dovecot/lmtp dumps core when proxying to multiple recipients via protocol=smtp
by Piper Andreas 19 Feb '19

19 Feb '19

Hello, when trying to set up a migration scenario from my old mailbox-servers to my new dovecot-cluster, I get a coredump from dovecot/lmtp when proxying mail-delivery to more than one recipient on the old mailbox-server. My setup: 3 director-hosts (Debian stretch) are proxying to a pair of replicator-hosts and during migration also to the old mailbox-server. For migration the not-migrated user-addresses are included via a passwd-file with entries like: grtest1@hrz.uni-marburg.de:::::::director_tag=hrz protocol=smtp user=grtest1 grtest2@hrz.uni-marburg.de:::::::director_tag=hrz protocol=smtp user=grtest2 ... The director_tag points to the old mailbox-server, with 'protocol=smtp' SMTP is used for delivery, as the old machine is not capable of LMTP. The setup works fine for imap-proxying and for mail-delivery to single recipients. But if a mail is addressed to more than one recipient, lmtp produces a coredump after delivering to all recipients. The error-message in the log is: Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): Connect from 127.0.0.1 Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): 206UIrlNZVyX/AAAGwthQA: Sent message to <grtest2> at 137.248.xxx.yyy:25: 250 2.0.0 x1EBF5Ro016092 Message accepted for delivery (1/2 at 79 ms) Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): 206UIrlNZVyX/AAAGwthQA: Sent message to <grtest2> at 137.248.xxx.yyy:25: 250 2.0.0 x1EBF5Ro016092 Message accepted for delivery (2/2 at 79 ms) Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): Fatal: master: service(lmtp): child 64663 killed with signal 11 (core dumped) The backtrace from the coredump is: Reading symbols from /usr/lib/dovecot/lmtp...(no debugging symbols found)...done.

Migrate mail data from Dovecot to Dovecot
by Odhiambo Washington 19 Feb '19

19 Feb '19

I have built a new server (FreeBSD-12) running dovecot-2.3.4. My old server (FreeBSD-9.3) is running dovecot-2.3.4 as well. The configurations are 1:1 identical. The are about 250 users on this server, all virtual. They are mostly POP3 users, but they do "leave a copy of message on the server" for set various number of days. Now, to migrate the mail data, can I simply rsync the mail directories between the old and the new server? Would that create a pitfall?? What is the recommended method? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", grep ^[^#] :-)

Error configuring unix_listener stats-writer
by Peter Nabbefeld 18 Feb '19

18 Feb '19

Hello, I've got a very strange problem: When I try to configure the stats-writer socket, I'm told the configuration is a duplicate, though none exists in the configuration files. So I'd guess the configuration is set either built-in or implicitly. I've put the following into conf.d/10-master.conf: service auth { unix_listener auth-userdb { } unix_listener stats-writer { user = vmail group = vmail mode = 0666 } } BTW, using imap for mail traffic. Is there any tool displaying an "effective" config tree (i.e., a tool displaying the resulting configuration from every file, displaying the original file and line number)? "dovecot -a" only displays all configurations, but without source reference, so it's impossible to find out about the details. :-( Kind regards Peter

Dsync and network issues
by Danilo G. Baio 18 Feb '19

18 Feb '19

Hi. Our scenario: dovecot-2.3.4.1 Two FreeBSD servers, A (master) and B (slave). replication_max_conns = 10 doveadm_port = 60025 All mails are received on server A and replicated to server B. Sometimes we get these messages on server B: Feb 18 08:27:35 dsync-server(XX@XX): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer Feb 18 08:28:00 dsync-server(XZ@XZ): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer Feb 18 08:33:14 dsync-server(XY@XY): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer Feb 18 08:44:07 dsync-server(XW@XW): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer It happens sometimes (usually early morning) when users are syncing their mailboxes. Is there a way to debug this and find what is happening? Thanks for your time. -- Danilo G. Baio

That really depends on your dovecot config, but try doveadm log find also you can list recent errors with doveadm log errors Aki > On 17 February 2019 at 20:03 Latin Bishop <soydepr(a)gmail.com> wrote: > > > Where I find dovecot log > > > > > On Feb 17, 2019, at 12:56 PM, Aki Tuomi <aki.tuomi(a)open-xchange.com> wrote: > > > > Yes, well, this is postfix log, which is not very useful when debugging dovecot problems... > > > > Aki > > > >> On 17 February 2019 at 19:50 Latin Bishop <soydepr(a)gmail.com> wrote: > >> > >> > >> Feb 17 12:48:00 pepino postfix/smtps/smtpd[3988]: connect from localhost[127.0.0.1] > >> Feb 17 12:48:01 pepino postfix/smtps/smtpd[3988]: warning: unknown smtpd restriction: "permit_ssl_authenticated" > >> Feb 17 12:48:01 pepino postfix/smtps/smtpd[3988]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 451 4.3.5 Server configuration error; from=<pi(a)torombolo.ml> to=<pi(a)torombolo.ml> proto=ESMTP helo=<[127.0.0.1]> > >> Feb 17 12:48:07 pepino postfix/cleanup[3998]: 25EC480E6B: message-id=<20190217174807.25EC480E6B@pepino> > >> Feb 17 12:48:07 pepino postfix/smtps/smtpd[3988]: disconnect from localhost[127.0.0.1] ehlo=1 auth=1 mail=1 rcpt=0/1 quit=1 commands=4/5 > >> Feb 17 12:48:07 pepino postfix/qmgr[2604]: 25EC480E6B: from=<double-bounce@pepino>, size=970, nrcpt=1 (queue active) > >> Feb 17 12:48:07 pepino postfix/local[3999]: 25EC480E6B: to=<root(a)despiertapr.com>, orig_to=<postmaster>, relay=local, delay=0.06, delays=0.03/0/0/0.03, dsn=2.0.0, status=sent (delivered to maildir) > >> Feb 17 12:48:07 pepino postfix/qmgr[2604]: 25EC480E6B: removed > >> > >>> On Feb 17, 2019, at 12:40 PM, Aki Tuomi <aki.tuomi(a)open-xchange.com> wrote: > >>> > >>> Can you try adding 'pi' to group 'mail' too?

Re: [grosjo/fts-xapian] `doveadm fts rescan` removes all indices (#15)

A better API would be if backend simply had a way to iterate all mails in the index, preferrably sorted by folder. Then a more generic code could go through them and expunge the necessary mails and index the missing mails. Although not all FTS backends support indexing in the middle.
