Error: Filename keeps changing
by Ward Romp 24 May '16

24 May '16

Dear all, Two days ago, my ldap server (for authentication) crashed and I had to set up a new one. Everything works fine except the mailbox for one user (let's name him debugger). When I try to access his mail whatever way, dovecot complains about "Error: maildir_file_do(........): Filename keeps changing" For example, a command "doveadm copy -u debugger(a)boontje.net Archive mailbox Netspar" returns doveadm(debugger(a)boontje.net): Error: maildir_file_do(/var/mail/vmail/boontje.net/debugger/mail/Netspar/cur/14230…: Filename keeps changing doveadm(debugger(a)boontje.net): Error: Copying message UID 1 from 'Netspar' failed: Internal error occurred.

Accessing the mails via a mail client (Roundcube, Thunderbird, etc...) give the same error. Dovecot runs on a virtual machine and the mailboxes are stored via a CIFS-share on a NAS. I rebooted both machines, checked the filesystem (no errors), CIFS-share, directories and mail files are readable and writeable by dovecot user (vmail on the mail server). The mails are intact, cat <filename> shows the full mail. I'm baffled, any suggestions?

Growing number of dovecot processes
by John Oliver 24 May '16

24 May '16

OS is CentOS 6, dovecot-2.0.9-19 Just started using this server as a replacement for an old Debian server running an old dovecot. The number of dovecot processes just grows and grows until there are 100 concurrent login processes (we have maybe 40 or 50 users), and then nobody can log in any more. A reload resets, but the number of stuck processes climbs very quickly. We're authenticating against an OpenLDAP. Unfortunately, this system is not connected to the Internet so I cannot paste logs or output of commands. I've been Googling, but aren't hitting on the right phrase to describe this issue to uncover possible answers :-( If anyone can get me pointed in the right direction, I'd appreciate it. -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

No implicit INBOX with mailbox_list_index = yes?
by Karsten Heiken 23 May '16

23 May '16

Hello all, I am running a Dovecot Cluster (2.2.13 and 2.2.23 show the same behaviour) using dsync replication (as described here: http://wiki.dovecot.org/Replication) In addition to that I allow users to share mailboxes using IMAP ACLs. My problem is that I need to set "mail_shared_explicit_inbox = yes" if I want my users to see Inboxes of other users. If I leave mail_shared_explicit_inbox = no, then the user cannot see any Inboxes of other users: > * LIST (\Subscribed \UnMarked) "/" Sent > * LIST (\Subscribed \UnMarked) "/" Drafts > * LIST (\Subscribed) "/" INBOX When I set explicit_inbox = yes, then I can see the shared mailboxes: > * LIST (\Subscribed \UnMarked) "/" Sent > * LIST (\Subscribed \UnMarked) "/" Drafts > * LIST (\NonExistent) "/" shared > * LIST (\NonExistent) "/" shared/bob(a)luis.uni-hannover.de > * LIST (\Subscribed) "/" shared/bob(a)luis.uni-hannover.de/INBOX > * LIST (\Subscribed) "/" INBOX After some digging I found out that if I set mailbox_list_index = NO, then everything works even without explicit_inbox: > * LIST (\Subscribed) "/" Sent > * LIST (\Subscribed) "/" Drafts > * LIST (\NonExistent) "/" shared > * LIST (\Subscribed) "/" shared/bob(a)luis.uni-hannover.de > * LIST (\Subscribed) "/" INBOX Since we are migrating from Cyrus to Dovecot, our users are used to the behaviour of explicit_inbox = no, so I would like to keep it that way. I would simply leave mailbox_list_index disabled, but the comment states it is required for NOTIFY, which in turn is required by the rolling replication -- am I corrent? > # Mailbox list indexes can be used to optimize IMAP STATUS commands. They are > # also required for IMAP NOTIFY extension to be enabled. > # mailbox_list_index = yes What am I doing wrong or don't understand?

Dovecot-FTS:

We're running Dovecot with SOLR Lucene 5.5 and we have several errors like badMessage: 414 for HttpChannelOverHttp@5216da8e{r=0,c=false,a=IDLE,uri=-} 20.5.2016, 14:10:16 and URI is too large >8192 in our solr-logfile. I don't know if this is a problem in SOLR or in Dovecot, so I just bring it to your attention.

dovecot-sieve: require "mailbox" fails (Unbuntu 16.04)
by Karim 'Kasi Mir' Senoucci 20 May '16

20 May '16

Hello everyone, I'm moving some old procmail recipes to sieve, but having problems with it. The problem lies with the mailbox extension, which I'm trying to use as proposed in an example in the Dovecot wiki: > require ["variables","date","fileinto","mailbox"]; > > # Extract date info > if currentdate :matches "year" "*" { set "year" "${1}"; } > if currentdate :matches "month" "*" { set "month" "${1}"; } > > # Archive Dovecot mailing list items by year and month. > # Create folder when it does not exist. > if header :is "list-id" "dovecot.dovecot.org" { > fileinto :create "INBOX.Lists.${year}.${month}.dovecot"; > } I'm trying a similar rule (different condition, different mail folder), but cannot seen to get it to work. I always get the errors: > .DOVECOT: LINE 16: ERROR: UNEXPECTED '}' FOUND AT (THE PRESUMED) END OF FILE. > .DOVECOT: ERROR: PARSE FAILED. I'm using the standard dovecot packages from Ubuntu 16.04: > II DOVECOT-CORE 1:2.2.22-1UBUNTU2 AMD64 SECURE POP3/IMAP SERVER - CORE FILES > II DOVECOT-IMAPD 1:2.2.22-1UBUNTU2 AMD64 SECURE POP3/IMAP SERVER - IMAP DAEMON > II DOVECOT-MANAGESIEVED 1:2.2.22-1UBUNTU2 AMD64 SECURE POP3/IMAP SERVER - MANAGE SIEVE SERVER > II DOVECOT-SIEVE 1:2.2.22-1UBUNTU2 AMD64 SECURE POP3/IMAP SERVER - SIEVE FILTERS SUPPORT I was under the impression that these sieve extensions, including "mailbox", are builtin into dovecot/pigeonhole, or at least packaged into dovecot-sieve. Is that not the case? How can I get the example working under Ubuntu linux 16.04? Do I need to add or reconfigure something by hand? Thanks in advance for any help on the subject. Greetings Kasi Mir

Re: BUG?: Dsync over piped process (DSYNC_RUN_TYPE_CMD): EPIPE if X (done) is received in another write after F (finish)

Hi Timo, The below solved the problem for me as far as I can tell I was getting a EPIPE about 1:30 dsync runs over the socket.

I think this is intentional. The F(inish) tells the final response whether everything was OK or not, so all the work is done after that. The 'X' is described in code as: > > /* notify remote that we're closing. this is mainly to avoid > "read() failed: EOF" errors on failing dsyncs */ > o_stream_nsend_str(ibc->output, > t_strdup_printf("%c\n", items[ITEM_DONE].chr)); > > and on the receiving side: > > if (line[0] == items[ITEM_DONE].chr) { > /* remote cleanly closed the connection, possibly because of > some failure (which it should have logged). we don't want to > log any stream errors anyway after this. */ > dsync_ibc_stream_stop(ibc); > return DSYNC_IBC_RECV_RET_TRYAGAIN; > } > > So I think it only matters in error handling.

BUG?: Dsync over piped process (DSYNC_RUN_TYPE_CMD): EPIPE if X (done) is received in another write after F (finish)
by J. Nick Koston 19 May '16

19 May '16

Hi, It appears that dsync closes the file handle once it gets the F (finish) response even if it hasn’t received the X (done) response. If the X (done) response gets delivered in another write this will generate EPIPE in the connected process. This is much easier to replicate over SSL, however the trace is provided without SSL since its easier to see whats going on. Thanks J.

mailbox.auto ignores dovecot-uidlist.lock
