user-defined special-use folders
by Fabian Schmidt 29 May '17

29 May '17

I plan to define SPECIAL-USE mailboxes and think about defining per user special-use folders for those who don't use the default folder names. Is this possible in dovecot? What I try: $ doveadm exec imap * PREAUTH [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE SEARCH=FUZZY METADATA SPECIAL-USE] Logged in as fschmidt a1 SETMETADATA "sent-mail" (/private/specialuse "\\Sent") a1 NO [CANNOT] The /private/specialuse attribute cannot be changed (0.008 + 0.000 + 0.008 secs). using dovecot 2.2.29.1, following the example in RFC 6154, sect. 5.4 (How is MAIL_ATTRIBUTE_INTERNAL_RANK_AUTHORITY defined or set?)

When will passdb callback to mechanism yield PASSDB_RESULT_NEXT?
by Peter Mogensen 29 May '17

29 May '17

Hi, code question... I've been trying to figure out the implications of the new "noauthenticate" passdb field. Internally it causes a passdb to result in PASSDB_RESULT_NEXT. When a SASL mechanism calls auth_request_lookup_credentials(...,callback) the passdb result is passed to the callback. But I can't really figure out when that result will ever be PASSDB_RESULT_NEXT. It seems the passdb fallthrough resolver will always replace it with PASSDB_RESULT_INTERNAL_FAILURE if it ends up being the last result. Can it ever leak into the callback or is it an internal intermediate value or the passdb resolver? /Peter

No doveadm-save in wiki2?

Is “doveadm save” an undocumented feature? Or, just well-hidden? https://wiki2.dovecot.org/Tools/Doveadm <https://wiki2.dovecot.org/Tools/Doveadm> Kevin

Another mail_crypt question: figure out to password secure using mysql
by dovecot＠avv.solutions 26 May '17

26 May '17

Hello Community, (sorry to be more busy, hence more running questions in parallel :) ) As mentioned in another post, I am testing mail_crypt plugin. I was wondering how to really secure the process sothat even the admin cannot have any access to the other users mail content. My current config is simple: - using per-folder keys (hence the per-user spaces are preserved) - put the public/private global keys in base64 format into the sql DB (elliptic algo) This obviously allows anyone with read access to the table to decrypt the mails from the filesystem... which I try to prevent. Considering of course that all mail users are virtual and do not (and may not) have access to the box itself: - how can I secure the keys? I do not see how to handle a assword for them? - a solution might be to crypt/decrypt the keys using the user's password? - other? Thank you for you help.

dovecot: auth-worker: Fatal: master: service(auth-worker): child XXXXX killed with signal 11
by dovecot＠jeffandjessi.com 26 May '17

26 May '17

Still Trying to track down a dovecot issue .... The error message is: dovecot: auth-worker: Fatal: master: service(auth-worker): child XXXXX killed with signal 11 (core not dumped - set service auth-worker { drop_priv_before_exec=yes }) The setup is dovecot 2.2.29.1 with passwd and mysql auth db's and a very basic config. both authentications work ... the symptom is that after a connection is made the auth worker loads and emails are downloaded and everything "is fine". However, about 30 second to a minute after the connection is done the process dies with the error message. Then the process starts all over with on the next checking of email ,but again everything "works" just seeing this error and the process dieing each time? enabled all extra verbose logging ,but nothing gives any clues.... Tried to enable core dumps ,but couldnt get core dumps to work ? The only thing is that a recently pkgsrc (netbsd) update create 2 packages, one for dovecot and one for mysql plugin , sense then now this error appears. ,but it appears the .so lib files are installed and linked correctly. Double checked all file permissions and user permissions as well as chroot , etc, etc, ,etc.... cant seem to narrow this one down .... any ideas on trouble shooting would be great .... even tried running a trace with gdb -p on the process ,but it just dies with a signal 11 .... anybody have any ideas how to trouble shoot this or is this a bug in the software .... help !!

Moving dovecot/maildir to new host, dovecot.* files
by John Gateley 26 May '17

26 May '17

Hello, I've done a fair amount of searching, and couldn't find a definitive answer. I am moving my dovecot/postfix servers and mail in Maildir formats to a new host. When I move the Maildir directories, what should I do with the dovecot.index/cache/log/etc. files? I know I can filter them out, and dovecot will recreate them, but is that the best approach? I am thinking of the following: Shut down postfix and dovecot on both the new and old server rsync the maildirs from the old server to the new server start up postfix/dovecot on the new server verify all is okay switch DNS from old server to new server. Is this the best approach with minimal impact to mail users? Thanks very much John

Public mailboxes and IPA (LDAP)
by Ranbir 26 May '17

26 May '17

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi Everyone, I have a working Dovecot server that is using my IPA domain to lookup users and passwords. I also have a "public" namespace that has the inboxes for public email accounts. Everything is working for "regular" private email boxes. But, I can't see new messages delivered to any of the public inboxes. Incoming emails get delivered to the correct locations for the public inboxes: I just don't see them in my email clients. I'm not sure what the problem is since I don't see an error in the dovecot logs. I also don't want to use the home directory location as provided by the IPA domain. I've worked around it by using file system symlinks, but I'd much rather just ignore the IPA provided home directory. I'm wondering if my workaround is the culprit behind new messages to the public folders not being seen by the client. Here's my config: # 2.2.10: /etc/dovecot/dovecot.conf auth_cache_negative_ttl = 0 auth_cache_size = 1 k auth_debug = yes auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/imap.keytab auth_mechanisms = plain gssapi auth_realms = SOME.REALM auth_username_format = %Ln auth_verbose = yes first_valid_uid = 1000 hostname = server listen = 1.1.1.1 mail_gid = virtual mail_location = maildir:~/Maildir mail_plugins = quota acl mail_uid = virtual 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 mbox_write_locks = fcntl namespace { location = maildir:/var/spool/mail/domain.tld/public prefix = Public. separator = . subscriptions = no type = public } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/conf.d/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile quota = maildir:User quota quota_rule = *:storage=500M sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster@%d protocols = imap lmtp service auth-worker { user = $default_internal_user } service auth { inet_listener { address = 1.1.1.1 port = 17900 } unix_listener auth-userdb { group = virtual mode = 0600 user = virtual } } service imap-login { process_min_avail = 2 service_count = 1 } service lmtp { inet_listener lmtp { address = 1.1.1.1 port = 24 } } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem ssl_protocols = !SSLv2 !SSLv3 userdb { args = /etc/dovecot/conf.d/dovecot-ldap-userdb.conf.ext default_fields = uid=virtual gid=virtual driver = ldap } verbose_proctitle = yes protocol lmtp { mail_plugins = quota acl sieve } protocol lda { mail_plugins = quota acl sieve } protocol imap { mail_plugins = quota acl imap_quota imap_acl } - -- Ranbir -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCgAGBQJZJz5lAAoJEN7T/ly5z1dituQQAIvq/DyDq5JbyREpopj5XcgN RjuvFAf2VuR9ieBnJ66GZPS9kcLZusqTzFyBczJmvq5sHRR8+UvRhsDVGGRNGFS+ 5b6oJNbP5BYP+93Ik8Ai7XgkaSfzIVg6cpru0uzMN0FvzQWXGONKQhMI0dFF+rFf 377gxho3AiAUxffX/vRhOvmE5/loJL9g8WDd6qAdZ6Ow3X3ISIWTo8ICWcndxWJK WU+/vsXfg1Up96M9X38FIhCBVcJG+igUXqZ3/0+N4at/L6BI5BWmG21XpaReGORo QjVaDIeFw4supnaKJszYiiYU1vQRHyvW5p2V0l1Q7mIh/sqANYhqJpziCP9yx1gN g0iv32V2EPxI44ympuhFtAslqyyGhfMtHOsufQ/QbrwjJAML/TRJYuyqh0hiZ+0h anhkDmkb0mlJlroPYJatiqJZqOYNRmtT8QpRMqapELDBo/Rc2LzqnkrgEso2XjI3 yLYXSgV1cY7HNJzhIvmPWZDncF4LW5o3JpidCdcDRnXvDUc3tyb/qRQkvI1+Zycw P5n2r+9BcSWA194TU+QPzvdB9MKQ+Cn3dM0HwYkEqQXH7BVgKKvXobaM+mOgBjLL Ais+yc0aeoKV5r3ln74HPRyXfw0Zp9g128BwzQG597kPhXaXb9Hd5o58LMkdMfxs 5ycn42U8p2ZiKHFDx9vO =swZL -----END PGP SIGNATURE-----

"@LIBICU_CFLAGS@: No such file or directory" during libtool command for lib-fts (cross compile)
by awl1 26 May '17

26 May '17

Hello, I am a complete newbie to dovecot, but do have reasonable experience in compiling Unix/Linux software. I am currently trying to do a cross-compile of dovecot-2.29.1 to be used on my home office Thecus NAS (host: Thecus kernel 2.6.33 on 32-bit Intel Atom: "i686-nptl-linux-gnu"; my build machine has Ubuntu 16.04.2 LTS) "from ground up", i.e. I need to build and provide all dovecot dependencies from within my module. My compiler toolchain (using gcc-5.2.0) has been set up properly using ct-ng and works completely fine. I also have already successfully cross-compiled/built almost all dovecot dependencies (zlib, bzip2, xz, lz4, openssl-1.0.2, clucene-git, snowball-git, libexttextcat, icu) - i.e. including icu - and installed them properly into my cross-compile build root (/raid/data/module/Dovecot/sys as defined by Thecus module spec).

So do you have any idea why variable substitution for LIBICU_CFLAGS does not work, and what could be done to work around this? Many thanks in advance for your kind help with this!
