13 Aug '19

Howdy, I'd like an adive on what to use. I have sql users, and i want to have the lastlogin of them, what is the native option for this: * Using last_login plugin which will give me the last login? * Use postlogin for imap and pop3n which will give me besides lastlogin the IP and protocol? Thanks in advanced,

[BUG?] Double quota calulation when special folder is present
by Mark Moseley 07 Aug '19

07 Aug '19

Just hoping to get some dev eyes on this. I'm incredibly reluctant to throw the word 'bug' around (since 99 times out of 100, it's not -- it's almost always the config), but I can't think of any way that this could be a config issue, esp when the pre-2.2.34 version works as expected. I noticed during troubleshooting that dovecot errors out if I try to create a subfolder called 'INBOX' but it'll happily create a subfolder called INBOX.SomethingElse (i.e. a folder called INBOX.INBOX.SomethingElse - resulting in a directory called .INBOX.SomethingElse on the filesystem, and leading to the problem described below). Is that sub-subfolder creation (where the top level subfolder matches the namespace name) supposed to be allowed? It seems odd that 'INBOX' (as a subfolder of INBOX) would be blocked but INBOX.SomethingElse (as a subfolder of INBOX) would be allowed. I'd expect INBOX.SomethingElse (i.e. INBOX.INBOX.SomethingElse) would be blocked as well.

I'm seeing the exact same after upgrading from 2.2.32 to 2.2.36. The original poster (who also narrowed it down to something in 2.2.34) mentioned a workaround that does indeed work, namely setting mailbox_list_index=no: > doveadm -o 'mailbox_list_index=no' quota recalc -u myuser I've been staring at diffs of 2.2.33 and 2.2.34 without anything jumping out at me (not a C guy, sadly). Maybe src/lib-storage/index/index-storage.c or src/lib-storage/list/mailbox-list-fs-iter.c or src/lib-storage/list/mailbox-list-index-iter.c or src/lib-storage/list/mailbox-list-index.c? The latter few have some added strcmp's against "INBOX". Then again, there's a lot of new code in the diffs under src/lib-storage that references INBOX specifically.

Dovecot replication and userdb "noreplicate".
by Reio Remma 07 Aug '19

07 Aug '19

Hello! I finally took the time and spent two days to set up replication for my server and now I have a question or two. I initially set noreplicate userdb field to 1 for all but a test user, but I could still see in the logs that all mailboxes were trying to connect to the other server via SSH. Is that normal? Jun 22 16:55:22 host dovecot: dsync-local(user(a)host.ee)<>: Error: Remote command returned error 84: ssh -i /home/vmail/.ssh/vmail.pem -l vmail backup.host.ee doveadm dsync-server -D -u user(a)host.ee Then I ended up setting mail_replica in userdb for only my test user, but I could still see in the logs that it was trying to sync the others as well, despite mail_replica being 0 for the rest. Jun 22 20:52:59 host dovecot: doveadm(user(a)host.ee): Fatal: -N parameter requires syncing with remote host I also notice (and read from recent posts) that sieve script replication doesn't work at all. Dovecot v2.3.6 and Pigeonhole from the official Dovecot CentOS repo. Thanks, Reio PS: Getting SSH for Dovecot to work with SELinux on CentOS 7 was fun as usual. :)

I am thinking they are harmless but they are generating a bunch of noise in the logs and if harmless, I would like to silence them. Can someone let me know what causes this and if I should be concerned about this? My Google foo has not been helpful on this. Regards, -- Tom me(a)tdiehl.org

GSSAPI vs group check
by Németh Ákos Ferenc 05 Aug '19

05 Aug '19

Dear All, Is it possible to make any authorization (eg. checking of group membership) in case of GSSAPI authentication? Our dovecot authenticates the users against PAM and GSSAPI. In the PAM file I'm able to check if a user is a member of a selected (e.g mailreader) group. If the user is member, he can login otherwise not (see below). If the user has a valid Kerberos ticket and he tries to login via GSSAPI, I can't restrict him if he is not a member of the selected group. How can I overcome this issue? My config: passdb { driver = pam # [session=yes] [setcred=yes] [failure_show_msg=yes] [max_requests=<n>] # [cache_key=<key>] [<service name>] #args = dovecot } userdb { # <doc/wiki/AuthDatabase.Passwd.txt> driver = passwd # [blocking=no] #args = # Override fields from passwd #override_fields = home=/home/virtual/%u } ...in PAM file: auth [success=1 default=ignore] pam_succeed_if.so user ingroup mailreader auth [success=ignore default=2] pam_succeed_if.so user ingroup admins auth [success=ignore default=1] pam_succeed_if.so uid >= 1000 auth [success=3 default=ignore] pam_winbind.so krb5_auth krb5_ccache_type=FILE cached_login auth [success=ignore default=1] pam_succeed_if.so uid < 1000 auth [success=1 default=ignore] pam_unix.so nullok_secure try_first_pass auth requisite pam_deny.so auth required pam_permit.so Thank you.

sieve scripts not synching for 2.3.5.1 pre-built
by Jan-Pieter Cornet 29 Jul '19

29 Jul '19

Hi, We're synching mailboxes, changing format from maildir to mdbox, using doveadm backup/doveadm sync. When still running 2.2.36, 'doveadm backup' also synched the sieve scripts, without issues. After the upgrade to 2.3.5.1, the sieve sync stopped working. We're using the pre-built 2.3 packages from https://repo.dovecot.org/ce-2.3-latest/debian/stretch In fact, when I now remove the dovecot-2.3 packages, and use my own old 2.2.36 packages, using the exact same config, the sieve scripts are being copied again. In 2.2.36, when I migrate a mailbox, I do see Pigeonhole being initialized. Eg: userimap-dev1:~ # doveadm -D backup -u xtra30 "doveadm -D dsync-server -u xtra30+mdbox=.8d1&4&03&xtra30" (note: that strange destination user signals to the auth proxy that we want the new mdbox storage instead of the default for this user) Debug: Loading modules from directory: /usr/lib/dovecot/modules Debug: Module loaded: /usr/lib/dovecot/modules/lib02_lazy_expunge_plugin.so Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so Debug: Module loaded: /usr/lib/dovecot/modules/lib20_zlib_plugin.so Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm Debug: Skipping module doveadm_acl_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_acl_plugin.so: undefined symbol: acl_user_module (this is usually intentional, so just ignore this message) Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_deinit (this is usually intentional, so just ignore this message) Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_quota_plugin.so Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_sieve_plugin.so [...skipping a bunch of lines...] dsync-local(xtra30): Debug: brain M: Mailbox Spam: local=88b39d12998d9e5cbb700000436edcce/0/1, remote=00000000000000000000000000000000/0/0: mailbox not selectable yet dsync-local(xtra30): Debug: brain M: Mailbox Test: local=801bb932e98d9e5c3d6d0000436edcce/0/1, remote=00000000000000000000000000000000/0/0: mailbox not selectable yet dsync-local(xtra30): Debug: brain M: Mailbox Trash: local=fc9b162b86479f5cc85a0000436edcce/0/1, remote=00000000000000000000000000000000/0/0: mailbox not selectable yet dsync-remote(xtra30): Debug: brain S: Skipping unchanged mailbox e7c1961d84479f5c885a0000436edcce dsync-local(xtra30): Debug: doveadm-sieve: Iterating Sieve mailbox attributes dsync-local(xtra30): Debug: sieve: Pigeonhole version 0.4.24 () initializing dsync-local(xtra30): Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts. dsync-local(xtra30): Debug: sieve: file storage: Using active Sieve script path: /var/mail/.8d1/index/7/oldsieve/x/xt/xtra30/dovecot.sieve [... skipping a lot of sieve debug lines that seem fine ...] dsync-remote(xtra30): Debug: sieve: file script: Opened script `xtra30-testfilter' from `/var/mail/.8d1/index/4/03/xtra30/sieve/scripts/xtra30-testfilter.sieve' dsync-remote(xtra30): Debug: doveadm-sieve: Assigned value for key `vendor/vendor.dovecot/pvt/server/sieve/default' (last change: 2019-03-29 22:27:41) dsync-remote(xtra30): Debug: brain S: Import INBOX: Import attribute vendor/vendor.dovecot/pvt/server/sieve/default: Nonexistent locally dsync-remote(xtra30): Debug: brain S: Import INBOX: Last common UID=0.

I have no idea why. We can "work around" it by explicitly doing an rsync of the sieve storage after the migration, but that's a bit of a hack.

Is it intended behavior? It seems to be caused by upgrade to 1:2.3.2-2 on Debian/Testing. -- A. Filip

submission configuration issues
by Jean-Daniel Dupas 29 Jul '19

29 Jul '19

Hello, I'm having trouble configuring the submission proxy. I have configured the submission service as follow: submission_host = smtp.example.com submission_relay_host = localhost submission_relay_port = 8587 submission_relay_rawlog_dir = /var/log/dovecot/ submission_relay_trusted = yes My main issue is that until I login, dovecot-submission won't connect to the backend and query the capabilities and so won't report the right capabilities. That mean that the first EHLO message don't get the right capabilities list. " EHLO example.com 250-smtp.example.com 250-8BITMIME 250-AUTH PLAIN LOGIN 250-BURL imap 250-CHUNKING 250-ENHANCEDSTATUSCODES 250-SIZE 250 PIPELINING " This list don't contains VRFY, DNS, and SIZE is not specified (all of these is present in backend EHLO response). After login, if I send an new EHLO command, everything is properly reported. The raw log shows that unlike what the documentation says, dovecot don't try to connect to the backend until the user is properly logged. In my raw log I show that after I logged in dovecot-submission, the later open a connection to the backend and send a X-CLIENT command. Now, if I try to force the capabilities by using: submission_backend_capabilities = VRFY 8BITMIME DSN dovecot properly reports all SMTP capabilities in the first EHLO response, but it completely stops emitting X-CLIENT command to the backend and try to simply forward the command without authentication, which result in postfix rejecting the command with an unauthorized user error. What is wrong with my configuration ? Thanks. Jean-Daniel
