Solr FTS - when does indexing happen?
by Shawn Heisey 06 Sep '21

06 Sep '21

I have Solr FTS on my dovecot install. I followed the instructions on the dovecot wiki. How long a delay should I expect to see between new mail being delivered with the dovecot LDA and an indexing request sent to Solr? Because I get a LOT of email from various mailing lists, and I do not see any activity in Solr's log. When I did doveadm index -A -q '*' there was a lot of indexing activity in Solr's log, as expected. One time I looked at the Solr index and it had been 23 hours since it's last update ... I can guarantee that I received a lot of new messages in that time. What do I need to look at for further troubleshooting? I can confirm that when I issue a search in the TypeApp app on my phone (an IMAP app for android), I see the query in Solr's logfile. Thanks, Shawn

100 MB RAM per clinet in an imap-proxy setup ...
by Tobias Oetiker 03 Sep '21

03 Sep '21

Hi All, I spent some quality time yesterday, tuning dovecot on a server which serves as an imap-proxy in front of a zimbra setup the imap proxy does ldap client-cert authentication and works well. BUT I found that the imap-login processes seem to gain 100 MB per connection they are accepting ... this seems pretty hefty. It does not seem to be a leak, since the setup is stable when client_limit and process_limit are set appropriately. Any ideas what part of the code I should be looking at ? Or is this a configuration problem ? cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland www.oetiker.ch tobi(a)oetiker.ch +41 62 775 9902

Using a DICT PROXY with SQL for AUTH
by dovecot＠ptld.com 02 Sep '21

02 Sep '21

https://doc.dovecot.org/configuration_manual/dict/#dict-sql https://doc.dovecot.org/configuration_manual/dict/#dict-proxy https://doc.dovecot.org/configuration_manual/dict/proxy/ I can't get the complete picture from these pages how to implement proxy with sql. I have direct sql setup now, how do i use this with proxy? passdb { driver = sql args = /etc/dovecot/mysql_login } userdb { driver = prefetch } /etc/dovecot/mysql_login: driver = mysql connect = host=/var/lib/mysql/mysql.sock dbname=redacted user=redacted password=redacted default_pass_scheme = redacted password_query = SELECT ... I feel like there is a disconnect. It says how to make a proxy service with service dict{} and it says put a dict name but where? And how do i connect my password_query to a dict? Or can you not use the proxy service for auth service? "The <destination dict> contains the dict name in the dict { .. } settings" service dict(1) { unix_listener dict(2) { mode = 0600 user = vmail } } What is the dict name, the first dict(1) or the second dict(2) or neither? Can you change "dict" in the service or unix_listner or does it always have to be "dict"? Can you use dict-async with sql?

Over Quota Reply Codes
by dovecot＠ptld.com 02 Sep '21

02 Sep '21

Dovecot quota plugin returns code 554 5.2.2 when a user inbox is full. Why 554 (transaction failed) instead of 552 (exceeded storage allocation)? Im curious behind the logic as im trying to determine the best code to use to reject a user sending more emails than their number-of-emails-limit quota. If anyone has an option to share on the best code to return it would be appreciated; 550 (policy reasons) 552 (exceeded ... allocation) 554 (transaction failed) 5.2.2 (mailbox full) 5.5.3 (Too many recipients) 5.7.0 (Other security related) 5.7.1 (delivery not authorized) Which fits best?

maildirfolder file created in maildir root during auto-creation with 2.3.4.1 but not 2.2.27
by Christian Balzer 02 Sep '21

02 Sep '21

Hello, as the tin says. I have several servers running 2.2.27 (Debian stretch) and am adding new ones with 2.3.4.1 (Debian buster). The configs were upgraded where needed but neither 10-mail.conf nor 15-mailboxes.conf were changed. 15-mailboxes is all commented out (I guess the default is auto-create, which isn't documented anywhere I could find) and the only non-comments in 10-mail.conf are --- mail_location = maildir:%h mail_privileged_group = mail --- So yes, no namespaces are explicitly defined/declared. The 2.3.4.1 version wrongly creates a maildirfolder file in the home directory (maildir root), preventing exim from correctly creating/using maildirsize. a) Is this expected behavior and can it be changed? b) How can I disable inbox auto-creation if a) doesn't pan out?

indexer crash
by Onno Molenkamp 31 Aug '21

31 Aug '21

Hi, Because I was getting segfaults in libc in calloc calls by the indexer process of Dovecot 2.3.16, I ran indexer with valgrind to look for possible memory corruption. It did indeed find that indexer was accessing memory that had already been freed, I've attached the log file. I've then tried running Dovecot with the fix in commit 97367ef61784a364ccf615cb816be6492329050d, but that didn't make any difference. Reverting (just the code in src/indexer) to the last revision before the recent rewrite to use connection.c (d76761698a06bab60a741c6794252fddec4292ef) did: valgrind doesn't log any errors anymore, and indexer has stopped crashing.
