Thunderbird | Attachments failed opened
by Jos Chrispijn 23 Jul '16

23 Jul '16

It lately happens that I cannot open attachments in Thunderbird45.2.0. Only when I resend the email to myself I can open it. What could be done? Found out that with Outlook there is noproblem opening these attachments. Thanks, Jos -- AI is no match for natural ignorance

Managesieve problem
by Joseph Mays 23 Jul '16

23 Jul '16

Trying to get either avelsieve or server side filters to work with managesieve. Managesieve is running but whenever avelsieve or the server settings backend try to talk to it the same thing happens. So I guess it's really a problem with something about managesieve at this point. I hit the Message Filters option, it takes a long time for it to come back, though it finally just times out and does nothing, and immediately when I click on the Message Filters link the following two messages appear in /var/log/dovecot.... 2016-07-18 17:03:02 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=108(<getpwuid() error>) egid=65534(<getgrgid() error>) missing +x perm: /, dir owned by 0:111 mode=0750) 2016-07-18 17:03:02 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=108(<getpwuid() error>) egid=65534(<getgrgid() error>) missing +x perm: /, dir owned by 0:111 mode=0750) Seems to be straightforwardly a permissions error on a directory, but I don't believe it's really the / directory, so which directory is it? Any insights on where to look would be appreciated.

Disable auth_ssl_require_client_cert for SASL
by damir 22 Jul '16

22 Jul '16

Hello! Dovecot version - 2.2.6 Postfix version - 2.10.2 OS: Mageia Linux 4 x86_64 I have configured Dovecot imaps-server on 993 port to authenticate users via private certificates: auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = no Users' database is in OpenLDAP and in dovecot-ldap.conf.ext checking of users' passwords is disabled: pass_attrs = uid=%n, mail=%n@%d, =nopassword=1 It all works fine. I have configured Postfix submission-service on 587 port to connect users via StartTLS: submission inet n - y - - smtpd -o smtpd_tls_security_level=encrypt -o smtpd_enforce_tls=yes -o smtpd_tls_req_ccert=yes -o smtpd_tls_ask_ccert=yes -o smtpd_client_restrictions=permit_tls_all_clientcerts,reject -o smtpd_recipient_restrictions=permit_tls_all_clientcerts,reject -o smtpd_helo_restrictions=permit_tls_all_clientcerts,reject It works fine. And now I have a new task: I also need Postfix to authenticate OpenLDAP-users using SASL on smtps-port 465. I need it for using on mobile devices, which don't support StartTLS. So I have configured smtps in Postfix: smtps inet n - y - - smtpd -o smtpd_tls_wrappermode=yes -o smtpd_enforce_tls=yes -o smtpd_sasl_auth_enable=yes -o smtpd_sasl_type=dovecot -o smtpd_sasl_path=private/auth -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject_unauth_destination -o smtpd_helo_restrictions=permit_sasl_authenticated,reject While trying to connect to smtps, clients get an error: "Client didn't present valid SSL certificate", and this is clear. The question is: how to configure an additional auth-service in dovecot, which doesn't require private certificates and authenticates users using login/password?

Suggested improvement for antispam plugin documentation
by Ralph Seichter 21 Jul '16

21 Jul '16

Hello, I struggled a bit with getting the antispam plugin to work, because the plugin configuration in http://wiki2.dovecot.org/Plugins/Antispam is incomplete. After some twiddling, I ended up with this: # /etc/dovecot/conf.d/90-plugin.conf plugin { antispam_backend = mailtrain antispam_mail_spam = spam antispam_mail_notspam = ham antispam_mail_sendmail = /path/to/mailtrain/script antispam_spam = Junk;Spam antispam_trash = Deleted Messages;Trash } I know that the antispam plugin has not yet been officially released, but I think it might be worth updating the documentation anyway. Your thoughts? -Ralph

an e-mail client for dovecot ?
by Spyros Tsiolis 21 Jul '16

21 Jul '16

Hello all, For some years now, I've been using Thunderbird for dovecot. I am not very satisfied with t/b so I thought of using m/s outlook but then I thought that I want to distance my clients from office products. I have a newly created dovecot installation on a very small site. Three nodes, all x86 Windows 7 professional with an ubuntu v14.04 server (x86 again) running dovecot 1.2.17. The clients there use dovecot as an imap server, so they have a real-world e-mail account each and whatever they want to keep , they store by gradding-and-dropping to the imap (local / archive) account. Since I have quite some experiece with thunderbird, I know most of its shortcomings; So I thought if there's an alternative (better?) imap mail client for x86 windows 7 systems than t/b. Even better if there's an alternative client that is also supporeted under linux . Any ideas are welcome, TIA, s.t.

Absolute path in SUBSCRIPTIONS
by Miloslav Hůla 20 Jul '16

20 Jul '16

Hello, I'm using following two namespaces with Dovecot 2.2.13-12~deb8u1: namespace inbox { inbox = yes list = yes location = prefix = INBOX. # the previous Cyrus compatibility separator = . subscriptions = yes type = private ... } namespace { inbox = no list = children location = maildir:/vmail/user/%%n/Maildir:INDEXPVT=/vmail/user/%n/Maildir/Shared/%%n prefix = user.%%n. separator = . subscriptions = yes type = shared } For the shared namespace, the subscriptions are stored globally in '/vmail/user/%%n/Maildir/subscribtions' which is bad for me. I would like too keep subscriptions per user. I cannot set 'subscriptions = no' because I have no parent namespace. And when I set :SUBSCRIPTIONS=/vmail/user/%n/Maildir/subscriptions-shared it does not work (absolute path does not work) and it creates file in: /vmail/user/%%n/Maildir/vmail/user/%n/Maildir/subscriptions-shared instead of /vmail/user/%n/Maildir/subscriptions-shared I found, that relative path hack works: :SUBSCRIPTIONS=../../%n/Maildir/subscriptions-shared but I'm not sure it is the legitimate solution. Are there other options? Kind regards, Milo

Panic when runing "doveadm mailbox status ... vsize"
by Mark Costlow 20 Jul '16

20 Jul '16

I'm using dovecot 2.2.24 on FreeBSD 10.3. I'm working on converting users from maildir to mdbox, for the usual reasons. I have converted some test users and they generally work fine. But when I run "doveadm mailbox status" I get a Panic if I ask for the vsize field (or "all"), but other fields work fine. For example: # doveadm mailbox status -u bubbacheex3 "messages" INBOX INBOX messages=53 # doveadm mailbox status -u bubbacheex3 "guid" INBOX INBOX guid=bf976912f3748957761d0100f906a3d0 # doveadm mailbox status -u bubbacheex3 "unseen" INBOX INBOX unseen=52 # doveadm mailbox status -u bubbacheex3 "vsize" INBOX doveadm(bubbacheex3): Panic: file file-lock.c: line 269: unreached Abort trap I've only converted a few users, but they all exhibit this problem. I converted them with: dsync -u bubbacheex3 mirror maildir:/var/tmp/bubbacheex3 I have done a force-resync, which succeeds but doesn't change the behavior. I spent a little time trying to get gdb running but didn't get very far (couldn't seem to get it to find the source files once I got a few levels deep in the call stack). Before I beat my head on the gdb issue more, I thought I'd check here to see if anyone has any ideas. I didn't turn up anything in google or searching this list.

Virtual mailboxes
by Lefteris Tsintjelis 19 Jul '16

19 Jul '16

I have been banging my head to the walls for the past couple of days to make virtual mailboxes work and I finally found the problem. It seems when prefetch is used the user_query is not working at all. However, I have not found any reference to this one. http://wiki.dovecot.org/Plugins/Virtual I have tried to add the SQL statements to the password_query with prefetch but it did not work. It seems that it only works with prefetch off.

dovecot --version tarball
by Leon Kyneur 19 Jul '16

19 Jul '16

Hi, Trying to understand what the version numbers mean. I typically build from the stable tarball and then apply patches as needed.. however since 2.2.25 this hasn't been working (not sure if it worked before or never really looked closely TBH). http://dovecot.org/releases/2.2/dovecot-2.2.25.tar.gz - shows GITID 7be1766 however it has commits / changes newer than this. Also the github tag for 2.2.25 is c1527e5 which doesn't match the source tarball as well. Should the source tarball and git commit hash be related? Thanks Leon
