[Dovecot] "Select Inbox" drops connection. IMAP troubleshooting help available?
by Thor Legvold 11 Dec '13

11 Dec '13

Newbie to the list here. I don’t know if this is Dovecot specific, but I can see that my IMAP server is running Dovecot. So far (as a client) I haven’t been able to figure out how to get it to tell me the version number. What I’m trying to get is more detailed info in order to debug an IMAP problem. I’ve been unable to retrieve email since the 27th of November on this specific account. Another user on the same domain/email receives and sends email just fine. Having tried both Apple Mail, Thunderbird, as well as a Telnet terminal connection, I see two problems, but am unaware of what to do from here to verify or fix the problem. First is that the SSL certificate is a self signed one from some local hosting service. Fair enough, I told OS X to trust it (for now), both in Mail and Thunderbird (and Safari). Second is that when logging in via the terminal, I can log in fine, navigate to any folder and read any email on the server - with the exception of the Inbox. Anytime I issue a “Select” or “Examine” command with the “Inbox” as argument, the connection is dropped. E.g.: after logging in, listing folders, navigating around, I do this: a select inbox closed Sonovo:~ Thunder$ and am back at the terminal prompt. If I do an “Email Trace” in CPanel on my server (hosting both my website and IMAP email accounts), I see a long list of emails accepted to my address and in the system, but I cannot seem to access them from any client. There may well be a better list/forum for discussing this kind of thing. I was actually on a mailing list years ago with Mark Crispin himself, but haven’t spoken with him in 10 years or more. I’m not sure where to go for more help/info. I’m not a complete (l)user, but nor am I a guru (tm). Any tips or help is greatly appreciated! Sonovo

[Dovecot] post-logout scripting
by Jouko Nikula 11 Dec '13

11 Dec '13

Hi all, I found this (http://www.dovecot.org/list/dovecot/2010-January/045717.html) describing how to do a post-logout script. But is this valid anymore? It seems I'm getting error when trying to execute imap process in post-logout script and post logout documentation does not talk about executing imap. I'm trying to umount (virtual) user home directory when user logs out. Thanks, - Jouko

[Dovecot] undoing a zlib test
by Terry Barnum 10 Dec '13

10 Dec '13

I'm trying to undo a dovecot zlib test and uncompress 6 emails in my Junk mailbox. There are about 25 total in different mailboxes but I thought I'd first start with those in my Junk. I ran: # dsync -v -u terry(a)dop.com -m Junk -o plugin/zlib_save= backup maildir:/path/to/temp/folder which returned without error and backed up my Junk mailbox but didn't uncompress the 6 emails. Am I calling dsync incorrectly to uncompress? zlib is currently not loaded as a plugin. Once I get them uncompressed is doveadm import the correct way to get them back into my Junk mailbox? Something like this? # doveadm -v import -u terry(a)dop.com maildir:/path/to/temp/folder "" mailbox Junk SENTON 2013-12-06 Thanks, -Terry # 2.2.9: /opt/local/etc/dovecot/dovecot.conf # OS: Darwin 11.4.2 x86_64 hfs auth_verbose = yes base_dir = /opt/local/var/run/dovecot/ default_internal_user = _dovecot default_login_user = _dovenull first_valid_uid = 102 last_valid_uid = 105 listen = * mail_gid = 102 mail_location = maildir:/Volumes/mail/vmail/%d/%u mail_uid = 102 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /opt/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { antispam_backend = dspam antispam_debug_target = syslog antispam_dspam_args = --user;%u;--deliver=;--source=error;--signature=%%s antispam_dspam_binary = /opt/local/bin/dspamc antispam_dspam_notspam = --class=innocent antispam_dspam_result_header = X-DSPAM-Result antispam_dspam_spam = --class=spam antispam_signature = X-DSPAM-Signature antispam_signature_missing = move antispam_spam_pattern_ignorecase = junk;spam;junk * antispam_trash_pattern_ignorecase = trash;deleted * mail_log_events = flag_change append delete undelete expunge copy sieve = ~/dovecot.sieve sieve_before = /Volumes/mail/vmail/%d/global/global.sieve sieve_dir = ~/sieve } protocols = imap pop3 lmtp sieve sendmail_path = /opt/local/sbin/sendmail service auth-worker { user = $default_internal_user } service auth { unix_listener /opt/local/var/spool/postfix/private/auth { group = _postfix mode = 0660 user = _postfix } unix_listener auth-userdb { mode = 0660 user = _vmail } } ssl_cert = </opt/local/etc/ssl/certs/dovecot.cert ssl_key = </opt/local/etc/ssl/private/dovecot.key userdb { args = /opt/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = " sieve" } protocol lda { mail_plugins = " sieve" postmaster_address = postmaster(a)dop.com } protocol imap { mail_max_userip_connections = 50 mail_plugins = " antispam" } Terry Barnum digital OutPost http://www.dop.com

Re: [Dovecot] Index issue? - SOLVED

They were subscribed in Outlook, but there's no option to set that on the iPad. The solution was to edit the mail account settings on the iPad and specify a root folder "INBOX" (minus quotes). -Mark On 10 December 2013 13:15, Daniel Parthey <d.parthey(a)metaways.de> wrote: > Are all the subfolders subscribed? > > For example Thunderbird doesn't show unsubscribed folders by default. > > Regards > Daniel

[Dovecot] dsync verbosity, summary of transfer
by Alan McGinlay - SICS 10 Dec '13

10 Dec '13

Hi! I am playing with dsync and trying to fix an issue I have mentioned in another thread (subject: "Re: [Dovecot] Dsync error: Couldn't drop privileges: getgrnam") and feel that dsync could use some additional informational output. It would be particularly helpful while experimenting with a migration if it could output a transfer summary and / or log separately. A summary could be similar to that which imapsync outputs after completion, for example: ++++ Statistics Transfer started on : Thu Dec 5 20:30:05 2013 Transfer ended on : Thu Dec 5 20:32:00 2013 Transfer time : 114.3 sec Messages transferred : 7 Messages skipped : 766 Messages found duplicate on host1 : 0 Messages found duplicate on host2 : 0 Messages void (noheader) on host1 : 0 Messages void (noheader) on host2 : 0 Messages deleted on host1 : 0 Messages deleted on host2 : 9 Total bytes transferred : 71820 (70.137 KiB) Total bytes duplicate host1 : 0 (0.000 KiB) Total bytes duplicate host2 : 0 (0.000 KiB) Total bytes skipped : 10070561 (9.604 MiB) Total bytes error : 0 (0.000 KiB) Message rate : 0.1 messages/s Average bandwidth rate : 0.6 KiB/s Reconnections to host1 : 0 Reconnections to host2 : 0 Memory consumption : 90.5 MiB Biggest message : 39274 bytes Detected 0 errors

[Dovecot] Dovecot+LDAP lda problem
by Zeljko Culek 10 Dec '13

10 Dec '13

Hello everyone, I need some help with Dovecot+LDAP config and local delivery. We're using Dovecot 2.0.9 on Centos 6.4. Before, we used Qmail with the same LDAP. Our LDAP accounts have the attribute deliveryMode which we used for mailing lists (OK, they are in fact mailing groups rather than lists). When the attribute is set to deliveryMode = nolocal Qmail did not deliver mail to the list mailbox, only to the accounts on the list/group. Now with Dovecot(+postfix) I can't achieve the same behaviour. Can Dovecot be set up not to deliver the mail to the list mailbox if the list has the attribute deliveryMode = nolocal? This is my /etc/dovecot/conf.d/dovecot-ldap.conf.ext hosts = xxx.xxx.xxx.xxx auth_bind = yes dn = cn=admin,dc=nth,dc=ch dnpass = xxxxxxxxxx ldap_version = 3 base = dc=nth,dc=ch #deref = always scope = subtree user_attrs = mail=user user_filter = (|(&(objectclass=inetOrgPerson)(mail=%u))(|(mailAlternateAddress=%u))) pass_attrs = uid=user pass_filter = (&(objectclass=inetOrgPerson)(|(mail=%u)(mailAlternateAddress=%u))) default_pass_scheme = CRYPT Basicaly, I want to make check: if deliveryMode=nolocal > do not deliver to mail=some.mail(a)tld.com (only to mailForwardingAddress) else deliver normally :) Thnx, -- Zeljko Culek IT Department Samurai Digital d.o.o.

[Dovecot] Index issue?
by IT geek 31 10 Dec '13

10 Dec '13

I've just hastily migrated from Dovecot 1.2.9 to 2.2.9 due to a disk crash. When I say hastily, I literally copied the user's mail data files to the new server and then started the Dovecot service. The trouble is, I now have a user who can see all the subfolders of her inbox in Outlook, but not on her iPad. Do I need to re-index her mail folders? The data is there (as seen by Outlook 2013) and is good, but the iPad mail client only sees the top-level folder. Any thoughts? -Mark

[Dovecot] Problem with INDEXes and deleting shared folders
by Achim Gottinger 10 Dec '13

10 Dec '13

Hi, I use dovecot 2.1.7 on debian wheezy. I have a bunch of shared folders whom i configured to store the indexe's under the users mail_location/shared/%%u. I configured acl's for those shared folders in an way that all users should be able to add and delete folders (for example "group=buchhaltung keilrwtsx"). Creating folders works fine but if i try to delete such an folder i get the following error. Dec 10 12:03:41 logon-zor dovecot: imap(ag): Debug: Can't rename 'shared/buchhaltung/Test' to 'Trash/Test': one namespace has index dir and another doesn't Of course there is no dovecot.index file in /home/vmail/buchhaltung/mai/.Test but there is one in /home/ag/vmail/mail/shared/buchhaltung/.Test and in /home/ag/vmail/mail/.Trash. Seems dovecot does not honour the shared namespaces index settings when trying to rename that folder. Is there an fix for this issue in 2.1.7 or would upgrade to 2.2.5 (from debian unstable) help? Thanks in advance Achim Gottinger Here are my namespace mail_location etc. settings: mail_home = /home/vmail/%u mail_location = maildir:/home/vmail/%u/mail:INDEX=/home/vmail/%u/mail:INBOX=/home/vmail/%u/mail/.INBOX mail_uid = 998 mail_gid = 998 first_valid_uid = 998 first_valid_gid = 998 mail_shared_explicit_inbox = yes maildir_very_dirty_syncs = yes namespace { list = children location = maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u:INBOX=/home/vmail/%%u/mail/.INBOX prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { inbox = yes location = maildir:/home/vmail/%u/mail:INDEX=/home/vmail/%u/mail:INBOX=/home/vmail/%u/mail/.INBOX prefix = separator = / type = private }

[Dovecot] Panic: file acl-cache.c

Hello, our dovecot mailservice was running smoothly for a long time. Since last week we get the following error message when connecting from the horde/imp webmailer to the public namespace: Panic: file acl-cache.c: line 294 (acl_cache_update): assertion failed: (obj_cache->my_current_rights != &negative_cache_entry) Dovecot and horde/imp are running on seperate hosts.
