[Dovecot] 2.0.12 Coredump under Solaris 10

hi, I've installed a testversion from 2.0.12 and getting coredumps after login via IMAP/POP3. I don't know, if it is a simple config error or something else. ====== dovecot: [ID 583609 local7.error] master: Error: service(imap): child 29333 killed with signal 11 (core dumped) [ID 583609 local7.error] master: Error: service(imap): child 29335 killed with signal 11 (core dumped) ====== my configure: CPPFLAGS="-D_POSIX_PTHREAD_SEMANTICS" LDFLAGS="-L/opt/csw/lib -L/usr/lib -R/opt/csw/lib/" ./configure --prefix=/usr/local/dovecot/2.0.12-testinstanz --with-ssl=openssl --with-rundir=/var/run/dovecot-testinstanz --with-storages=maildir,mbox,sdbox,mdbox --with-ldap=yes --sysconfdir=/usr/local/dovecot/etc-testinstanz 2.0.9 works.

Serving it temporarily from a machine in my home. I'll move it to better hosting in a few days. And I guess I should make it more fail safe some day soon.. Lets see if mailman happens to work now.

[Dovecot] calling dovecot exported auth from Java
by WJCarpenter 30 Apr '11

30 Apr '11

As far as I have been able to figure out, dovecot auth always works over a Unix domain socket. I believe it is not currently possible to operate dovecot auth over an Internet domain (TCP) socket. Am I correct? I want to call dovecot's exported authentication from a Java application. Java doesn't natively know how to talk to a Unix domain socket, so there are inconveniences. There are 3rd party JNI libraries to allow Java to do it, but I'm not too wild about the idea of using JNI. My current thinking is to rig up some kind of proxy/shuttle arrangement between a localhost TCP port and the dovecot auth Unix domain socket in the filesystem. I'm looking at using the more or less standard tool "socat" to do that. ('m on a mainstream Linux distribution.) Has anyone else confronted and solved this problem? Do tell us the details .... :-) TIA!

[Dovecot] linking problems of dovecot 2.0.3
by Funda Wang 30 Apr '11

30 Apr '11

Hello, I'm currently packaging dovecot 2.0.3 under Mandriva Linux. It has been using LDFLAGS="-Wl,--as-needed -Wl,--no-undefined" for shared libraries for over two years[1]. And I've found there are lots of linking problems with dovecot 2.0.3. After some investigation, I've made small patch regarding dovecot 2.0.3, posted here: http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/dovecot/branches… Even after applying mentioned patch, it still produce following errors: make[3]: Entering directory `/tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common' /bin/sh ../../libtool --tag=CC --mode=link gcc -std=gnu99 -O2 -g -pipe -Wformat -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4 -fstack-protector-all -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wstrict-aliasing=2 -export-dynamic -Wl,--as-needed -Wl,--no-undefined -Wl,-z,relro -Wl,-O1 -Wl,--build-id -o libdovecot-login.la -rpath /usr/lib64/dovecot liblogin.la ../lib-dict/libdict.la ../lib-dovecot/libdovecot.la -lrt libtool: link: gcc -shared -Wl,--as-needed -Wl,--whole-archive ./.libs/liblogin.a ../lib-dict/.libs/libdict.a -Wl,--no-whole-archive -Wl,--as-needed -Wl,--no-undefined -Wl,-z -Wl,relro -Wl,-O1 -Wl,--build-id -Wl,-rpath -Wl,/tmp/dovecot/BUILD/dovecot-2.0.3/src/lib-dovecot/.libs -Wl,-rpath -Wl,/usr/lib64/dovecot -L/usr/lib64/ -lssl -lcrypto -ldl -lpthread ../lib-dovecot/.libs/libdovecot.so -lrt -Wl,-soname -Wl,libdovecot-login.so.0 -o .libs/libdovecot-login.so.0.0.0 ./.libs/liblogin.a(client-common.o): In function `get_var_expand_table': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/client-common.c:372: undefined reference to `login_binary' ./.libs/liblogin.a(client-common.o): In function `client_create': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/client-common.c:50: undefined reference to `client_vfuncs' ./.libs/liblogin.a(client-common-auth.o): In function `client_auth_parse_args': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/client-common-auth.c:111: undefined reference to `login_binary' /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/client-common-auth.c:99: undefined reference to `login_binary' ./.libs/liblogin.a(client-common-auth.o): In function `client_auth_begin': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/client-common-auth.c:491: undefined reference to `login_binary' ./.libs/liblogin.a(login-settings.o): In function `login_settings_read': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/login-settings.c:195: undefined reference to `login_binary' ./.libs/liblogin.a(main.o): In function `login_access_lookup_next': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/main.c:185: undefined reference to `login_binary' ./.libs/liblogin.a(main.o):/tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/main.c:338: more undefined references to `login_binary' follow ./.libs/liblogin.a(main.o): In function `main': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/main.c:358: undefined reference to `login_process_preinit' ./.libs/liblogin.a(main.o): In function `main_init': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/main.c:308: undefined reference to `clients_init' ./.libs/liblogin.a(main.o): In function `main_deinit': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/main.c:317: undefined reference to `clients_deinit' ./.libs/liblogin.a(sasl-server.o): In function `anvil_check_too_many_connections': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/sasl-server.c:187: undefined reference to `login_binary' collect2: ld returned 1 exit status Could somebody take a look?

[Dovecot] Help a newbie...
by Juan Bernhard 29 Apr '11

29 Apr '11

Hi every one! Im new to the list, and to dovecot. I foud this program very usefull, scalable and with a serious security focus. So Im trying to implement it here at work. The first logical step is to read as much as I can, to build the best possible configuration avaible... but i found that the wiki es a pour source of serious information, filled with examples... examples are great to learn, but I was loocking for something that describes every dovecot.conf option (for example: mail_location = *string* default: mbox:~/mail:INBOX=/var/mail/%u bla,bla,bla...) Or perhaps some one can give me some directions to start reading... any help will be great. Thank you! PD: sorry for my english! haha -- ________________________________________ Juan Bernhard INSTITUTO NACIONAL DE TECNOLOGÍA INDUSTRIAL DEPARTAMENTO DE INFORMÁTICA DIVISIÓN OPERACIONES Teléfono (54 11) 4724-6200 / 6300 / 6400 Interno 6739 juan(a)inti.gob.ar _______________________________________ 0800 444 4004 | www.inti.gob.ar

[Dovecot] Dovecot Folder Creation Problem
by Ceyhun Ganioglu 29 Apr '11

29 Apr '11

Hi all, I installed Dovecot-Postfix as an IMAP mail server and also RoundCube as webmail. When I create an account using Postfix Admin and login to webmail, roundCube creates the Junk Mail, Deleted Emails folder automatically. I also added this account to my Microsoft Outlook 2007. Following some tutorials on the internet I created an Outlook rule to move the sent emails to the IMAP server's sent mail folder. When I send an email, the email disappears from the default sent items of Outlook but it doesn't appear on the IMAP server's sent items folder. Do I have to set some kind of other permissions on the IMAP server to fix this problem? My version of Dovecot is 1.2.16. I want my clients use Microsoft Outlook and reach all received and sent emails via webmail anywhere they go. Many thanks Ceyhun

[Dovecot] Problem Authenticating with Master User
by Henry Franco 29 Apr '11

29 Apr '11

Dovecot provides a master login (a master user name and password that can log into all user accounts). I've setup Dovecot as per: http://wiki1.dovecot.org/Authentication/MasterUsers Here's my problem. The only way I can authenticate successfully is if I try to authenticate through telnet twice. Also, imapsync (the tool I need to use to migrate over emails from Dovecot to other mail server) won't work because of this. $ telnet mail01.server.com 143 Trying 10.10.10.12... Connected to mail01.server.com. Escape character is '^]'. * OK Dovecot ready. 1 login user(a)server.com*master my_password 1 NO Authentication failed. 1 login user(a)server.com*master my_password 1 OK Logged in.
