Problem Solr and centos 7
by HTMLServices.it 07 Aug '19

07 Aug '19

Hi everyone Given that I am not an expert, I am doing tests with Solr, I installed following the guide but I have no benefits on the search, the search on the body on 28000 mails takes a few minutes and then goes to timeout. I had installed version 8.2.0 of solr then I thought that there is something not compatible with centos 7 so I installed version 7.7.0 as an example on the guide https://wiki2.dovecot.org/Plugins/FTS/Solr. I did several tests but I can't get it to work, this is the test server link: http://5.39.2.59:8987/solr/#/ I only changed the door because the 8983 is busy even making a query from the panel it seems to me not working .... thanks to all Bic

auth-policy crashing
by James 07 Aug '19

07 Aug '19

My auth process is dumping core. This happens several times per day but dovecot can operate normally for hours between errors. The crash occurs in src/auth/auth-policy.c, line 356: t@1 (l@1) program terminated by signal SEGV (no mapping at the fault address) Current function is auth_policy_parse_response 356 context->request->policy_refusal = FALSE; ...context->request is null. Add markers to the code... } if (context->request == NULL) fprintf(stderr, "2222222222222222222222222222 context->request == NULL\n"); i_stream_unref(&context->payload); if (context->request == NULL) fprintf(stderr, "1111111111111111111111111111 context->request == NULL\n"); if (context->parse_error) { context->result = (context->set->policy_reject_on_fail ? -1 : 0); } if (context->request == NULL) fprintf(stderr, "AAAAAAAAAAAAAAAAAAAAAAAAAAAA context->request == NULL\n"); context->request->policy_refusal = FALSE; if (context->result < 0) { ...gives at the time of the crash... Aug 1 14:25:44 mailhost dovecot: [ID 702911 mail.error] auth: Error: 1111111111111111111111111111 context->request == NULL Aug 1 14:25:44 mailhost dovecot: [ID 702911 mail.error] auth: Error: AAAAAAAAAAAAAAAAAAAAAAAAAAAA context->request == NULL ...so context->result is not null before the call (no 222) to i_stream_unref but is after. dovecot.conf has: auth_policy_server_url = http://policyserver.lan/ auth_policy_server_timeout_msecs = 3000 auth_policy_hash_nonce = Ohr9phaeSeip2Pahaez2raiGohxoo5Ia auth_policy_request_attributes = remote=%{rip} auth_policy_check_before_auth = yes auth_policy_check_after_auth = yes auth_policy_report_after_auth = yes To simplify the problem I used a dummy policy server, in nginx.conf: location / { default_type application/json; return 200 "{\"status\":0,\"msg\":\"accepted\"}"; } however no matter what rubbish a policy server sends back it should not cause dovecot to crash. I've tried 32 and 64 bit and two compilers (gcc and SunStudio), all result in crashes. Adding: keepalive_timeout 0; ...to nginx.conf appears to reduce the crashes. It happens with a variety of users and with debug output I see no pattern. James.

[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. :)
