Possible RENAME bug
by Gabriele Bulfon 05 Jun '17

05 Jun '17

Hello, I'm having some trouble working on a webapp managing the imap tree on Dovecot. The same doesn't happen on other imap servers (e.g. Cyrus). Looks like if I receive shared folders from another user, and try to rename a folder in it, the rename command returns "ok", then if you list the new folder name, it isn't there. Looks like you've lost all the original folder because if you try listing the parent folder, you don't have nor the original nor the new name, even trying to logout/disconnect and reconnect/login. Luckily nothing is lost actually, if you try to create a new folder on the parent folder, and then list the parent folder, you get both the newly created one and the renamed one also appears magically! Here is the IMAP trace to reproduce: *** ON ACCOUN RECEIVING SHARED FOLDER *** PREPARE A FOLDER IN SHARED TREE WITH JUST ONE CHILD "aaaa" *** THEN RENAME aaaa FOLDER TO bbbb *** AFTER "OK Rename" FOLDER IS NOT PRESENT IN LIST A3 LIST "" Shared/gabriele.prova(a)sonicle.com/Junk/aaaa * LIST (\HasNoChildren) "/" Shared/gabriele.prova(a)sonicle.com/Junk/aaaa A3 OK List completed.

Problem with LMTP
by Angel L. Mateo 05 Jun '17

05 Jun '17

Hello, I'm having a problem with LMTP in a proxy server since I upgraded from 2.1.16 to 2.2.28. In my logs I have: Apr 26 12:54:17 musio12 dovecot: lmtp(2082): Fatal: master: service(lmtp): child 2082 killed with signal 11 (core dumped). As far as I could check the message is delivered in a later connection. I have enabled core dumped files, but how could I debug it? -- Angel L.

Retrieving mail from read-only mdbox
by Mark Moseley 05 Jun '17

05 Jun '17

This is a 'has anyone run into this and solved it' post. And yes, I've been reading and re-reading TFM but without luck. The background is that I'm working on tooling before we start a mass maildir->mdbox conversion. One of those tools is recovering mail from backups (easy as pie with maildir). We've got all of our email on Netapp file servers. They have nice snapshotting but the snapshots are, of course, readonly. My question: is there a doveadm command that will allow for email to be retrieved from a readonly mdbox, either directly (like manipulating the mdbox files directly) or by doveadm talking to the dovecot processes? Ideally, there'd be something like doveadm dump, but that could dump selected message contents. I've tried using IMAP with mail_location pointed at the snapshot, but, though I can get a listing of emails in the mailbox, the fetch fails when dovecot can't write-lock dovecot.index.log. If anyone has gotten something similar to work, I'd love to hear about it. A working IMAP setup would be the ideal, since it's more easily automatible (but I'll take whatever I can get). Any and all hints are most welcome!

quota clone + mysql + duplicate key
by Dimos Alevizos 05 Jun '17

05 Jun '17

I'm trying to setup quota clone with mysql on dovecot 2.2.29.1. I see in the wiki that the table is always updated to the new value (https://wiki.dovecot.org/Plugins/QuotaClone) : > Every time quota is updated, the value is updated to the cloned dict. > There are race conditions with it so the quota may not always be 100% > correct. The old value is always replaced with the new one though (not > just incremented/decremented) so the cloned quota is never too much wrong. But the queries I see don't agree : 1186029 Query BEGIN 1186029 Query INSERT INTO quota (bytes,messages,username) VALUES (25002030,226,'user(a)domain.tld') ON DUPLICATE KEY UPDATE bytes=bytes+25002030,messages=messages+226 1186029 Query COMMIT Is it a bug or am I missing something in my configuration ? The relevant part of the config : dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } plugin { quota = count:User quota quota_clone_dict = proxy::sqlquota quota_exceeded_message = Quota for this mail account has been exceeded, please try again later. quota_grace = 1M quota_vsizes = yes } map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } Dimos

ACL File
by Bobber 02 Jun '17

02 Jun '17

I'm getting inconsistent behavior from my acl file. I have an acl vfile configured with this: > Jobs$* anyone lrwikst > $* user=bob.wooldridge(a)edm-inc.com lrwstipekxa > $* user=michael.user(a)edm-inc.com lrwstipekxa > Jobs$* user=bob.wooldridge(a)edm-inc.com lrwstipekxa > Jobs$* user=michael.user(a)edm-inc.com lrwstipekxa The Jobs folder is a public shared folder. I want just the two users to be able to have complete control of anything in the shared Jobs folder. Currently, user bob is able to move folders to sub folders but user michael is sometimes able to move folders but mostly not. I am using Thunderbird as the mail client. Sometimes I can restart Thunderbird and it will allow one operation but subsequent operations error out with Thunderbird saying the user does not have permissions. Here's my doveconf -n: > # 2.2.30.1 (eebd877): /usr/local/etc/dovecot/dovecot.conf > # OS: Linux 3.16.0-0.bpo.4-amd64 x86_64 Debian 7.11 > auth_cache_size = 8 k > auth_debug = yes > first_valid_gid = 89 > first_valid_uid = 89 > last_valid_gid = 89 > last_valid_uid = 89 > listen = * > log_path = /dev/stderr > login_greeting = IMAP service for edm-inc.com clients. > mail_location = maildir:~/Maildir > mail_plugins = " listescape acl" > namespace { > inbox = yes > location = > prefix = > separator = $ > type = private > } > namespace { > location = maildir:/home/vpopmail/domains/edm-inc.com/public > prefix = Jobs$ > separator = $ > subscriptions = no > type = public > } > passdb { > args = cache_key=%u%s > driver = vpopmail > } > plugin { > acl = vfile:/usr/local/etc/dovecot/acls:cache_secs=300 > } > protocols = imap > service auth { > user = root > vsz_limit = 64 M > } > service imap-login { > process_limit = 150 > service_count = 1 > } > ssl_cert = </etc/ssl/certs/mail_edm-inc_com.pem > ssl_key = # hidden, use -P to show it > userdb { > driver = vpopmail > } > userdb { > driver = vpopmail > } > protocol imap { > mail_plugins = " listescape acl imap_acl" > } -- *Bob Wooldridge* Blog: http://kc0dxf.net/blog/

Well.. updated to 2.30.1 hoping it would fix this mysterious seg fault ... ,but nope ... auth: Fatal: master: service(auth): child 14502 killed with signal 11 (core dumped) the core dump shows gdb) bt #0 0x00007f7ff4a06bee in ?? () #1 0x00007f7ff74a4f44 in io_loop_handle_remove () from /usr/local/lib/dovecot/libdovecot.so.0 #2 0x00007f7ff74a3765 in io_remove_full () from /usr/local/lib/dovecot/libdovecot.so.0 #3 0x00007f7ff7438b62 in master_service_deinit () from /usr/local/lib/dovecot/libdovecot.so.0 #4 0x00000000004307ef in main () no symbols are available as this is a pkg install.... so whats next? time to dump dovecot after running it for 10 years? Can't believe no one else is seeing this .... the symtoms are dovecot starts up fine when a client connects, they authorize just fine and download email .... about a minute later the auth process crashes and the entire process starts over .... so how do you trouble shoot this ... it sounds like a coding issue some place .... anyone ?
