Re: [Dovecot] ImapTest utility not compiling

* Found my error. I moved the dovecot source code after compiling it. Didn’t realize there were embedded/absolute URLS within the dovecot source tree. All I needed to do was make clean && make dovecot, then imaptest compiled no problem. [Brad Hein] From: <Hein>, Local Administrator <Brad_Hein(a)cable.comcast.com<mailto:Brad_Hein@cable.comcast.com>> Date: Wednesday, April 23, 2014 at 2:00 PM To: "dovecot(a)dovecot.org<mailto:dovecot@dovecot.org>" <dovecot(a)dovecot.org<mailto:dovecot@dovecot.org>> Subject: ImapTest utility not compiling Following the wiki instructions here: http://www.imapwiki.org/ImapTest/Installation I’ve run into a wall trying to compile the imapTest utility (dovecot compiled without any problems). I think there’s a problem in the imapTest utility? Copy/pasted compile output and attached. The gist of the problem seems to be that imaptest can’t find the dovecot headers and libraries (configure script was executed like this: ./configure --with-dovecot=/usr/src/dovecot-20140420 checkpoint.c:3:17: error: lib.h: No such file or directory checkpoint.c:4:17: error: str.h: No such file or directory <and many more> Based on these errors I believe there’s a compatibility problem between the current imapTest utility and dovecot. The configure script said to report errors to this email address. [Brad Hein]

[Dovecot] How to bring dovecot to using a slightly modified passwd file
by Stephan von Krawczynski 23 Apr '14

23 Apr '14

Hello all, I am trying to use a setup where domains have separate passwd files with a slightly different layout. Is there a way to tell dovecot that a passwd file contains everything it looks for but on different positions inside the passwd file line? Standard passwd: USERNAME:PASSWD:UID:GID:HOME:extras different layout: USERNAME:PASSWD:extras:UID:GID:HOME Or do I have to patch the source, and where if necessary? Thanks for your help. -- Regards, Stephan

[Dovecot] Allowing non-SSL connections only for certain Password Databases
by Dan Pollock 23 Apr '14

23 Apr '14

I'm trying to set up my system (using Dovecot 2.0.9) so that certain Password Databases are available over pop3 and imap and others are available over pop3s and imaps. In particular, I would like users to be able to connect without SSL to accounts set up in vpopmail, but to require SSL for system accounts. Is there a way to set "disable_plaintext_auth" to different values for different Password Databases? Is there another way to do it? Thank you, Dan

For users using system accounts, it's important that passwords are protected (as they can use that password to log in to things other than email). It's not as critical to keep virtual mailboxes on vpopmail encrypted, as those accounts only have access to email. Dan

[Dovecot] Shared mailboxes not working with . dot namespace separator - values truncated in SQL
by Frantisek Kucera 23 Apr '14

23 Apr '14

Hello, I have Dovecot configured for multiple domains (usernames are user(a)domain.tld) and I wanted to enable shared mailboxes. But there is some problem - if I share a folder, other user can't see it. In the log I foud: > Apr 22 19:21:02 veverka dovecot: imap(user(a)veverka.tld): Error: Couldn't create namespace 'shared.' for user petr: userdb didn't return a home directory, but location used it (%h): maildir:%h/Maildir:INDEX=~/Maildir/shared/%%u > Apr 22 19:21:02 veverka dovecot: imap(user(a)veverka.tld): Error: Couldn't create namespace 'shared.' for user emclient@veverka: userdb didn't return a home directory, but location used it (%h): maildir:%h/Maildir:INDEX=~/Maildir/shared/%%u Which is weird because the user name is "petr.surname" not only "petr" and the domain is "veverka.tld" not only "veverka". So I turned on SQL logging on my PostgreSQL and saw that Dovecot executes these queries: > 2014-04-22 19:21:02 CEST LOG: statement: SELECT * FROM dovecot_uzivatel WHERE login = 'petr' AND domena = '' > 2014-04-22 19:21:02 CEST LOG: statement: SELECT * FROM dovecot_uzivatel WHERE login = 'emclient' AND domena = 'veverka' The first username was "petr.surname(a)veverka.tld" and the second one was "emclient(a)veverka.tld" so it seems that it was truncated right after first "." dot and I afraid that this is a bug. Then it is obvious that Dovecot can't find the home directory and complains in log (as mentioned above). I found workaround – I had "." configured as namespace separator so I reconfigured it to "/" slash and now mailbox sharing works! But I think that it should work also with "." dot separator and the values should not be truncated in SQL queries. I tried also using '%u' in my SQL and its value was also truncated. Values in "dovecot-acl" a "shared-mailboxes" files seem to be ok. BTW: I have also another server with only one domain and simple user names (no dots) and there the mailbox sharing works – but now it seems that it works only accidentally. This might lead to hardly debuggable problems if someone has usernames with and without dots – mailbox sharing will work for some users but for some not. My old configuration: > password_query = SELECT * FROM dovecot_heslo WHERE login = '%n' AND domena = '%d' > user_query = SELECT * FROM dovecot_uzivatel WHERE login = '%n' AND domena = '%d' > iterate_query = SELECT login AS username, domena AS domain FROM dovecot_uzivatel > namespace { > type = shared > separator = . > prefix = shared.%%u. > location = maildir:%h/Maildir:INDEX=~/Maildir/shared/%%u > subscriptions = yes > list = children > } Had to be reconfigured to: > separator = / > prefix = shared/%%u/ Used version: > # dovecot --version > 2.1.7 > # uname -a > Linux veverka 3.11.0-19-generic #33-Ubuntu SMP Tue Mar 11 18:48:34 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Regards, Franta P.S. If you have similar problem and have to switch from "." to "/" separators, don't forget to update your Sieve scripts (with fileinto). And sometimes also reconfiguration of the client is needed (e.g. NGImap4ConnectionStringSeparator in SOGo; and Kontact/KMail stopped working and I had to recreate the account in this client).

[Dovecot] Can't find sieve files
by Chris Kottaridis 23 Apr '14

23 Apr '14

I have been running dovecot on a Fedora 14 host for years and am moving up to Fedora 19. I have things setup to run as a generic user vmail and have all users mailboxes in /var/vmail which is owned by the vmail user. Each user has a Maildir directory and a sieve directory. I also changed sendmail's procmail to run dovecot so it delivers into /var/vmail/<user>/Maildir instead of /var/spool/mail. I just copied the /var/vmail directory from the old machine to the new machine and made all the files there owned by vmail that had the same uid. I then compared the /etc/dovecot/conf.d files and made changes to ty and match the previous configuration as much as possible. I can send mail to a local user and se it show up in the users INBOX. However, when I watch /var/log/maillog when I send the mail I see errors like this: --------------------- script /var/vmail//ckottari/sieve/Active.sieve;name=main script (view user logfile /var/vmail//ckottari/sieve/Active.sieve.log for more information) Apr 22 17:05:46 ckottari-dhcp1 dovecot: lda(ckottari): msgid=<201404222205.s3MM5jJs003128(a)ckottari-dhcp1.wrs.com>: saved mail to INBOX --------------------- When I look at Active.sieve.log: --------------------------------------------------- sieve: info: started log at Apr 22 17:05:46. main script: line 8: error: included personal script 'My RRs.sieve' does not exist. main script: line 9: error: included personal script 'RCPL.sieve' does not exist. main script: line 10: error: included personal script 'New_Incomplete Messages.sieve' does not exist. --------------------------------------------------- Basically, I get an error message for all my scripts that get included by the Active.sieve. The Active.sieve file and all the scripts exist in the /var/vmail/<user>/sieve directory and sieve_dir is set to ~/sieve. So, I am not sure why it can't find them if it can find Active.sieve. Below is my configuration output. This has been working for years in my Fedora 14 host without errors. But, there are some configuration differences that I just kind of guessed at. Any ideas on how to get sieve working would be appreciated. $ dovecot -n # 2.2.12: /etc/dovecot/dovecot.conf # OS: Linux 3.13.5-101.fc19.x86_64 x86_64 Fedora release 19 (Schrödinger’s Cat) login_trusted_networks = 172.25.33.32/5 mail_location = maildir:~/Maildir:LAYOUT=fs 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 inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = dovecot driver = pam } plugin { sieve = ~/sieve/Active.sieve sieve_dir = ~/sieve } protocols = imap sieve ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/var/vmail/%n driver = passwd } protocol lda { mail_plugins = " sieve" } Thanks Chris Kottaridis
