doveadm who reverse dns lookups
by Michael Grant 25 Jul '18

25 Jul '18

Perhaps this is a feature request... It would be nice if the ‘doveadm who’ command printed out the reverse dns name of where the user was logged in from. Would it be possible to either add some option to doveadm who for this, or make it the do it by default and add a ‘-n’ option (like many of the other programs that look up ip addresses by default) and take a -n option to not do that? Not sure if that would break some existing thing which is why I hesitate. Might be safer to add, say, a -r option to do the rDNS lookup. However, it would definitely save me a step in figuring out where someone was logged in from to know if it’s legit. Michael Grant

I think you probably use maildir format, yes? I think my problem stems from the fact I use mbox, so one file contains many messages, whereas maildir uses one file for each message. Dovecot, from my understanding, will use the message file's mtime for date.saved if it doesn't have it in the cached. This is probably why I am seeing multiple messages with the same value. What's confusing is that if I query a message's date.saved, that value -- whether from the cache or the mailbox's mtime -- remains in the cache, so the next query will give me that value. So running "doveadm fetch ... date.saved", will get the mailbox's mtime at the time I fetched those values. In order to get near accurate date.saved values, I would have to run "doveadm fetch ... date.saved" frequently. (I think this behaviour must have changed recently because this no longer works consistently.) However, if each message is stored in a separate file (like maildir does), then each message can have an accurate date.saved(=mtime). Once you have accurate date.saved, then the "expunge savedbefore" works correctly. Another reason I really ought to switch to maildir. Joseph Tam <jtam.home(a)gmail.com>

dsync: expunge from pop3 does not replicate
by Jakub Lánský 25 Jul '18

25 Jul '18

Hi, I'm using dovecot 2.3.2.1 on Xenial from upstream packages on two Dovecot servers connected with dsync over TCP. E-mails which are deleted via POP3 protocol are not correctly deleted on second server via dsync. Jul 25 09:29:19 mda11 dovecot: pop3(jakub@***)<7587><8xaJ1c1x9uEqAB7QADwAAAAAAAAAAL7v>: expunge: box=INBOX, msgid=<6a75db5d84ff257216a4340d7c0405b2(a)blesmrt.eu>, size=3238, from=lenny@***, subject=dovecot pop3 test Nothing happened on the second machine then. After running # doveadm replicator replicate "jakub@***", e-mail got expunged immediately on second server. Jul 25 09:50:56 mda22 dovecot: dsync-local(jakub@***)<Xt6oFy8nWFsjIwAA0YRh9g>: expunge: box=INBOX, msgid=<6a75db5d84ff257216a4340d7c0405b2(a)blesmrt.eu>, size=3238, from=lenny@***, subject=dovecot pop3 test Any ideas what to do or test?

Dsync fails to connect to remote IMAP server
by Andrzej Polatyński 24 Jul '18

24 Jul '18

Hi, I'm trying to migrate from an old courier IMAP server to Dovecot 2.3.1 (8e2f634). The old server uses self signed SSL certificate. I'm using the following configuration: imapc_host = 10.1.1.3 imapc_user = %u imapc_features = rfc822.size fetch-headers imapc_port = 993 imapc_ssl = imaps imapc_ssl_verify = no mail_prefetch_count = 20 mail_shared_explicit_inbox = no Launching dsync with the command: doveadm -o mail_fsync=never -o imapc_password=PASSWORD -Dv backup -R -u USER @DOMAIN <andrzej(a)datatel.net> imapc: In the output logs I get messages like below: dsync(USER@DOMAIN): Error: imapc(10.1.1.3:993): Couldn't initialize SSL context: Can't verify remote server certs without trusted CAs (ssl_client_ca_* settings) dsync(USER@DOMAIN): Debug: imapc(10.1.1.3:993): Created new connection dsync(USER@DOMAIN): Debug: imapc(10.1.1.3:993): Looking up IP address (reconnect_ok=true, last_connect=1532016643) dsync(USER@DOMAIN): Debug: imapc(10.1.1.3:993): Connecting to 10.1.1.3:993 dsync(USER@DOMAIN): Info: imapc(10.1.1.3:993): Connected to 10.1.1.3:993 (local 172.17.0.5:51972) dsync(USER@DOMAIN): Error: imapc(10.1.1.3:993): No SSL context dsync(USER@DOMAIN): Debug: imapc(10.1.1.3:993): Disconnected Am I missing some configuration parameters? -- Regards, Andrew

dovecot sometimes sends non-default SSL cert if IMAP client won't send SNI
by Martin Johannes Dauser 24 Jul '18

24 Jul '18

Hi, I recognised some funny behaviour on my server. IMAP clients which won't send an Server Name Indication (SNI) sometimes get the wrong certificate. I would expect that those clients always get the default certificate (of my new domain), instead in about 20 to 50% of connections the certificate of my old domain will be presented. (sample rate was 3 times 30 connections) Clients sending SNI always get the right certificate. A user informed me that offlineIMAP complains 'CA Cert verifying failed: no matching domain name found in certificate' So at least offlineIMAP 7.0.12 from Debain stretch won't send SNI, there is a newer version upstream though. I myself checked the server's behaviour with openssl: $ openssl s_client -showcerts -connect IP-address:993 and $ openssl s_client -showcerts -connect IP-address:993 -servername imap.domain I'm totally clueless about how come.

Namespace question
by J Doe 24 Jul '18

24 Jul '18

Hi, I have a question about the “inbox” namespace, as mentioned in: conf.d/10-mail.conf. I have written my dovecot.conf file from scratch and do not include: conf.d/10-mail.conf. I have not defined the “inbox” namespace and so I am assuming that one is created by default. When I list the dovecot defaults via “sudo doveconf -d”, I notice that no “namespace inbox” entry exists. If “namespace inbox” is not specified, is one still created by default ? Thanks, - J

anvil in 2.3.2.1?
by kevin martin 23 Jul '18

23 Jul '18

Has anvil gone away in 2.3.2.1? I ask only because I don't find an example of anvil in the conf.d files anymore and I'm migrating from 2.2.10 version to 2.3.2.1. Thanks.
