logging TLS SNI hostname
by Arkadiusz Miśkiewicz 08 Nov '16

08 Nov '16

Is there a way to log SNI hostname used in TLS session? Info is there in SSL_CTX_set_tlsext_servername_callback, dovecot copies it to ssl_io->host. Unfortunately I don't see it expanded to any variables ( http://wiki.dovecot.org/Variables ). Please consider this to be a feature request. The goal is to be able to see which hostname client used like: May 30 08:21:19 xxx dovecot: pop3-login: Login: user=<abc>, method=PLAIN, rip=1.1.1.1, lip=2.2.2.2, mpid=17135, TLS, SNI=pop3.somehost.org, session=<hfS9Qwk03sBTBnrN> -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

build failure --without-ssl
by Eray Aslan 08 Nov '16

dovecot-2.2.26.0: $ ./configure --without-ssl && make [...] libtool: error: cannot find the library '../lib-ssl-iostream/libssl_iostream_openssl.la' or unhandled argument '../lib-ssl-iostream/libssl_iostream_openssl.la' make[3]: *** [Makefile:738: test-http-client] Error 1 Had a quick look. When configured without ssl, the tests were failing at run time for dovecot-2.2.25. So, this change is good but not enough. Apparently, some people do use dovecot without ssl. https://bugs.gentoo.org/show_bug.cgi?id=599024 -- Eray

Dovecot and zlib
by Peter Fraser 07 Nov '16

07 Nov '16

HI All I have a dovecot 1 server up and running without zlib and I am setting up a new Dovecot 2 Server and I want to use zlib. What is the proper way to do this? Should I set up the new server, copy the mail across and then enable zlib or do I compress the current mail in place and then copy across? Thanks for any help.

sieve sending vacation message from vmail@ns1.domain.tld
by Matthew Broadhead 07 Nov '16

07 Nov '16

I have a server running centos-release-7-2.1511.el7.centos.2.10.x86_64 with dovecot version 2.2.10. I am also using roundcube for webmail. when a vacation filter (reply with message) is created in roundcube it adds a rule to managesieve.sieve in the user's mailbox. everything works fine except the reply comes from vmail(a)ns1.domain.tld instead of user(a)domain.tld. ns1.domain.tld is the fully qualified name of the server. it used to work fine on my old CentOS 6 server so I am not sure what has changed. Can anyone point me in the direction of where I can configure this behaviour?

Errors with count:User quota and NFS
by Tom Sommer 04 Nov '16

I upgraded to 2.2.26.0 and enabled count as quota backend, expecting the recent fixes to allow me to use the backend, however I get the following errors: Oct 31 10:52:13 imap(xxxx(a)xxxx.xx): Error: Transaction log file /mnt/nfs/xxxx.xx/xxx/indexes/dovecot.list.index.log: marked corrupted Oct 31 10:52:15 imap(xxx(a)xxxx.xx): Error: Transaction log file /mnt/nfs/xxxx.xx/xxx/indexes/dovecot.list.index.log: marked corrupted Oct 31 10:52:37 imap(xxx(a)xxxx.xx): Warning: Locking transaction log file /mnt/nfs/xxx.xx/xxx/indexes/dovecot.list.index.log took 31 seconds (syncing) Oct 31 10:52:37 imap(xxx(a)xxx.xx): Warning: Locking transaction log file /mnt/nfs/xxx.xx/xxx/indexes/dovecot.list.index.log took 31 seconds (syncing) Oct 31 10:52:43 imap(xxx(a)xxx.xx): Error: Transaction log file /mnt/nfs/xxx.xx/xx/indexes/dovecot.list.index.log: marked corrupted Oct 31 10:52:52 imap(xxx(a)xxx.xx): Warning: Locking transaction log file /mnt/nfs/xxx.xx/xxx/indexes/dovecot.list.index.log took 31 seconds (syncing) Oct 31 10:53:04 imap(xxx(a)xxx.x): Warning: Locking transaction log file /mnt/nfs/xxx.xx/xxx/indexes/dovecot.list.index.log took 60 seconds (syncing) Oct 31 10:53:06 imap(xxx(a)xxx.xx): Warning: Locking transaction log file /mnt/nfs/xxx.xxx/xxx/indexes/dovecot.list.index.log took 31 seconds (syncing) (all different accounts) If I disable count as backend, there are no errors. I'm running my mail-storage on NFS, so I suspect the errors are due to locking? So is there no way to run count as quota backend with NFS? Thanks. -- Tom

deleting indices
by cheese＠nosuchhost.net 04 Nov '16

04 Nov '16

hi i have dovecot 2.0.9 - the version from rhel6 - and the following setup: two imap-servers with distinct /var/indices. those directory is local only, no sharing. the users mailboxes life on a shared nfs-storage. the two servers are setup active/passive: only one server is active and in case of a problem or maintenance the second server jumps in. no director in place. we would like to upgrade to rhel7 and add a director. there would be dovecot 2.2.10, but will take some time. one application (horde + activesync which use imap to access emails) seems to have troubles during the second server being active. horde relies according to their deveolpers heavily on modseq/qresync and if we switch to the seconds side there is another set of index-files. my knowledge was that deletion/corruption of index-files would be never a problem, as dovecot recreates them automatically. is this true for QRESNC, too? * is it a problem to have a old set of index-files on the second server, as this system is only in use every 3-4 weeks? * would it be better to start with empty indices? but there we have trouble with horde. and as it seems only with horde. "normal" imap-clients seem to be fine. yours josef

Forcibly terminated after 10 milliseconds
