[Dovecot] you got chocolate in my peanut butter?!
by Logan Shaw 13 Oct '06

13 Oct '06

Hey everyone, Ran into something positively perplexing today. A user came to me and said that this morning when they checked their mail, they got about 120 strange new messages. Upon further inspection, it seems the "new" messages are all addressed to a certain other different user and are all 3 or 4 months old. And looking in that other user's /var/mail/(username) mailbox, I see the same messages that arrived mistakenly. And they're not in the /var/mail mailbox of the user whose desktop computer they ended up on. So it would appear that, possibly, when this user connected to the server, they got someone else's messages! Messages that, in fact, came from an account they don't even have the password to! I'm really curious if anyone has seen something like this before. We're using dovecot-1.0.beta9, and have been since mid-June. I've never seen anything happen like this before. I'm perfectly willing to upgrade to the latest release candidate, but it's hard for me to "upgrade and see if that fixes it", because it happens so rarely and it won't be easy to know empirically. So what I'm really hoping for is confirmation that this is/was a known problem, if in fact it is. Of course, I don't know that this is a dovecot bug, but I could imagine that it might be (maybe a daemon forgets to switch users after one session is closed and another is opened?), so I thought I'd ask. I did see what looked like TLS fixes and login fixes in the changelogs, so it doesn't seem out of the question that such a bug could've existed. Some more information: I checked the user's settings on their desktop computer, where the unexpected messages appear, and sure enough, there is only one POP server account configured there, and it has the correct username. What's more, I asked them what time this happened, and they said probably at 7:00am or maybe a little earlier. Looking at my dovecot logs, I see this (where 'theuser' is the user who received the messages): Sep 28 06:59:49 myhostname dovecot: pop3-login: Disconnected: user=<theuser>, method=PLAIN, rip=192.168.1.245, lip=192.168.1.20, TLS Sep 28 06:59:55 myhostname dovecot: pop3-login: Login: user=<theuser>, method=PLAIN, rip=192.168.1.245, lip=192.168.1.20, TLS Sep 28 06:59:55 myhostname dovecot: POP3(theuser): Disconnected: Logged out top=0/0, retr=0/0, del=0/9, size=130585 So, it would seem that the user did login at the time they claimed and it was at that time (or close to it) that the weird messages appeared. Also, I checked the logs for logins from the person whose messages accidentally got downloaded, and it doesn't show them logging in until several hours later. Oh, and there are no log entries for either of the two users in question before that, at least not for over 12 hours before that. The user is running Outlook 2003, with POP3 + TLS access to the mailbox. My dovecot.conf has nothing fancy in it: base_dir = /var/run/dovecot/ ssl_cert_file = /etc/mail/certs/server.crt ssl_key_file = /etc/mail/certs/server.key protocols = imap imaps pop3 pop3s disable_plaintext_auth = no login_dir = /var/run/dovecot/login syslog_facility = local0 first_valid_uid = 100 protocol imap { } protocol pop3 { pop3_lock_session = yes pop3_uidl_format = %08Xv%08Xu } auth default { mechanisms = plain user = root passdb shadow { } userdb passwd { } } The accounts are all coming out of LDAP via nsswitch (and this is all happening on Slackware 10.2), but I'm fairly sure that's irrelevant since "getent passwd", etc. all show the right stuff. Thanks for any help anyone can give... - Logan

[Dovecot] Feature req: auth_cache_relookup
by Bill Boebel 13 Oct '06

13 Oct '06

With auth_cache_size set to a value greater than zero, when our users change passwords their accounts stop working for a few minutes, because they are trying to log in with their new password, but Dovecot is comparing that against the cached old password. It would be nice if an option could be added so that if the login password does not match the cached password, the cache value is dropped and dovecot-auth queries the userDB, but only if the previous login was successful (to avoid frequent queries for bad logins). Maybe this option could be called "auth_cache_relookup" Bill

[Dovecot] default_mail_env renaming
by Timo Sirainen 13 Oct '06

13 Oct '06

I was thinking about renaming default_mail_env to something that is more understandable. I'll keep it working for backwards compatibility anyway. How about: # Location for users' mailboxes. This is the same as the old default_mail_env # setting. The default is empty, which means that Dovecot tries to find the # mailboxes automatically. This won't work if the user doesn't have any mail # yet, so you should explicitly tell Dovecot the full location. # # If you're using mbox, giving a path to INBOX file (eg. /var/mail/%u) isn't # enough. You'll also need to tell Dovecot where the other mailboxes are and # where Dovecot can place its index files. # # There are a few special variables you can use, eg.: # # %u - username # %n - user part in user@domain, same as %u if there's no domain # %d - domain part in user@domain, empty if there's no domain # %h - home directory # # See doc/variables.txt for full list. Some examples: # # mail_location = maildir:/var/mail/%1u/%u/Maildir # mail_location = mbox:~/mail/:INBOX=/var/mail/%u # mail_location = mbox:/var/mail/%d/%n/:INDEX=/var/indexes/%d/%n # # http://wiki.dovecot.org/MailLocation # #mail_location =

[Dovecot] 1.0.rc8 released
by Timo Sirainen 13 Oct '06

13 Oct '06

I've still over 200 mails unread in the mailing list, and important things left in TODO. This release is an improvement over rc7 anyway, hopefully I'll have time to fix the rest soon. http://dovecot.org/releases/dovecot-1.0.rc8.tar.gz http://dovecot.org/releases/dovecot-1.0.rc8.tar.gz.sig * GSSAPI: Changed POP3 service name to "pop", which is what the standard says * "mbox:/var/mail/%u" no longer works as the mail location. You'll have to specify the mail root explicitly, just like the examples always have: "mbox:~/mail:INBOX=/var/mail/%u" + SHA1, LDAP-MD5, PLAIN-MD5, PLAIN-MD4: The password can be now either hex or base64 encoded. The encoding is detected automatically based on the password string length. + Allow running only Dovecot master and dovecot-auth processes with protocols=none setting + deliver: -f <envelope sender> parameter can be used to set mbox From_-line's sender address + deliver: Log all mail saves and failures + Tru64 SIA passdb support. Patch by Simon L Jackson. - INBOX was listed twice in mailbox list if namespace prefix was used - INBOX-prefixed namespaces were a bit broken - kqueue: Fix 100% CPU usage - deliver: Duplicate storage was a bit broken - dictionary code was broken (ie. dict quota) - SIGHUP caused crashes sometimes

[Dovecot] 1.0rc8: another problem? Possibly 64-bit index?
by David Lee 13 Oct '06

13 Oct '06

Yesterday I gave a status report about 10.rc8 in production, which mentioned a problem about "Login process died too early..." Timo suggested a patch for logging error messages. I've applied this. Others suggested increasing "login_max_processes_count". That was already way above our likely maximum, but I've doubled it anyway. Today, I've just repeated the trial, but with one significant difference and one significant new problem. The significant difference is that today's machine is not a 32-bit i686 but a 64-bit (and faster) x86_64. The new problem is lots of occurences of: [...]: IMAP([...]): file ../../../src/lib-index/mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) [...]: child 4365 (imap) killed with signal 6 and: [...]: IMAP([...]): file ../../../../src/lib-storage/index/index-mail.c: line 105 (index_mail_get_fixed_field): assertion failed: (buffer_get_used_size(buf) == data_size) [...]: child 15009 (imap) killed with signal 6 Naturally, I've backed off quickly. Theoretically, this problem could be attributed to any of the three changes: logging, max processes, different (64-bit) machine. I suspect it's not the "login_max_processes_count" increase. Is it a side-effect of the better logging? (That is, was it always happening but the information simply not getting logged?) Note that our index files (and mail spool (INBOX, folder) areas) are on an NFS (NetApp) shared area accessed by all three classes of our machines: o existing UW-IMAP (which doesn't use the indexes) o yesterday-dovecot (32-bit) o today-dovecot (64-bit) My sneaky suspicion is that this is a subtle 64-bit-ism, either on its own, or in some sort of interaction with an indexes created from yesterday's 32-bit client. (Yes, theoretically, I could try another test to attempt to confirm or eliminate the 32/64 difference. But these issues didn't show up under testing, but only when we began trial service; I can't experiment on the users!) -- : David Lee I.T.

[Dovecot] Received dates problem in Outlook after migration
by James Wyper 13 Oct '06

13 Oct '06

Hello everyone, I've just started using 1.0-beta3 on Ubuntu Dapper, having migrated from an mbox / UW-IMAP combination to a Maildir / Dovecot one. For some reason the mb2md tool failed to recognise some of my mbox files as valid ones, so I migrated my email by running UW-IMAP, copying my folders to local storage in Evolution, then running Dovecot instead and copying the folders back. All seems OK, except that in Outlook 98 all the emails now have the date/time of their migration, not when they were received. This isn't a problem in Thunderbird or Evolution - but my wife uses Outlook and doesn't wish to switch. I've tried using touch to change the timestamps of the mails in my inbox (in ~/Maildir/cur) but this hasn't had any effect. I've also tried deleting ~/Maildir/dovecot.index and ~/Maildir/dovecot.index.cache but this hasn't made any difference either. Something else in dovecot must be being sent to Outlook as the date / time on these emails. Can anyone suggest what it would be and how I might go about changing it (to, for example, the Received: date on the email header?). Thanks in advance, James. ___________________________________________________________ Try the all-new Yahoo! Mail.

[Dovecot] Dovecot freeze - 1.0 rc7 - FreeBSD 6.1
by Floris van den Berg 13 Oct '06

13 Oct '06

Hi, One of my customers currently experiences a dovecot freeze on random accassions. Trying to figure out what's wrong with no luck. Dovecot is running fine, up until it suddenly stops responding. The log file says: dovecot: Oct 05 10:12:26 Info: pop3-login: Disconnected: Inactivity: rip=82.217.29.*, lip=85.17.42.165 dovecot: Oct 05 10:12:29 Info: pop3-login: Disconnected: Inactivity: rip=86.87.152.*, lip=85.17.42.165 dovecot: Oct 05 10:12:30 Info: pop3-login: Disconnected: Inactivity: rip=62.131.94.*, lip=85.17.42.165 dovecot: Oct 05 10:12:30 Info: pop3-login: Disconnected: Inactivity: rip=62.131.94.*, lip=85.17.42.165 dovecot: Oct 05 10:13:17 Info: pop3-login: Disconnected: Inactivity: rip=86.88.180.*, lip=85.17.42.165 No other errors are logged. When i restart dovecot it runs fine again for some time. Sometimes it works for a few days, sometimes just a few hours. There's always a point where it freezes again. Reinstalled dovecot. Fiddled a bit with the auth_worker_max_count and auth_process_size settings. No change in behavior was observed. There's no out of the ordinary cpu or memory use. Any ideas? Floris

Dovecot adds lots of spaces after X-Keywords which could just make it look like that. If it really is a blank line, then it's most likely something else than Dovecot that changes the spaces that way.

[Dovecot] proxy mode
by Jernej Porenta 13 Oct '06

Hello, I've searched the documentation for IMAP/POP3 server with proxy feature, but wiki says that this is not fully implemented yet, but wiki page hasnt been updated for a while. So is there any change since then? Because we are looking for a solution to replace the perdition POP3/IMAP proxy in front of the current UW-IMAP servers and we would really appreciate this feature, since the documentation says that proxy implementation in dovecot does not create a process for every user (problem with large number of concurrent users). Thanks in advance, cheers, Jernej

[Dovecot] Filtering Mails - how?
by Daniel Seichter 12 Oct '06

12 Oct '06

Hello, I've got some problems about understanding, how to filter my incoming mails. I am using dovecot 1.0.beta3 (ubuntu server) and want to implement a filter, where I can filter all my incoming messages (like the ones from the dovecot ml) to special folders within the mailbox of each user (for each user a special set of filters). Is there a chance to do this in dovecot or have I to use another program? My system works like: Fetchmail fetches mails from two mailservers and deliver them to the users inbox Procmail send them to spamassassin for checking about spam Dovecot provides access to the mailbox with IMAP Hope there is an easy way like module for webmin or something else. Thank you Daniel

[Dovecot] 1.0rc8 status report
by David Lee 12 Oct '06

12 Oct '06

A quick status report on how 1.0rc8 behaved in service for a few hours with several hundred simultaneous users, at a site very new to dovecot. Oh, and a question at the end. Summary: Reasonable for a first shot but one significant problem, requiring backing off. Background: We have a long-established UW-IMAP service for a user population of about 20,000 based on a few Linux (Redhat) machines running IMAP/POP and inbound delivery. We try to ensure, but cannot guarantee, that all activity for a given user takes place within one machine. Each machine mounts the INBOX area ("/var/spool/mail"; traditional UNIX mbox) via NFS with tight NFS arguments ("noac,actimeo=0", etc.) and similarly mounts the users' folder areas which are subdirs of their home directories. (We know that Mark Crispin recommends against NFS for UW-IMAP, but we seem to have been OK.) There is also some processing: .forward->"| procmail"->folder-or-inbox Each machine typically has several hundred simultaneous IMAP connections. This has basically worked well, but the UW-IMAP loading has been heavy. The plan: In an ideal world, I would like to restructure the above. But our world is not ideal, so we have to stay with the structure. But we are looking for a transparent (user perspective) migration to dovecot. The dovecot experience: Yesterday, I quietly adjusted a DNS entry to redirect one of the live email hostnames at an additional machine in the "farm", running dovecot 1.0rc8, including deliver/LDA (and taking into account some post-rc7 dovecot changes in this area). On an earlier, smaller-scale test, one problem had been some periods of "temporary authentication failures". Increasing "login_processes_count" and "login_max_processes_count" (each by a factor of 8) seems to have fixed this, and I'm not aware of any problems in that area yesterday. It basically went well. But just over two hours hours later I had to back off, because of a significant dovecot problem, namely that dovecot crashed, almost silently. The only traces of this event in the log file seem to be: Oct 10 16:26:12 [...] dovecot: child 24525 (login) returned error 89 Oct 10 16:26:14 [...] dovecot: Login process died too early - shutting down Any thoughts? Any fixes? If the problem needs debugging (or additional data/log collection) how might that be attempted in this environment? -- : David Lee I.T.

[Dovecot] Issues with Dovecot/Pam/nss_ldap
by Ejay Hire 12 Oct '06

12 Oct '06

Hello all. I have experienced an unusual behaviour from dovecot which I believe to be related to some interaction between dovecot and nss_ldap/Pam. Centos/Postfix/mbox(es)/Openldap/dovecot. The box is using PAM with ldap, and is also running BIND, SAMBA, and DHCPD. Dovecot 1.0rc2 from source. I left dovecot at the default, to use PAM for authentication and guess the mailbox. This worked well, except during peak times, dovecot would "hang", waiting an exceptionally long time after connecting before doing authentication. The users would report this as "Send/receive stuck on 64%" or something like that. During this time, I would note a number of <defunct> dovecot processes in ps. Increasing the number of idle login proceses in the pool to ridiculously high values (30) did not affect the symptom. Restarting dovecot would immediately resolve the issue. I believe this to be related somehow to dovecot's PAM interaction, because I was able to work around it by setting dovecot to talk directly to LDAP. Googling found isolated reports of similar behaviour in the Fedora Core 3 bug list at Redhat. It's rare I can help in project as important as dovecot, so I'm willing to spend some time tracking this down. What information can I provide to help? Thanks Ejay Hire

[Dovecot] Fwd: Received dates problem in Outlook after migration
by James Wyper 12 Oct '06

12 Oct '06

Having looked at this again, I think I have a hypothesis: 1. Outlook is ignoring the date/timestamps on the files in my Maildirs 2. The file names of my transferred files follow a similar pattern (they start with near-identical numbers) 3. Dovecot's file naming scheme for mails must relate somehow to the date that they were created / transferred / received 4. If I can therefore **rename** the files correctly to reflect their sending date then I can fix my problem Does this make sense? Can anyone point me in the direction of a spec that says how Dovecot names its files?

I believe that when login_max_processes_count is reached (the default is 128) Dovecot is crashing rather than handling that condition semi gracefully. The reason I think this is because we have a cluster of servers that do search indexing for our IMAP mailboxes, and due to a bug this week, those servers started slamming one of our IMAP servers with rapid login failures. Dovecot crashed frequently with "Login process died too early - shutting down" while this was occurring. And then also under normal operation we were seeing Dovecot crash about once per day on random servers when that server was under a heavy IMAP load. To work around this we switched to "login_process_per_connection = no" and bumped up our file descritor limit ("ulimit -n"). No crashes since. But probably still needs to be fixed in the code. Bill

Hi, I compiled Dovecot and Mysql on two different servers each with the same options. Dovecot connects successfully on Server B.

[Dovecot] POP +OK CR LF Question
by Phil Udel 11 Oct '06

11 Oct '06

HI. I just finished installing a new mail server running CentOS Ver 4. and I am running sendmail with devecot 0.99.11. Everything is working fine except for a customer of mine is using a tool that does pop requests. And his tool is failing waiting on a CR LF in the +OK. I did a small hex dump of my old pop and the dovecot pop and he is right. Docevot POP does not end its +OK with a CR LF. I looked around but I don't see where I can make that change. Can anyone please help. Thanks

[Dovecot] Problems with LDA and vitual mailboxes
by Daniel Frickemeier 11 Oct '06

11 Oct '06

Hello, I try to set up dovecot LDA with virtual domains/mailboxes to use sieve. I use dovecot 1.0_rc7 with sieve dovecot-sieve-20060726 . All datas about the virtual domains and mailboxes are stored in a mysql-database. And without using the LDA delifer agent, everything works fine. But when I try to use LDA (even without sieve), I got a delivery failture. I followed the wiki-howto http://wiki.dovecot.org/LDA to set up LDA support and added /etc/postfix/maser.cf: # Dovecot LDA dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -d ${recipient} /etc/postfix/main.cf: dovecot_destination_recipient_limit = 1 virtual_transport = dovecot for postfix. In dovecot.conf I added: auth default { # Space separated list of wanted authentication mechanisms: # plain login digest-md5 cram-md5 ntlm rpa apop anonymous gssapi mechanisms = plain login # SQL database passdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /etc/dovecot/dovecot-sql.conf } # SQL database userdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /etc/dovecot/dovecot-sql.conf } socket listen { master { path = /var/run/dovecot-auth-master # use this for LDA, the dovecot-auth will NOT work mode = 0600 user = virtual #group = mail # Or alternatively mode 0660 + LDA user in this group } client { path = /var/run/dovecot-auth # use this for postfix mode = 0600 user = posfix # postfix user #group = mail # Or alternatively mode 0660 + postfix user in this group } } } protocol lda { log_path = /var/tmp/dovecot-lda.log { And in dovecot-sql # Dataabase driver: mysql, pgsql driver = mysql # Currently supported schemes include PLAIN, PLAIN-MD5, DIGEST-MD5, and CRYPT. default_pass_scheme = CRYPT #default_pass_scheme = PLAIN-MD5 # Database options connect = host=localhost dbname=$DB user=$USER password=$PASSWD password_query = SELECT password FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT maildir, 1002 AS uid, 1004 AS gid FROM mailbox WHERE username = '%u' AND active = '1' # eof But when I send a mail to a vitual user, I got the following log entries in mail.log: Oct 11 08:40:38 server postfix/pipe[11673]: D39A5664420: to=<zigulle(a)zigulle.de>, relay=dovecot, delay=0.08, delays=0.06/0/0/0.03, dsn=4.3.0, status=deferred (temporary failure) and in /var/tmp/dovecot-lda.log: deliver(zigulle(a)zigulle.de): Error: userdb(zigulle(a)zigulle.de) didn't return a home directory has anyone here a hint, where the Problem ist? cu Daniel -- TELEKOM-Mitarbeiter, die keine TELEKOM-Aktien kaufen, sollten wegen Verwendung von Insider-Wissen bestraft werden.

[Dovecot] RC8 - Creating maildir

I just setup a new mail server with maildir and Dovecot RC 8 I noticed that when I login via POP3 with a username that do not have a maildir yet Dovecot logs this line: Oct 11 11:46:52 gw dovecot: stat(/var/spool/mail/xxxx/) failed: No such file or directory After that Dovecot correctly creates the maildir structure Wouldn't it be better to log a message like "Creating maildir structure for user xxxxxx"?

[Dovecot] How Dovecot handles email changed by file operations
by Craig Jackson 10 Oct '06

10 Oct '06

Hi, We have been using Courier-imap for a few years. I am always in the process of reviewing competing software, and hence my interest in Dovecot. Question: If email files are moved between IMAP folders (on the same IMAP server or a different one) or deleted using shell scripts, how does this impact Dovecot's indexes or its method of keeping track of the email? How likely is index or file corruption or race condition? An example, is the centralized removal of mail in all users' Junk folder older than 30 days. We use Maildir format and Dovecot 1.0-RC7 with Mysql. We have about 150 users. Thanks. Craig

[Dovecot] POP3 - Mark messages as read
by Jose Gervasio Gomiz 10 Oct '06

10 Oct '06

Hi all. I have a little problem with Dovecot. My POP3 users can retrieve their emails without problem, but if they have "Leave mail in server" (or similar) active in their clients, their mboxes doesn't get updated marking those messages as read. If I access their mboxes locally with "mail -f username" I can see every message marked as non-read, something that never happened before when I used qpopper. I should note that when they retrieve their emails afterwards those previously received doesn't arrive again (correct behavior). My setup is: RHEL 4 Update 4 dovecot-0.99.11-4.EL4 (last version in RH Updates) mbox format, external POP3, local only IMAP (Squirrelmail) I couldn't find references to this in /etc/dovecot.conf, the FAQ or via web searching. Should I upgrade to dovecot-1.x to solve this? Even if RH doesn't support it yet? Any info would be greatly appreciated. Jose Gomiz

[Dovecot] RC8 failing...
by Timothy Meader 10 Oct '06

I just tried upgrading from RC7 to RC8 this morning, and I'm seeing an issue I've never seen before. On my first POP3 login, all is fine, but any subsequent logins seem to fail with the message: dovecot: Oct 10 11:04:31 Error: Maximum number of mail processes exceeded In the dovecot log file. I'm also oddly seeing the message: Oct 10 11:01:05 popbkup pop3-login: [ID 799321 mail.crit] Dovecot version mismatch: Master is v1.0.rc7, login is v1.0.rc8 (if you don't care, set version_ignore=yes) in the messages file on my system. Don't really understand that one, and I've done a complete shutdown of all dovecot or *-login *-auth processes prior to the "make install" for RC8. The only possible config file change I can think of that might've caused this (that was mentioned in the release notes for RC8) is the default_mail_env value, however, I believe mine is fine: mbox:~/mail:INBOX=/var/mail/%1u/%1.1u/%u This is for an actual mailbox with a two character hash for the maildrop directory. I was looking forward to giving RC8 a spin, but I've had to revert back to RC7 for now.

[Dovecot] dovecot, procmail and deliver
by David Lee 09 Oct '06

09 Oct '06

(Using dovecot 1.0 RC7 on Fedora Core 5) <scene set> Hitherto we have used UW-IMAP on a "farm" of Linux machines mounting NFS from a NetApp. (The UW-IMAP author doesn't like use of NFS, but with careful use of NFS mount arguments ('noac,actimeo=0' etc.) and trying to ensure that all activity for a given user takes place within one machine in the farm, we seem to have been OK.) We have also used UW-IMAP's 'tmail' (in sendmail.cf) and 'dmail' (from any user procmail recipes), so that access to the INBOX has been consistently UW-IMAP software. We are now considering doing a transparent migration to dovecot to improve performance. </scene> --- First: a general question: To complement the UW->dovecot migration of the IMAP daemon (reading the INBOX and folders), ought I to do a similar delivery-side migration from [UW] tmail/dmail to [dovecot] 'deliver'? It would feel safer this way, but maybe I worry too much... --- Second: "deliver" seems to add an unconditional "From " line at the start of each delivery. From sendmail, using the 'n' flag, "Mlocal F=...n..." that is OK. (Although I'm not convinced that "dovecot.deliver", nor its two-space separator (emphasis on "two") from the following date are ideal. Nor, come to that line's lack of "@somewhere".) But from a procmail recipe, I end up with two "From " lines. Surely this is incorrect. How can this be reduced to one? Shouldn't "deliver" ensure that there is only "From " line? --- Third: Would it be possible for "deliver" to do a "syslog" entry to confirm final delivery into the destination mailbox, please? (I could try and produce a patch, but someone else with more dovecot familiarity could probably do the job must more quickly and probably also more cleanly!)

[Dovecot] patch: mailboxcasecmp()
by Frank Cusack 09 Oct '06

09 Oct '06

Here is a patch which adds mailboxcmp() and mailboxcasecmp() functions, similar to mailbox_equals(). Names were chosen to match strcmp() and strcasecmp(). I needed this for Johaness Berg's dspam plugin. It watches a folder "SPAM" and forcing this to be uppercase is unacceptable for me. (I also had to modify the plugin to use the new routine.) It's against dovecot-1.0.beta8 but should be trivial to port to CVS. -frank

Hi, I'm trying to use dovecot-1.0.rc7. Before I've used dovecot-1.0 from nightly cvs build of August 08, 2006. It worked perfectly, on Linux 64-bit, you can see spec and patches at http://www.sisyphus.ru/srpm/dovecot/ When I tried to upgrade to rc7 and to recent nightly cvs builds with the same configuration and patches (provided necessary adaptations), it builds O.K, but can not move messages from folder to folder. I've tried the following mail clients: thunderbird-1.5.0.7, evolution-2.0.2, sylpheed-claws-2.0 and KMail-1.7.1 (all from Centos-4.4). KMail refuses to copy (or to move) multiple selected messages, saying:" Error while copying messages.Connection to Server Closed Unexpectedly ...". Evolution is not able to open folders at 3-rd level (like dovecot/2006/09), or it is so slow that I was not able to test moving/copying messages in it. Sylpheed-claws died whan I tried this message copying. Thunderbird tries to move infinetly in a loop, filling the dovecot's log with lines: --- Sep 28 12:56:25 alt64 dovecot: imap-login: Login: user=<seriv>, method=plain, rip=66.80.117.2, lip=192.168.10.8, TLS Sep 28 12:56:25 alt64 dovecot: IMAP(seriv): file mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) Sep 28 12:56:25 alt64 dovecot: child 25177 (imap) killed with signal 6 Sep 28 12:56:25 alt64 dovecot: imap-login: Login: user=<seriv>, method=plain, rip=66.80.117.2, lip=192.168.10.8, TLS Sep 28 12:56:25 alt64 dovecot: IMAP(seriv): file mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) Sep 28 12:56:25 alt64 dovecot: child 25183 (imap) killed with signal 6 --- (approximitely 2 cicles per second). And when I reinstalled back the previously worked version of dovecot, the problem remains. -- With best regards, Sergey Ivanov.
