Unfortunately I don't know how to tell any of the myriad of package installers to "do the right thing" in such cases, and, as stated, this is happening during installation. > Without seeing the full messages, my guess is that you've got problems with your IPv6 configuration or connectivity. Entirely possible, since I don't have IPv6 and have completely disabled it as a result. Even were I to re-enable it, I don't see it would help if problems with IPv6 connectivity would also be a problem (because I don't have it).

home folder for virtual users with autoexpunge setting
by felix＠kngnt.org 21 Nov '17

21 Nov '17

Hi all, I have enabled today the autoexpunge setting for Trash folders, and I am getting the following error when Dovecot starts: imap(<USER>): Error: autoexpunge: Couldn't create dovecot.autoexpunge.lock lock: User has no home directory I understand this is correct: as <USER> is a virtual user, it does not have home folder. Is there any way I can set the autoexpunge plugin to store the lock file in the virtual user email home folder? Thank you! Felix

macros in config support
by Arkadiusz Miśkiewicz 21 Nov '17

21 Nov '17

Hi. Is there any support for macros in dovecot configuration - user defined macros? For example: server-config.conf: %define my_db_name "aaa" %define my_db_host "db.example.com" %define my_db_pass "sdfdsfsdfsdf2313" %define server_id 10 %define something blabla ... dovecot-sql.conf: !include server-config.conf connect = host=%{my_db_host} dbname=%{my_db_name} .... iterate_query = SELECT ... WHERE os.id_pop3_server=%{server_id} ... Basically to be able to use own macros anywhere in config files. -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

LMTP "Relative home directory paths not supported"
by Jeff Kletsky 21 Nov '17

21 Nov '17

I'm in the process of moving from LDA to LMTP (Postfix upstream) prior to a transition off `nix accounts to virtual accounts and am stumped by LMTP reporting dovecot: lmtp(10019, jeff(a)example.com) Error: Relative home directory paths not supported: 0 LDA does /not /have any problems with PAM or passwd-file passdb/userdb and the ubiquitous definition of mail_location = maildir:~/Maildir:LAYOUT=fs I have yet to be able to get LMTP to deliver mail, nor have I found anything on the Dovecot wiki to describe how to represent that the mail_location is <whatever/userdb/returned/for/home>/Maildir I'd prefer to localize the user-to-file-space mapping localized to Dovecot (rather than split within Postfix and Dovecot) I'd definitely appreciate any pointers to web pages or specific suggestions as to how to resolve this. Excerpts of Dovecot local.conf follow, full doveconf -n output on request. The/users /file is in the same format as FreeBSD /etc/master.passwd with name, password, UID, gid, home_dir, and shell meaningfully populated. The configuration below works with LDA (end-to-end). With LMTP, it identifies <jeff(a)example.com> as a valid destination, but fails on delivery with the "relative home directory paths" error message. passdb { driver = passwd-file args = /path/to/users } userdb { driver = passwd-file args = username_format=%n /path/to/users } # See http://wiki2.dovecot.org/MailLocation/Maildir # https://wiki.dovecot.org/VirtualUsers/Home mail_location = maildir:~/Maildir:LAYOUT=fs # mail_location = maildir:%h/Maildir:LAYOUT=fs Thanks!

We are talking about a multihost installation where one host does SMTP and LDA, and the other does POP and IMAP (with dovecot). Now we want to use dovecot-lda for the local delivery _on the SMTP host_. So there is no need for open POP or IMAP ports and the corresponding running services. -- Regards, Stephan

Dovecots header files not optimized for external plugins
by Jan Engelhardt 19 Nov '17

19 Nov '17

Making third-party plugins for Dovecot is really hard and frustrating. Using dovecot 2.2.33.2 and the following sources, the compile errors keep coming. The use of g++ is mandated as the underlying backend this plugin will access only has a C++ interface. == Source 1 /* g++-7 -c a.cpp */ #include <byteswap.h> #include <dovecot/lib.h> #include <dovecot/auth-request.h> #include <dovecot/passdb.h> static enum passdb_result authdb_mapi_logon(struct auth_request *rq, const char *password) { int x = dev_null_fd + bswap_16(1); } == Problems 1 /usr/include/dovecot/compat.h:45:4: error: #error uoff_t size not set # error uoff_t size not set == Source 2 /* g++-7 -DHAVE_CONFIG_H -c a.cpp */ #include "config.h" /* generated by my configure */ #include <byteswap.h> #include <dovecot/lib.h> #include <dovecot/auth-request.h> #include <dovecot/passdb.h> static enum passdb_result authdb_mapi_logon(struct auth_request *rq, const char *password) { int x = dev_null_fd + bswap_16(1); } == Problems 2 In file included from /usr/include/bits/byteswap.h:35:0, from /usr/include/byteswap.h:24, from a.cpp:2: /usr/include/dovecot/byteorder.h:32:24: error: expected unqualified-id before ‘__extension__’ static inline uint16_t bswap_16(uint16_t in); == Other problems dovecot headers files are missing 'extern "C"' lines. This means the linkage of symbols like dev_null_fd is not what it should be. I can't use extern "C" { #include <dovecot/...> } either because then the standardy library headers that are included by dovecot headers can easily start acting up too.

user selection for replication
by Remko Lodder 18 Nov '17

18 Nov '17

Hi, I am running a setup where I have a multitude of users. Usernames are formed in both user-domain.tld and user(a)domain.tld. One to be able to login with the @ account to dovecot / webmail etc and the - account to be able to deliver email to it. Virtualmin does it like that for example. This is fine for logging in to accounts and telling postfix via lmtp which users are valid. But I do not want the - AND @ account to both synchronise. How can I select which users can replicate and then ideally like I can do in ldap ‘uid=*@*’ for example? Thanks Remko
