachments to those in-house personnel who really need it, because otherwise it's wasteful of precious server storage space, is going to hear the response, "Dude - don't stress out so much - just setup Dovecot with SIS!". Thanks again! -- Daniel

[Dovecot] service_count=0 for imap and pop3
by Mark Moseley 16 Nov '10

16 Nov '10

This is copy-pasted from Timo's comment in the "Todays Performance Data for 2.0.x" thread, but I didn't want to hijack that thread. In it, Timo says: <snip> service imap { service_count = 0 } (i.e. reuse imap processes) reduced the system CPU usage to almost nothing. But if you use different UIDs for different users you can't do that. </snip> Is that safe to do in imap and/or pop3? Or at least no more insecure than using service_count=0 for imap-login and pop3-login? Since I saw that comment I've been googling around and grepping the wiki but I can only find instances of using it with "service imap-login", not "service imap" or "service pop3". The mention in Timo's comment that it reduces the CPU usage by a lot got my attention, esp for pop3. We're already using service_count=0 for pop3-login and imap-login.

[Dovecot] Local node indexes in a cluster backend with GFS2
by Aliet Santiesteban Sifontes 15 Nov '10

15 Nov '10

Hi, all this days I'm testing a dovecot setup using lvs, director and a cluster email backend with two nodes using rhel5 and gfs2. In the two nodes of the email backend I configured mail location this way: mail_location = sdbox:/var/vmail/%d/%3n/%n/sdbox:INDEX=/var/indexes/%d/%3n/%n /var/vmail is shared clustered filesystem with GFS2 shared by node1 and node2 /var/indexes is a local filesystem at the node, so each node has his own /var/indexes stuff on ext3 and raid1 for improving performance, I mean each node a different /var/indexes of its own. Now, if the director was using node2 for the email for user1 and I removed node2 now all the connections for that user are redirected to node1, that node has its local /var/indexes, when this ocurr I can not see the emails that in fact are in the mailboxes, I guess should be indexes not current with the user mails. Is supposed indexes to be rebuilt automatically when the node switches?? Or I have to configure the indexes in the shared storage so the two node update the information concurrently? I will appreciate your help... best regards

[Dovecot] Is Dovecot Director stable for production??
by Aliet Santiesteban Sifontes 14 Nov '10

14 Nov '10

Today I will try Dovecot Director for a setup using a Cluster Backend with GFS2 on rhel5, my question is if is Director stable for use in production for large sites, I know is mainly designed for NFS but I believe it will do the job also for a cluster filesystem like GFS2 and should solve the mail persistence problem with a node and locking issues. I plan to add a layer behind a load balancer to do the stuff, I will appreciate if you guys can point me to best practices in configuring the director, or how the thing works since is new for me, I have seen the example conf but I don't have clarity in some of the concepts and the wiki is empty. I use 2.0.6, thank's for a great job with dovecot. best regards, Aliet

[Dovecot] Daemon will not start, invalid argument in stat of base_dir (error within)
by Frank Collette 13 Nov '10

13 Nov '10

Running CentOS 5 and Dovecot 1.2.16 Receiving error: Error: stat(/var/run/dovecot) failed: Invalid argument Fatal: Invalid configuration in /etc/dovecot.conf I've put the default dovecot.conf in place and still get the same thing. I've tried removing the /var/run/dovecot folder and letting it re-create it with no success. It creates the /var/run/dovecot folder but that is all. I've tried setting the base_dir to /tmp/dovecot to test and get the exact same error. I'm at a loss as are many other people so am hoping someone here might be able to help!

[Dovecot] dovecot sieve enotify question
by Robert Schetterer 13 Nov '10

13 Nov '10

Hi, sorry not dovecot but heres the question is it possible to use dovecot sieve enotify not only for notify mail i.e arrived but with add the incomming mail as attachment to the notification ? i.e. i have found a example require ["enotify", "fileinto", "variables"]; if header :contains "X-Spam-Flag" "YES" { set "from_addr" "admin(a)example.com"; set "subject" "Spam"; notify :message "${from_addr}: ${subject}" "mailto:user@example.com"; } is there a way to add the orginal mail as attach to the notfication mail , and finally perhaps delete it this would like a redirect/forward with right from_addr ( which should always be the default mailboxname/emailaddress -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] squirrelmail inbox empty
by Paul Cartwright 13 Nov '10

13 Nov '10

I am running Dovecot + Postfix +Squirrelmail on Debian Lenny.Fetchmail pulls the mail, dovecot spreads it around. I had squirrelmail setup & I tested it from within my router ( internal LAN). yesterday I had to go babysit my grand daughter, and I setup port forward for IMAP port 143, and I can use squirrelmail through firefox on my laptop. All the other folders have all the mail from the time I left til now. Yesterday I was reading inbpox mail, deleted a few junks, etc, and suspended my laptop. When I came back my inbox was empty, and I've never seen any more messages in it. I know I should have LOTS of older+new messages that don't get filtered. Unfortunately ssh doesn't seem to work from this linux side, it does from the windos side ( ssh keys?), so I can't get in to look at the logs.. I already removed ( I think ) all the inbox index files... & restarted, but no joy. I am not sure if it is getting filtered from the ibox, or if I just can't see it. I am not familiar with how squirrelmail works with local IMAP folders, so I am unsure where to look or what logs to browse. I will be home later today. suggestions clues or otherwise?? -- Paul Cartwright

[Dovecot] Occasional fchown errors?
by Knute Johnson 12 Nov '10

12 Nov '10

Hi: I get the occasional error below. Is there something I don't have configured correctly? Or should I just ignore this? It is not always this file, sometimes it is the cache.lock file or the log.newlock file. I have a mail client running on my computer and my phone at the same time, could that have something to do with it?

[Dovecot] questions of how to connect to pop3s

I also need to know how to tell someone how to configure their mail client as the pop3 and smtp server. For example do I say pop.pilotalknet.ldyndns.org and smtp.pilotalknet.dyndns.org? The hostname is: pilotalknet.dyndns.org also is it still possible to check the working of the connection via a telnet connection doing: telnet pilotalknet.dyndns.org:995 or do I have to do something different? what I am achieving with the telnet connection is to ensure the pop server comes up with the greeting from dovecot. Thanks much.

[Dovecot] alternate sendmail binary for sieve redirect OT
by Robert Schetterer 12 Nov '10

12 Nov '10

Hi , this isnt really a dovecot/postfix question in dove lda, there is sendmail_path = someone tried other progs here like mini_sendmail ? http://www.acme.com/software/mini_sendmail/ i.e for using a default from forwarder address when sending redirects by sieve....is a stupid idea? background, some other mail providers use a default sender forwarder mailaddress when redirect this may avoid problems at forwarding with spf etc any other idea to reach this goal, pipe etc? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] correct syntax for multiple ports
by Kilburn Abrahams 12 Nov '10

12 Nov '10

Hi, What is the correct format to specify multple ports in dovecot 2. With dovecot 1.2 listen = *:143 *:6188 worked fine. I cannot find any mention in the wiki2 about the different combinations of listen, address and port parameters and dovecot complains about the combinations I tried. Does not seem to work 1. inet_listener imap { listen = *:143 *:6188 } 2. inet_listener imap { address = *:143 *:6188 } 3. inet_listener imap { port = 143, 6188 or port = 143 6188 } This start dovecot, but roundcube will not connect on port 143, although Thunderbird will connect on 1432 and 6188 listen = *, :: 1. inet_listener imap { port 143 port = 6188 } Regards K

[Dovecot] Phantom email message
by Marc Perkel 12 Nov '10

Got sort of a strange problem on one email account. Everything works fine with Thunderbird/IMAP showing the correct unread message count. But on my DroidX smartphone one of my email accounts always shows one unread message, but I can't bring any unread messages up. It's like there's something there making it think there's a message when there isn't. The email client is K-9 mail Anyone have any ideas?

[Dovecot] --exec-mail
by David Woodhouse 12 Nov '10

12 Nov '10

Most of my IMAP access is achieved by 'ssh $mailhost exec dovecot --exec-mail imap'. I'm testing Dovecot 2.0, and this doesn't seem to work any more — and I can't seem to work out how to make it work. The wiki page at http://wiki2.dovecot.org/Upgrading/2.0 has no mention of it. I looked through the git history to find the commit that broke it and see if I could find the replacement that way, but it was the commit entitled 'Initial commit for v2.0 master rewrite.', and wasn't particularly edifying. Once upon a time in the dim and distant past, I believe I used to run /usr/libexec/dovecot/imap directly. But that doesn't set the environment up correctly, so isn't the right way to do it... is it? -- dwmw2

[Dovecot] setting up Dovecot
by Scott Berry 12 Nov '10

12 Nov '10

Hello there, I am a new user of Dovecot. I am using version 1.2.12. Here is the config file: I attached the dovecot.conf file as a screenshot using dovecot -n because I am blind and haven't quite figured out how to copy from the terminal to Gnome yet. My intentions here are as follows: 1. To allow only pop3s because I want to use ssl for security. 2. I am going to be using fetchmail to grab the mail and give it to dovecot. 3. There will be three people adventually grabbing their mail through pop3s. Another question I have is when you tell someone to configure their mail client through pop3s how does that work as far as the server name meaning like most ISp's have pop.whatever.whatever.? Also I am using a smarthost with postfix to send out the mail through Google how do I tell someone how to configure the smtp server in their mail client such as Isp's such as smtp.whatever.whatever. I am using Windows for two of the clients with Windows Mail on a Vista machine and Windows Mail on a Windows 7 machine and Evolution on a Ubuntu linux machine. Looks to me like everything is copeastetic except for how to log in. The SSL cert file in "/etc/ssl/certs/dovecot.pem" is a bit tricky cause I didn't create the cert so I am not sure of the password but I did try my normal root password. Not sure if that works. Other than this actually Dovecot is quite easy to config.

[Dovecot] Dovecot 2.0.7 Virtual plugin
by Henrique Fernandes 12 Nov '10

12 Nov '10

Well, it seens the virtual plugins is not working correctly or i miss undertood how to configurate it. http://wiki2.dovecot.org/Plugins/Virtual as this wiki says, I should be possible to make an ndeamespace namespace { prefix = virtual/ separator = / location = virtual:~/Maildir/virtual } And in side of ~/Maildir/virtual create virtual folders and inside of those folders create dovecot-vitual. But it does not work. Right if i make this conf, on my imap client it shows a folder called virtual ( the prefix, or whtever i put in there ) and show nothing, only shows something if i create a dovecot-virtual inside of ~/Maildir/virtual/ i would appreciate if someone explain what i am doind wrong. Thanks! my dovecot -n # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian squeeze/sid mail_debug = yes mail_location = maildir:~/TesteEmail/Maildir mail_plugins = " virtual" namespace { inbox = yes location = prefix = separator = / } namespace virtual { location = virtual:~/TesteEmail/virtual/ prefix = virtual/ separator = / } passdb { driver = pam } ssl = no userdb { driver = passwd } protocol imap { mail_plugins = " virtual virtual" } []'sf.rique

[Dovecot] $MAIL environment variable to override mail_location works in v1.2.16 but not in v2.0.7 for /usr/libexec/dovecot/imap
by Giam Teck Choon 11 Nov '10

11 Nov '10

Hi, For the past day, I have been researching about making dovecot to support mailfront (http://untroubled.org/mailfront/) imapfront-auth natively and able to use mailfront imapfront-auth with dovecot imap v1.2.16 without starting any dovecot related services and no /etc/dovecot.conf file is required. More information about this can be read at: http://lists.untroubled.org/?list=bgware&cmd=showthread&month=201011&thread… However, same trick can't be used for dovecot v2.0.7. First error is /etc/dovecot/dovecot.conf must be exists so I just simply touch /etc/dovecot/dovecot.conf with empty content to bypass that error. I noticed v2.0.7 is not using $MAIL environment variable to override mail_location? I have read the following: http://wiki2.dovecot.org/MailLocation Any idea to override mail_location setting? I have tried various setting of environment variables such as below: --------------------8<----------8<----------8<----------8<--------------------- #!/bin/sh # $MAIL, $HOME, $MAILDIR, $MAILBOX are the same in mailfront # imapfront-auth if [ -n "$MAIL" ]; then # make dovecot imap escape colon by replacing single : to :: export MAIL=maildir:`echo $MAIL | sed 's@:@::@g'` fi export USERDB_KEYS="$USERDB_KEYS mail" # For knowing all env. uncomment the below line and # see /tmp/imapd-log.txt # printenv >>/tmp/imapd-log.txt exec "$@" --------------------8<----------8<----------8<----------8<--------------------- The above script is being placed between imapfront-auth and dovecot imap (/usr/libexec/dovecot/imap). Thanks for any kind assistance. Kindest regards, Giam Teck Choon

[Dovecot] dovecot dictionary attacks
by PA 11 Nov '10

Hi, I been using dovecot for awhile and its been solid, however I been having some issues with dictionary attacks. I installed fail2ban and for the most part is working fine. However today I got another spammer relaying through my server. Looking at the logs I see the following dictonary attack from 94.242.206.37 Nov 10 03:04:38 pop dovecot: pop3-login: Disconnected: rip=94.242.206.37, lip=209.213.66.10 Nov 10 03:04:38 pop dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=209.213.66.10 rip=94.242.206.37 resp=<hidden> Nov 10 03:04:38 pop dovecot: auth(default): shadow(aarhus,94.242.206.37): lookup Nov 10 03:04:38 pop dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=209.213.66.10 rip=94.242.206.37 resp=<hidden> Nov 10 03:04:38 pop dovecot: auth(default): shadow(abaft,94.242.206.37): lookup Nov 10 03:04:38 pop dovecot: auth(default): shadow(abaft,94.242.206.37): unknown user Nov 10 03:04:38 pop dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=209.213.66.10 rip=94.242.206.37 resp=<hidden> Nov 10 03:04:38 pop dovecot: auth(default): shadow(aarhus,94.242.206.37): unknown user Nov 10 03:04:38 pop dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=209.213.66.10 rip=94.242.206.37 resp=<hidden> Nov 10 03:04:38 pop dovecot: auth(default): shadow(aaron,94.242.206.37): lookup Nov 10 03:04:38 pop dovecot: auth(default): shadow(aaron,94.242.206.37): unknown user Nov 10 03:04:38 pop dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=209.213.66.10 rip=94.242.206.37 resp=<hidden> Nov 10 03:04:38 pop dovecot: auth(default): shadow(ababa,94.242.206.37): lookup ..... And so on.. Then that ip gets banned by fail2ban [root@pop ~]# grep 94.242.206.37 /var/log/fail2ban.log 2010-11-10 03:04:42,416 fail2ban.actions: WARNING [dovecot] Ban 94.242.206.37 However on my smtp mail server that ip is already sending out all sorts of spam with the sasl username of Paramus.

[Dovecot] dovecot dictionary attacks
by Paul Amaral 11 Nov '10

Hi, I been using dovecot for awhile and its been solid, however I been having some issues with dictionary attacks. I installed fail2ban and for the most part is working fine. However today I got another spammer relaying through my server. Looking at the logs I see the following dictonary attack from 94.242.206.37 Nov 10 03:04:38 pop dovecot: pop3-login: Disconnected: rip=94.242.206.37, lip=209.213.66.10 Nov 10 03:04:38 pop dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=209.213.66.10 rip=94.242.206.37 resp=<hidden> Nov 10 03:04:38 pop dovecot: auth(default): shadow(aarhus,94.242.206.37): lookup Nov 10 03:04:38 pop dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=209.213.66.10 rip=94.242.206.37 resp=<hidden> Nov 10 03:04:38 pop dovecot: auth(default): shadow(abaft,94.242.206.37): lookup Nov 10 03:04:38 pop dovecot: auth(default): shadow(abaft,94.242.206.37): unknown user Nov 10 03:04:38 pop dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=209.213.66.10 rip=94.242.206.37 resp=<hidden> Nov 10 03:04:38 pop dovecot: auth(default): shadow(aarhus,94.242.206.37): unknown user Nov 10 03:04:38 pop dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=209.213.66.10 rip=94.242.206.37 resp=<hidden> Nov 10 03:04:38 pop dovecot: auth(default): shadow(aaron,94.242.206.37): lookup Nov 10 03:04:38 pop dovecot: auth(default): shadow(aaron,94.242.206.37): unknown user Nov 10 03:04:38 pop dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=209.213.66.10 rip=94.242.206.37 resp=<hidden> Nov 10 03:04:38 pop dovecot: auth(default): shadow(ababa,94.242.206.37): lookup .....

[Dovecot] dovecot2.0+ldap auth problems
by Antonio Perez-Aranda 10 Nov '10

10 Nov '10

I'm using a config from dovecot 1.2 adapted to 2.0 After update config, and restart dovecot service: If I do a doveadm user user1 then it is found correctly. If I do a doveadm auth user1 then it is ask for the password user, and it's running correctly. But if I tray to login by telnet using IMAP then I get: . login user1 pass1 Connection closed by foreign host. I can see at logs a Info line with: Internal login failre with auth failed It's very odd that with doveadm runs ok and but not with IMAP.

[Dovecot] Help! LDAP/AD Problem with dovecot
by Christian Fischer 10 Nov '10

10 Nov '10

Hey Folks, i am trying to get Dovecot LDA to work with Active Directory dovecot --version 1.2.9 While using Postfix to deliver mail, dovecot does only imap-Services, passdb is auth bind and userdb is static. NOW i want to use Sieve Scripts. So LDA of dovecot is required. So userdb lookup is required. With use of virtual Mailboxes i have a working postfix setup, which needs to be transferred to dovecot. dovecot-ldap-userdb.conf uris = ldap://192.168.0.42 auth_bind = yes dn = myldapuser@mydomain dnpass = mypass #ldap_version = 3 base = DC=base,DC=com deref = never scope = subtree user_attrs = sAMAccountName=mail=maildir:/home/vmail/%$/.EMAIL, =uidNumer=5000, =gidNumber=5000 user_filter = (&(objectClass=user)(|(sAMAccountName=%u)(mail=%u)(othermailbox=%u))) pass_attrs = sAMAaccountName=user,userPassword=password pass_filter = (&(objectClass=person)(sAMAaccountName=%u)) My errors are: - While logging in with IMAP 2010-11-10 00:32:30 imap-login: Error: Timeout waiting for handshake from auth server. my pid=16293, input bytes=0 - manual execution of deliver -d myuser(a)domain.tld: 010-11-10 00:34:16 deliver(myuser(a)domain.tld): Error: userdb lookup(...): Connecting timed out As i said - postfix works!

[Dovecot] need to block user by IP address (tried denyhosts, xinetd, iptables etc)
by Tom 10 Nov '10

10 Nov '10

Hi, I am kind of restricted to using packaged versions of software due to company policy, and we have f12 on our mail server with dovecot-1.2.15-2.fc12.i686 package. we have recently had some brute force attacks on the pop3 and imapd and this results in many processes being used for login attempts. Our dovecot is hosted on a Virtual Private Server which restricts access to IPTABLEs and also make a limit on the number of processes that can be running So I can't restrict the attackers IP addresses via IPTABLES, as we don't have access to that. I can't really patch dovecot as we are reliant on the distro packages. I spent some time trying to get dovecot to run under xinetd but had no luck, and I read some reports that it was not possible using recent versions. I was hoping some advice on what avenue I should proceed with to automatically block brute force attacks on the dovecot server, (that dont use iptables) Thanks, Tom

[Dovecot] emails getting mangled when dragging from Exchange account to IMAP shared folders
by Scott Goodwin 10 Nov '10

10 Nov '10

I'm having the most frustrating issue, and I'm at a loss for what is happening. I'm not even sure it is with Dovecot, but that's why I'm posting this here... if it isn't a dovecot issue, maybe someone can get me headed in the right direction? I've posted relevant dovecot and config info at the bottom of this post. Here's the scenario: We recently migrated our email from Postfix+Dovecot+Amavis+SA to Exchange (not my choice, unfortunately). Now, users have to use Outlook (as opposed to before, when they could choose between Outlook and Thunderbird), and have the new Exchange account set up, as well as their old IMAP account, which they still use for shared project folders. So, emails come in to Exchange, then they drag the emails from the Exchange mailbox to the shared branch under their IMAP account, and into the appropriate job folder. Emails to one specific user in my organization (let's call him Roy(a)Ocean.org) is having his emails mangled when dragging certain items from his Exchange mailbox to the IMAP account. I can't reproduce the issue with any other user. Also, this only seems to happens with emails from one other specific domain (let's call them tornado.org) So, in summary, user1(a)Tornado.orgsend an email to Roy(a)Ocean.organd Sue(a)Ocean.org. Both drag the email from their Exchange box into any folder (shared or otherwise) in the IMAP tree. Sue's copy makes it in just fine, while Roy's copy gets mangled. Here's the headers of the resultant email after Roy has dragged it into the shared folder: ======================================== From: "User1" <User1(a)tornado.org> To: "Roy", "Sue" References: <B3457C1920D7A2438CCC19EF2A527293372B11(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293372D9A(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933A2C3D(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933A310E(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933A3683(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933A3B97(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933D103B(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933D192F(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933D1B12(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933FD341(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933FD8F8(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933FD9A0(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933FDFDD(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8927(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8B46(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8D76(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8D7A(a)abc027.abc.local> <B3457C1920 ======================================== And here's the email body: ======================================== D7A2438CCC19EF2A5272934C8D95(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8DB6(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8F0D(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935008B5(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293500C27(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935011BC(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293525B1D(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293525D81(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293526139(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293526416(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935524A6(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935524C9(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293589E1C(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935BF6A9(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935E7414(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935E75E2(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935E75E8(a)abc027.abc.local> <B3457C1920 D7A2438CCC19EF2A5272935E75F4(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935E800E(a)abc027.abc.local> Subject: RE: Some Subject Date: Tue, 26 Oct 2010 15:11:01 -0700 Message-ID: <B3457C1920D7A2438CCC19EF2A52729364D0A0(a)abc027.abc.local> MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----=_NextPart_000_0118_01CB7755.52354760" X-Mailer: Microsoft Office Outlook 12.0 Thread-Index: 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 Content-Language: en-us X-OlkEid: C664F3259FA9393D4124CD409B5CAE330696EE82 content-class: urn:content-classes:message This is a multi-part message in MIME format. ------=_NextPart_000_0118_01CB7755.52354760 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit <SNIP> =========================================================================== Obviously, it's breaking the message in the References header, and I've tracked down the following byte sequence at the breaking point: 0D:09:0A:09 ...which is CR,TAB,CR,LF. What puzzles me is why Roy's gets broken here, when the others' do not; they're the exact same email, so you'd think they would all get broken. I can't figure out A) where that byte sequence is coming from (our Exchange server, Tornado.net's exchange server, or one of the two of our external spam filtering service... they use BigFish.com, and we use MxLogic), or B) if that's even the issue. I've rebuilt Roy's entire machine, reconfigured Outlook from scratch, still happening. When he logs onto another machine and sets up his Exchange account on another outlook, it still happens. Our Exchange administrator (I don't have access to Exchange) says there is nothing wrong with his Exchange account, for what it's worth. I don't expect anyone to have the solution here, since there are many variables, and there is other info that would probably be needed. What I DO want is to be pointed in the right direction on how I might track this down. For example, what is the path that this mangled email would take in this case? Even with full logging in Dovecot and postfix, I can't see any info on the path that this email follows in our system, and where it might be getting mangled. Does it actually go through the same path as an email that was actually sent to the IMAP account, or is it different when it is dragged in from another account in the same mail client? Is this more likely a problem with Postfix, or Sieve, or....? (I've disabled Amavis and SA to get them out of the picture, and same problem).

Re: [Dovecot] Todays Performance Data for 2.0.x

Dividing the imap processes's system CPU usage by number of imap processes: imap : 0.478872 of 975 imap : 0.460797 of 1242 imap : 0.409641 of 2482 imap : 0.424035 of 4711 imap : 0.488494 of 6148 imap : 0.56809 of 7031 imap : 0.734864 of 6965 So it's about 0.5 seconds of system CPU per imap login. I also get something like 0.3 seconds of system CPU per imap login on my system. Also setting: service imap { service_count = 0 } (i.e. reuse imap processes) reduced the system CPU usage to almost nothing. But if you use different UIDs for different users you can't do that. So, yeah, looks like the process initialization is wasting time somewhere. I'll look further into it.

[Dovecot] mdbox & trash
by Daniel L. Miller 09 Nov '10

Is there a way I can setup "trash" folders to be stored in a different subdirectory using mdbox? The goal is to provide a way to identify the trash folders for my backup solution (rsync) and avoid copying trash. -- Daniel

[Dovecot] how can I use different LDAP config for LDA and AUTH?
by Zhou, Yan 09 Nov '10

09 Nov '10

Hi there, I am setting up mail client with DoveCot and, at the same time, use Postfix to deliver message to DoveCot via LDA. I want to support having user name "jsmith" on my mail client, and that gets all messages for email address: dovecotdemo@domain. (The user name is different from what is in the email address). In addition, all user & password look up is handled by LDAP. Here is my problem: 1. my mail client will login as "jsmith", that goes through LDAP to find mail/home/password for this user. (this matches user name) 2. When postfix delivers a message, DoveCot LDA will find a match with email address "dovecotdemo@domain", it goes through the same LDAP configuration. (this matches email address). You can see the two search criteria are different, but by default they use the same passdb and userdb configuration. I want to use a different LDAP config. file for LDA to use, where it will match the email address (so that it is different from the default dovecot-ldap.conf, which is used by authentication). DoveCot Deliver can specify a separate configuration file with "-c", so I tried that. But I cannot get LDA to use a different configuration. Would should be an example of config file used by Deliver? Anyone running into this problem? Thanks, Yan NOTICE: This email message is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

[Dovecot] 2.0, hourly performance stats
by Ralf Hildebrandt 08 Nov '10

I'm getting constantly high numbers of page reclaims & involuntary context switches for dovecot/auth. page reclaims = minor faults = cpu switching back to system-mode, But why is the auth process doing that so excessively? Same for the large number of involuntary context switches... Attached is my "dovecot -n" output.

[Dovecot] Expunge -A cannot find users
by Kilburn Abrahams 08 Nov '10

08 Nov '10

Hi List, If I use doveadm expunge in this format expunge will delete the email doveadm expunge -u test(a)planetseafood.com mailbox Archive ON '8-Nov-2010' But in this format doveadm expunge -A mailbox Archive ON '8-Nov-2010', it will list all the users in the database and display the following and no messages are expunged. doveadm(test@planetseafood.com@planetseafood.com): Info: User no longer exists, skipping. The iterate_query = SELECT username AS username, domain FROM mailbox which is correct for the DB layout. I am not using the expire plugin. Is this a permissions issue? Thanks Kilburn
