[Dovecot] sievec segfaults
by interfaSys sàrl 24 Apr '12

24 Apr '12

Hello, sievec segfaults when it reads a file. I've tried with both the standard and gold linker. I've tried with various sieve files and they all make it crash. I've compiled pigeonhole with -ggdb, but I'm not getting much info Program received signal SIGSEGV, Segmentation fault. 0x0000000800b8e587 in strlen () from /lib/libc.so.7 (gdb) bt full #0 0x0000000800b8e587 in strlen () from /lib/libc.so.7 No symbol table info available. #1 0x0000000800a12e8c in str_append () from /usr/lib/dovecot/libdovecot.so.0 No symbol table info available. #2 0x000000080077f02d in sieve_binary_save () from /usr/lib/dovecot/libdovecot-sieve.so.0 No symbol table info available. #3 0x0000000000605bf0 in environ () No symbol table info available. #4 0x0000000000000000 in ??

[Dovecot] Dovecot Virtual Users with Users Domain Mapping
by Piotr Maier 24 Apr '12

24 Apr '12

I have successfully compiled, configured and ran Dovecot with virtual users feature. Here's part of my /etc/dovecot.conf configuration file: mail_location = maildir:~/Maildir auth default { mechanisms = plain login userdb passwd-file { args = /home/%d/etc/passwd } passdb passwd-file { args = /home/%d/etc/shadow } socket listen { master { path = /var/run/dovecot/auth-worker mode = 0600 } } } I faced one issue I can't resolve myself. Is there anyway to create users' domains mapping and provide username in mail_location? Example of usersdomains file: domain.com:user1 domain2.org:user3 Examples: 1. currently I have /home/domain.com/user/Maildir 2. I'd like to have /home/SYSTEM_USER/domain.com/user/Maildir Can I achieve this somehow?

[Dovecot] quota not being calculated
by Cor Bosman 23 Apr '12

23 Apr '12

It looks like my quota isnt being calculated properly after I started setting quota to a specific folder. The quota in that folder is always starting out at 0, and only new email is being added to the quota. If I remove the maildirsize file, and recalculate, it still starts at 0. Once email arrives in the folder, it gets added to maildirsize. This is with maildirquota, in perhaps a bit of an exotic config. The idea is to set a specific quota to Spam folder, using the trash plugin to keep it at a certain size. . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam quota" * QUOTA "User quota" (STORAGE 40848 1228800) * QUOTA "Spam quota" (STORAGE 0 20000) . OK Getquotaroot completed. Once 1 email gets added: .Spam# cat maildirsize 20480000S 0 0 2017 1 namespace { hidden = no ignore_on_failure = no inbox = yes list = yes location = maildir:%h:INDEX=/var/spool/mail/dovecot-control/indexes/%1u/%2u/%u:CONTROL=/var/spool/mail/dovecot-control/%1u/%2u/%u/INBOX prefix = separator = / subscriptions = yes type = private } namespace spam { hidden = yes ignore_on_failure = no inbox = no list = yes location = maildir:%h/.Spam:INDEX=/var/spool/mail/dovecot-control/indexes/%1u/%2u/%u/.Spam:CONTROL=/var/spool/mail/dovecot-control/%1u/%2u/%u/.Spam prefix = Spam/ separator = / subscriptions = no type = private } plugin { quota = fs:User quota quota2 = maildir:Spam quota:ns=Spam/ quota2_rule = *:storage=20000K sieve = /var/spool/mail/dovecot-control/sieve/%1u/%2u/%u/dovecot.sieve sieve_before = /etc/sieve/before sieve_dir = /var/spool/mail/dovecot-control/sieve/%1u/%2u/%u/scripts trash = /etc/dovecot/conf.d/dovecot-trash.conf.ext } (full config: http://pastebin.com/Mui4X7Zh)

Hello, after finally having managed to setup up dovecot with virtual users and public folders I tried to get it connected to postfix.

[Dovecot] questions about SPECIAL-USE and virtual
by l.chelchowski＠eurocar.pl 23 Apr '12

23 Apr '12

Hi, I have some questions about Special-Use and virtual namespace: I want to create a virtual namespace with mailboxes: Sent, Unread, Flagged, All. 1. Is it enough to put in the config file: mailbox virtual/Sent { auto = subscribe special_use = \Sent } mailbox virtual/Unread { auto = subscribe special_use = \Unread #Is it correct? } mailbox virtual/Flagged { auto = subscribe special_use = \Flagged } mailbox virtual/All { auto = subscribe special_use = \All } and it would displays mail from every namespace I have subscribed (Shared, Public)? OR I have to make also dovecot-virtual files? 2. In dovecot-virtual file can I put for mailbox virtual/Sent something like: * \Sent 3. Is the http://wiki2.dovecot.org/Plugins/Virtual full documented, if not , where can I find it? 4. Is there a documentation for Special-Use? -- Łukasz

[Dovecot] Bug in HIGHESTMODSEQ when MODSEQ tracking is not enabled for version 2.0.18.
by Glenn Wurster 23 Apr '12

23 Apr '12

Greetings, I'm new to the list. I have encountered what I believe to be a bug in the return of HIGHESTMODSEQ when talking to a IMAP client. HIGHESTMODSEQ does not appear to be incrementing when a new message arrives. The exact steps I took are: 1) Create a new mail account 2) Send a mail to the account, check that you can receive the email. Send a second mail to the account. 3) perform a SELECT on the mailbox from a new session. PMLK4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest PMLK4 OK [READ-WRITE] Select completed. 4) Retrieve the mail. Then perform another SELECT on the mailbox from yet another session. LLEP4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest LLEP4 OK [READ-WRITE] Select completed. 5) Send another mail to the account, and check SELECT again. FKDA4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 3 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 4] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest FKDA4 OK [READ-WRITE] Select completed. It appears as if HIGHESTMODSEQ is not being updated. I can get HIGHESTMODSEQ to start updating correctly if I send a "UID FETCH 1 MODSEQ" or similar command, which appears to enable MODSEQ tracking at the server (according to the comment around line 173 in file src/lib-index/mail-index-modseq.c), but until that command is sent, MODSEQ tracking is not enabled and hence HIGHESTMODSEQ is always going to return 1. According to RFC4551, the combination of HIGHESTMODSEQ and UIDVALIDITY should be sufficient to determine if the metadata associated with the mailbox has changed, but in this case looking at only those two parameters does not yield sufficient information about changes in the mailbox. The mail client I'm using relies on the combination of HIGHESTMODSEQ and UIDVALIDITY to determine if there are changes in the mailbox, and hence does not see new mail come in. It seems that Dovecot should not be returning HIGHESTMODSEQ in response to a command if MODSEQ tracking is not enabled, but I could be wrong. I've attached my configuration (it's Dovecot 2.0.18 running on Debian Stable). Let me know if you need more information.

[Dovecot] imapc / namespace question
by René Neumann 23 Apr '12

23 Apr '12

Hi, I've got two questions regarding imapc and namespaces: 1) Is there a way of stating, that I only want part of the hierarchy on the end of an imapc connection to be available here? My "problem": On the other end the layout is: INBOX.Shared.{some,nice,folders} If I mirror this into my dovecot hierarchy with prefix "Gemeinsam" I get the following folder structure: Gemeinsam.INBOX.Shared.{some,nice,folders} But I want to ignore the two top-most parts of the hierarchy, i.e. I want it to look: Gemeinsam.{some,nice,folders} Is this possible? I tried with 'location=imapc:INBOX.Shared.' but this did not change anything. 2) "Private" namespaces only make sense, if location contains something user-specific like "%u" or "~". Is this correct? If yes: Is there some other way to make something like an imapc connection only appear for one user, if there is nothing in the location or imapc_user to denote the user it belongs to and hence I cannot use "private"? The only way I see currently is to use "shared" and set up ACLs to forbid all users except one to access the namespace (which gets slightly ugly as I have to use global ACLs, as -- I think -- there is no way to store ACLs for an imapc storage). Thanks, René

This is just one dovecot IMAP client process moaning after another user client process pulled the rug out from under it by modifying the mailbox. I get a few dozen log entries of this sort per week with ~200 IMAP users without shared access. Unless your users actually complain about a problem, I think it's safe to ignore them.

[Dovecot] sieve against ldap in Dovecot 1.2 vacation messeage
by Victor Oñate 22 Apr '12

22 Apr '12

Hi. I need configure "sieve" against ldap this is my file configuration dovecot.conf plugin { quota = dirsize:user sieve_dir = ~/sieve } protocol lda { mail_plugins = sieve } auth default { mechanisms = plain passdb pam { } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = nobody } I dont know what I have to put in dovecot-ldap.conf, ofcourse I have a atribut in LDAP by user with a vacation messeage "I'm out of office, please contact Mr. Black" this is dovecot-ldap.conf hosts = server auth_bind = yes ldap_version = 3 base = dc=dominio,dc=uk deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mail=Maildir,mailQuotaSize=quota_rule=*:storage=%$ user_filter = (&(objectClass=posixAccount)(uid=%u)) The principal idea is keep the control the message by user with LDAP and Dovecot(IMAP). without touching the postfix configuration file is that possible, or am I dreaming. Thanks.. Victor Oñate.

If not, look at this page to configure logging http://wiki.dovecot.org/LDA That's your best chance at finding out the problem. I don't have virtual users, so I can't venture to say whether this is part of the problem. I know I had to fiddle with the mailer flags (you have "DFMPhnu9") to get my setup working, but I don't remember what I did or why. Try adding the "S" flag and see if that helps.

[Dovecot] migrate 15K users to new domain name
by Jan-Frode Myklebust 21 Apr '12

21 Apr '12

I need to migrate 15K users to a new domain name, and plan to use "dsync mirror" in the transition phase. Could someone confirm that this should work: Before giving users access to new-domain do a first sync to get all the stale data over: for user in $old-domain; do dsync mirror $user@old-domain $user@new-domain done Configure sieve vacation filter to forward all messages from $user@old-domain to $user@new-domain, and notify sender of changed address. Give users access to both new-domain and old-domain, and do a final sync. for user in $old-domain; do dsync mirror $user@old-domain $user@new-domain dsync mirror $user@old-domain $user@new-domain # twice in case the first was slow drop all messages for $user@old-domain Leave notice message for $user@old-domain saying he should use new-domain done Wait a few weeks/months, and then drop all users@old-domain. Does this look sensible? -jf

[Dovecot] mbox folders on-disc layout
by John Robinson 21 Apr '12

21 Apr '12

I'd like to change the on-disk layout for my mboxes from being ~/mail/foo/bar to ~/mail/foo.bar so that I can have folders containing both messages and subfolders, without having subfolders beginning with . and then having to do all the other fiddling with locations of index files etc. that goes along with LAYOUT=maildir++, and also leaving the filesystem layout looking sensible so my users see their mailboxes instead of the index and control files. Is this possible or do I need to patch something? (CentOS 6, dovecot 2.0.9) Cheers, John.

[Dovecot] Error in logs indicating broken files
by Steve Campbell 20 Apr '12

20 Apr '12

Still new to dovecot, I'm seeing a couple of errors in my log file indicating corruption of index files. Error: Corrupted index cache file/home/xxxxxx/mail/.imap/sent-mail/dovecot.index.cache: Broken virtual size for mail UID 67: 1 Time(s) Error: FETCH [] for mailbox ~/mail/sent-mail UID 67 got too little data: 6203 vs 7478: 1 Time(s) This account is used by multiple users, but it is not a shared account (haven't set any of those up yet - still new to me), so I would expect corruption possibilities when multiple users modify the account folders in some manner. Until I get some experience under my belt and make this a truly "shared" account, is there any way to resolve the corruption of the files mentioned above? Maybe just delete them? thanks steve campbell

[Dovecot] array code issue ?
by Tim Ruehsen 20 Apr '12

20 Apr '12

Hi, I just took a look into the dovecot 2.1 sources and just saw a possible issue in array.h. This code snippet as an example: #static inline void * #array_get_modifiable_i(struct array *array, unsigned int *count_r) #{ # *count_r = array->buffer->used / array->element_size; # return buffer_get_modifiable_data(array->buffer, NULL); #} array->buffer->used and array->element_size are of type 'size_t' which is 64bit on amd64 and others while 'count_r' is a 32bit value. At least, I see ugly warnings with -Wconversion (which I personally like to use). I know, it is unlikely that 'array->buffer->used / array->element_size' exceeds 32bit range. But then, dovecot's source is so well written, that the above code seems to disturb dovecot's code aesthetics. And who knows... in a few years (when we have THz and TBytes on our desktops) emails (and array sizes) might exceed everything that we think of today. Tim

What are the pros and cons of both? Especially in regards to performance, stability, management & maintenance? I really appreciate feedback. We're on a time-crunch to migrate from a debian 5 box w/ dovecot 1.1 to a debian 6 box w/ dovecot 2.0.9 (built from source).
