Hello, I'm trying to compile the sieve plugin for dovecot2 Dovecot2-beta6 is allready running and working. i did a hg clone http://hg.renamie-it.nl/dovecot-2.0-pigeonhole and ran the autogen.sh script as mentioned in the INSTALL file configure options: /configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc --with-dovecot=/usr/lib/dovecot/ --with-managesieve=no compiling gives an error after a while: /bin/bash ../../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I../.. -I/usr/include/dovecot -DMODULEDIR=\""/usr/lib/dovecot"\" -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wstrict-aliasing=2 -MT sieve-actions.lo -MD -MP -MF .deps/sieve-actions.Tpo -c -o sieve-actions.lo sieve-actions.c libtool: compile: gcc -DHAVE_CONFIG_H -I. -I../.. -I/usr/include/dovecot -DMODULEDIR=\"/usr/lib/dovecot\" -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wstrict-aliasing=2 -MT sieve-actions.lo -MD -MP -MF deps/sieve-actions.Tpo -c sieve-actions.c -fPIC -DPIC -o .libs/sieve-actions.o sieve-actions.c: In function 'act_store_mailbox_open': sieve-actions.c:338: error: storage size of 'save_ctx' isn't known sieve-actions.c:355: warning: implicit declaration of function 'mail_deliver_save_open' sieve-actions.c:338: warning: unused variable 'save_ctx' make[4]: *** [sieve-actions.lo] Fehler 1 make[4]: Leaving directory `/usr/src/dovecot/dovecot-2.0-pigeonhole/src/lib-sieve' make[3]: *** [all-recursive] Fehler 1 make[3]: Leaving directory `/usr/src/dovecot/dovecot-2.0-pigeonhole/src/lib-sieve' make[2]: *** [all-recursive] Fehler 1 make[2]: Leaving directory `/usr/src/dovecot/dovecot-2.0-pigeonhole/src' make[1]: *** [all-recursive] Fehler 1 make[1]: Leaving directory `/usr/src/dovecot/dovecot-2.0-pigeonhole' make: *** [all] Fehler 2 am i missing something? further information can be provided. dovecot2 was configured with prefix/sysconfdir/localstatedir as above it doesnt make any differences if i change --with-dovecot to the local sources directory thanks in advance Christian Kivalo

[Dovecot] Dovecot-2.0 conf misc questions
by Thomas Hummel 29 Jun '10

29 Jun '10

Hello, I'm setting up a dovecot-2.0.beta6 install and I'm experiencing the following issues/questions : 1. Converting the config file # /usr/local/dovecot-2/bin/doveconf -n -c /usr/local/dovecot-1.2.12/etc/dovecot.conf : [...] doveconf: Fatal: Error in configuration file /usr/local/dovecot-1.2.12/etc/dovecot.conf line 176: Unknown setting: process_limit but # grep -i process_limit /usr/local/dovecot-1.2.12/etc/dovecot.conf # Well, it doesn't bother me much since I made the dovecot-2 conf from scratch anyway. 2. Changing the process limit In 10-master.conf, I changed 'service imap''s 'process_limit' from 1024 to 4096 which caused : Warning: service auth { client_limit=4096 } is lower than required under max. load (5320) Where does the 5320 come from ? 3. The = <file syntax Is there anything to know about this new syntax other than files are introduced by "<" ? 4. The "filter" hierarchy My understanding is that protocol, remote, local must be specified in the following order protocol name { remote <ip|name> { local <ip|name> { and that for a match in several blocks, the more specific wins. but it's not clear to me where they are valid and if we can negate (with a ! for instance) an argument. For instance, I want to implement the typical case of "let clients from the inside network perform a plain auth over a clear connection, require SSL before auth for the outside network clients". For that, I want to put remote <internal network address> { disable_plaintext_auth = no } in 10-auth.conf and let the 'disable_plaintext_auth = yes' in dovecot.conf But : . why is this default not in 10-auth.conf file ? . would I have been allowed to do, for instance, in that file at the same line protocol imap { remote <internal network address> { disable_plaintext_auth = no } ? . would I have been allowed to do, for instance, in that file at the same line protocol ! imap ... or remote ! <some address> ? Besides, if I set ssl=required, do I still need disable_plaintext_auth = yes ? 4. auth unix listner Default is the unix socket 'auth-userdb'. Which processes communicate through this one ? Does that mean the the auth process is not the process which performs the actual passdb/userdb lookup ? In that case what is the 'userdb process' ? Same question : what is the auth-client socket used for ? Finally, would it make sense to declare other auth listeners than the two listed by default in the 10-master.conf file ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Dovecot dies, maybe ntpdate related. I'm new to dovecot
by Xavi Montero 28 Jun '10

28 Jun '10

Hi all, my first post. After years with an old server, a couple of months ago I've installed a new one. We use IMAP. After research, I chosed dovecot. It has been running for several weeks but from one week ago or so, it suddently dies about once per day. The only change done in the server one week ago has been to install ntpdate, running once per day in cron-daily. In the cron reports, ntpdate reports a time-jump of 9 seconds each night. We did this because "apparently" we did not a "soft time drift" installing the full ntp daemon, but I start thinking the time-jump crashes dovecot. QUESTIONS: - Might this time-jump cause dovecot to die? - I don't know wehere the dovecot logs are written to. Where do I start searching? Thanks to all!

[Dovecot] "forgot my password" feature
by Mustafa Cagatayli 28 Jun '10

28 Jun '10

Hi, We have a mail server with the postfix/Squirrelmail/Dovecot(v.1.1.11) combination which we have user data on MySQL as virtual users. We have configured the SquirrelMail interface so that users can now change their own passwords. Is there any opensource solution to provide "self service password management" which would allow us to add the "I forgot my password. Lets reset it" feature which would do the authentication with the help of some random personal data or personal question/answer combination ? Regards. -- Mustafa Çağataylı BİM

Others on this list would be more help than me regarding this. From the looks of it though (after browsing the dovecot.conf file, which is well documented btw) I don't think you'd need to change a thing. We'll certainly find out if that's the case or not. I'd just give it a go. Perhaps on a test account initially. ;) -- -Eric 'shubes'
