[Dovecot] Thunderbird caching problem
by Chris Cappuccio 03 Sep '11

03 Sep '11

Using a fairly simple dovecot config (which obviously needs some max limit tweaking) we have problems with IMAP synchronization between thunderbird clients. Two TB clients in the same IMAP mailbox will, from time to time, show different views of the same INBOX folders, when TB caching is enabled. The only fix is to right-click on the folder, go to "Properties" and use the "Repair Folder" option which repairs the local TB .msf cache file. Is there any server-side fix/workaround that would … [View More]keep TB from regularly going out-of-sync ? This happens with TB3 and newer versions, in concert with either dovecot 1 or 2. The obvious fix is to disable TB local caching, which unfortunately also disables certain search features and can be a pain for large mailboxes. # dovecot -n # 2.0.13: /etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (7168) doveconf: Warning: service anvil { client_limit=2048 } is lower than required under max. load (3075) # OS: OpenBSD 5.0 amd64 ffs auth_default_realm = dovecot.org auth_mechanisms = plain digest-md5 cram-md5 apop auth_username_translation = :@ default_client_limit = 2048 default_internal_user = _dovecot default_login_user = _dovenull default_process_limit = 1024 disable_plaintext_auth = no first_valid_gid = 125 first_valid_uid = 125 mail_location = maildir:/mail/%d/%n/ 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 mbox_write_locks = fcntl mmap_disable = yes passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_global_path = /etc/dovecot/default.sieve } protocols = imap pop3 lmtp sieve service auth { unix_listener auth-userdb { user = mail } } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } ssl_cert = </etc/balls/balls-cert.pem ssl_key = </etc/balls/balls-key.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = sieve } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags mail_max_userip_connections = 50 } protocol pop3 { mail_max_userip_connections = 50 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_save_uidl = yes pop3_uidl_format = %v-%u } [View Less]

[Dovecot] Control of \Seen flags dovecot 1.2.9
by Kristen J. Webb 03 Sep '11

03 Sep '11

Hi All, I have public mailboxes working with ACL's now, and I'm testing the ACL behavior. I've added lrws to two users so they can check off the messages they have read. I'm using CONTROL and INDEX in the location parameter for the namespace. It appears that if one user marks a message as read, all users see that message read. Is there any way to configure dovecot, so that each user maintains their own view of read messages? Relevant config (i think): namespace private { separator =… [View More]

[Dovecot] Kerberos GSSAPI - proper item name in keytab
by Stanislav Klinkov 02 Sep '11

02 Sep '11

Hello, ALL. I am trying to organize a transparent single sign-on concept for my Active Directory users into Dovecot via IMAP. On the user's desktop I use Thunderbird 6.0 as a mail client (MUA), Windows XP as an operating system. Domain is controlled by Windows 2008 Server SP2 with Active Directory. I have installed on my Mail server Debian GNU/Linux 6.0.2 (Squeeze) and Dovecot 2.0.13 from official "wheezy" repositories of it with all dependencies. I ran into in a problem with generating … [View More]proper "/etc/krb5.keytab" file for successful kerberos authentication against AD controller. I has performed all the steps described in official dovecot wiki here: http://wiki2.dovecot.org/Authentication/Kerberos I have generated a service ticket with name "imap/efim.test.local(a)MYORG.LAN" exactly as described in wiki. ("MYORG.LAN" is my kerberos realm.) But this does not work. I see in debug logs something like this: ******** main service logs ******** Aug 29 16:05:14 auth: Info: gssapi(?,192.168.4.12): While processing incoming data: Unspecified GSS failure. Minor code may provide more information Aug 29 16:05:14 auth: Info: gssapi(?,192.168.4.12): While processing incoming data: Wrong principal in request ************************************* ******** auth debug logs ********* Aug 29 16:05:14 auth: Debug: gssapi(?,192.168.4.12): Obtaining credentials for imap(a)efim.test.local Aug 29 16:05:14 auth: Debug: client out: CONT 1 Aug 29 16:05:14 auth: Debug: client in: CONT<hidden> Aug 29 16:05:16 auth: Debug: client out: FAIL 1 ************************************* But (!). If I define << auth_gssapi_hostname = "$ALL" >> instead of << auth_gssapi_hostname = efim.test.local >> then everything works fine. I decided to find out where is the problem, so I dig into source code of gssapi module, "mech-gssapi.c". For versions 2.0.13 and 2.0.14 of dovecot I see there the following: ********* mech-gssapi.c ********* static OM_uint32 obtain_service_credentials(struct auth_request *request, gss_cred_id_t *ret_r) /* blah-blah-blah */ principal_name = t_str_new(128); str_append(principal_name, service_name); str_append_c(principal_name, '@'); str_append(principal_name, request->set->gssapi_hostname); auth_request_log_debug(request, "gssapi", "Obtaining credentials for %s", str_c(principal_name)); inbuf.length = str_len(principal_name); inbuf.value = str_c_modifiable(principal_name); major_status = gss_import_name(&minor_status, &inbuf, GSS_C_NT_HOSTBASED_SERVICE, &gss_principal); ********************************* So, according to source code, Dovecot tries to find in krb5.keytab a principal named "imap@hostname". However wiki says to create the principal named "imap/hostname@REALM". Please, clarify where is the error: in source code, in wiki, or I have misunderstood something. Respectfully, Stanislav Klinkov.

[Dovecot] OT - small hd recommendation
by Daniel L. Miller 02 Sep '11

02 Sep '11

A little OT - but I've seen a few opinions voiced here by various admins and I'd like to benefit. Currently running a single combined server for multiple operations - fileserver, mailserver, webserver, virtual server, and whatever else pops up. Current incarnation of the machine, after the last rebuild, is an AMD Opteron 4180 with a Supermicro MB using ATI SB700 chipset - which means it supports SATA 3.0. Current storage is one o/s drive, and a 4-drive RAID10 array. The RAID10 is … [View More]

[Dovecot] thunderbird and subscriptions with sieve
by Kristen J. Webb 02 Sep '11

02 Sep '11

Hi All, I'm a newbie trying to move mail out of my ISP onto a ubuntu (lucid) dovecot 1.2.9 server. Is there any way to automatically add folders created by sieve (GNU Mailutils 2.1) to the subscriptions file for a user? I'm currently testing spam, and if sieve created the folder with the first message, the thunderbird user does not see the new folder. Even more interesting, if the user then tries to create the Spam directory it thunderbird seems to quietly ignore the request and the user … [View More]
