Doveadm backup issues on dovecot 2.3.1

Hello, After update dovecot from 2.3.0.1 to 2.3.1 the doveadm backup stopped to work. Command line: doveadm -D backup -u email(a)dominio.com.br -R tcp:mailsrv01:9011 I updated dovecot on mailsrv01 to 2.3.1. Process on mailsrv01 (the count message stop and process stay this way until be killed - this occurs on different mailboxs) dovecot/doveadm-server [10.0.10.5 email(a)dominio.com.br Cotacao Fornecedores export:6/86] Strace on this process: [pid 15644] epoll_wait(7, {}, 2, 4816) = 0 [pid 15644] epoll_wait(7, {}, 2, 5000) = 0 [pid 15644] close(22) = 0 [pid 15644] munmap(0x7f2927aeb000, 872) = 0 [pid 15644] close(25) = 0 [pid 15644] close(21) = 0 [pid 15644] munmap(0x7f2927aec000, 10744) = 0 [pid 15644] close(20) = 0 [pid 15644] munmap(0x7f2927ad4000, 37540) = 0 [pid 15644] close(23) = 0 [pid 15644] close(19) = 0 [pid 15644] close(11) = 0 [pid 15644] epoll_wait(7, {}, 2, 20174) = 0 Some informations: uname -a Linux mailsrv01 2.6.32-696.23.1.el6.x86_64 #1 SMP Tue Mar 13 22:44:18 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux dovecot --version 2.3.1 (c5a5c0c82) dovecot -n #

issue with sieve forwarding after upgrade to 0.5.1
by Christos Chatzaras 04 Apr '18

04 Apr '18

Hello, After I upgrade dovecot 2.2.35 to 2.3.1 and pigeonhole 0.4.23 to 0.5.1 when I use sieve to forward a message to other address using "redirect :copy" I get this: (host server1.myserver.com <http://server1.myserver.com/>[private/dovecot-lmtp] said: 451 4.2.0 <chris(a)mydomain.com <mailto:chris@mydomain.com>> Execution of Sieve filters was aborted due to temporary failure (in reply to end of DATA command)) And in sieve log I see: failed to redirect message to <chris(a)mydomain.com <mailto:chris@mydomain.com>>: Sendmail program returned error (temporary failure). Any idea what is wrong? Kind regards, Christos Chatzaras

Saving Drafts with Roundcube marks old Mails in INBOX as unread.
by sk＠tyrion.de 04 Apr '18

04 Apr '18

Hello List, I have a problem with the client Roundcube. Whenever I save a draft to the Folder INBOX.Drafts a old mail in my INBOX will be marked as unread. Here are the IMAP Logs from Roundcube and Dovecot debug logs. I have no idea why it happens. The IMAP protocol looks normal to me but as you can see in the second to last line in the Dovecot log Dovecot is changing the flag of an old E-Mail in INBOX that has the same UID as the Mail that was just created in INBOX.Drafts.

Use of separate storage for mail delivery
by SAAHIL IFTEKHAR 04 Apr '18

04 Apr '18

Hi I am facing one issue which is mostly about concepts. I have to be clear on that to move forward. I have tried finding solutions about it but couldn't find anything which talks about it. We have a setup which includes postfix and dovecot. We are using lmtp and delivery of mail is happening through dovecot. We want that delivery of mail should happen in a separate node. I was able to achieve it through lmtp by providing ip address and using port 24. But now I have been asked to just try to deliver to a separate storage medium and not node. That means it will have an ip address but no dovecot or other software running. This is in relation to incorporation of storage area network (SAN) later on. Is it possible? I thought there must be some way as many running mail systems are using message store and SAN. All i can find that was close was mailbox sharing and email archiving. Please help me about this as I have already spent 3 days to it with no luck. I just want the right direction to move forward on this. Regards

2.3.1 Replication is throwing scary errors
by Michael Grimm 03 Apr '18

03 Apr '18

Hi [This is Dovecot 2.3.1 at FreeBSD STABLE-11.1 running in two jails at distinct servers.] I did upgrade from 2.2.35 to 2.3.1 today, and I do become pounded by error messages at server1 (and vice versa at server2) as follows: | Apr 2 17:12:18 <mail.err> server1.lan dovecot: doveadm: Error: dsync(server2.lan): I/O has stalled, \ no activity for 600 seconds (last sent=mail_change, last recv=mail_change (EOL)) | Apr 2 17:12:18 <mail.err> server1.lan dovecot: doveadm: Error: Timeout during state=sync_mails \ (send=changes recv=mail_requests) […] | Apr 2 18:59:03 <mail.err> server1.lan dovecot: doveadm: Error: dsync(server2.lan): I/O has stalled, \ no activity for 600 seconds (last sent=mail, last recv=mail (EOL)) | Apr 2 18:59:03 <mail.err> server1.lan dovecot: doveadm: Error: Timeout during state=sync_mails \ (send=mails recv=recv_last_common) I cannot see in my personal account any missing replications, *but* I haven't tested this thoroughly enough. I do have customers being serviced at these productive servers, *thus* I'm back to 2.2.35 until I do understand or have learned what is going on. Any ideas/feedback? FYI: I haven't seen such errors before. Replication has been working for years now, without any glitches at all. Regards, Michael

Hi, I recently configured dovecot to manage auth for both local and virtual user. When i login as a virtual user (claudio.panetta) I get the following message: dovecot: auth: Error: passwd(claudio.panetta,160.97.62.1,<WLjlnZ9oRACgYT4B>): getpwnam() failed: Illegal seek but login is ok and sending/receiving email is ok, how can, if possible, I suppress this error message? In the following my dovecot config: host-prompt# dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-5-686-pae i686 Debian 7.11 auth_mechanisms = plain login auth_username_format = %Ln listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Server ready. mail_full_filesystem_access = yes mail_location = mbox:~/:INBOX=/var/mail/%u:INDEX=/var/index/%u mail_privileged_group = mail passdb { driver = pam } passdb { args = scheme=MD5-CRYPT username_format=%n /etc/dovecot/users driver = passwd-file } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { inet_listener imap { port = 0 } } ssl_cert = </etc/ssl/certs/chained-cert-9599-ml.mat.unical.it.pem ssl_key = </etc/ssl/private/csrkey-ml.mat.unical.it.pem userdb { driver = passwd } userdb { args = username_format=%n /etc/dovecot/users uid=vmail gid=vmail home=/var/vmail/%d/%n mail=maildir:/var/vmail/%d/%n/Maildir driver = static } verbose_proctitle = yes host-prompt# cat /etc/dovecot/users claudio.panetta:{MD5-CRYPT}$1$abcdefghijklmnopqrst ciccio.pasticcio:{MD5-CRYPT}$1$abcdefghijklmnopqrst Regards, Claudio

multi-site SSL certificates
by Jeff Abrahamson 03 Apr '18

03 Apr '18

I'm handling mail for several domains, let's call them a.com, b.com, and c.com. I have certificates for each of these domains individually via certbot (letsencrypt) and nginx is happy with all of that. Since I initially configured the site to handle mail only for a.com, my /etc/postfix/main.cf file currently has these two lines: smtpd_tls_cert_file = /etc/letsencrypt/live/mail.a.com/fullchain.pem smtpd_tls_key_file = /etc/letsencrypt/live/mail.a.com/privkey.pem But I see that mail test tools are reporting that MX for b.com and c.com are misconfigured due to an SSL name mismatch. Indeed, this is true! So I believe I should generate a multi-site SSL cert. I try this: sudo certbot certonly --cert-name postfix --webroot \ --webroot-path /var/www/a-com -d www.a.com -d a.com -d mail.a.com \ --webroot-path /var/www/b-com -d www.b.com -d b.com \ --webroot-path /var/www/c-com -d www.c.com -d c.com And that fails with a bunch of errors like this: Domain: www.a.com Type: unauthorized Detail: Invalid response from http://www.a.com/.well-known/acme-challenge/IT7-YURAep4bniD9zYpKpdRUBQcgCRJ…: "<html> <head><title>404 Not Found</title></head> <body bgcolor="white"> <center><h1>404 Not Found</h1></center> <hr><center>" I see that the file .well-known/acme-challenge/IT7-YURAep4bniD9zYpKpdRUBQcgCRJ6FflmZzWQGNg is being created (and one other file, too) but that nginx reports that the _directory_ .well-known/acme-challenge/IT7-YURAep4bniD9zYpKpdRUBQcgCRJ6FflmZzWQGNg doesn't exist. Multi-site + letsencrypt + postfix is a subject that has recently changed quite a bit, so I'm suspecting my web reading is merely leading me astray. It is also entirely possible I've misunderstood things about SSL certificates. Any pointers how to generate (or point to) the certificates that I need to make those who contact my postfix instance happy with their SSL conversation? Thanks!

dovecot lastlogin tracking

Hello, I am trying to get Dovecot 2.3.1 to track lastlogins of users. I'm using a MySQL database. When I log in I am getting this in the error log: 2018-04-02 18:24:21 imap(user(a)domain.com)<61855><6R0rDeVodcl/AAAB>: Error: last_login_dict: Failed to write value for user user(a)domain.com: dict-server returned failure: sql dict: commit failed: Field 'name' doesn't have a default value (reply took 0.026 secs (0.000 in dict wait, 0.020 in other ioloops, 0.001 in locks, async-id reply 0.000 secs ago, started on dict-server 0.019 secs ago, took 0.005 secs)) Here's an excerpt from my dovecot-dict-sql.conf.ext file: map { pattern = shared/last-login/$username table = accounts username_field = username value_field = lastlogin fields { username = $username } } I've got all users in the accounts table and there is a lastlogin column: describe accounts; +-----------+------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-----------+------------------+------+-----+---------+----------------+ | id | int(10) unsigned | NO | PRI | NULL | auto_increment | | name | varchar(255) | NO | | NULL | | | username | varchar(64) | NO | MUL | NULL | | | domain | varchar(255) | NO | MUL | NULL | | | password | varchar(255) | NO | | NULL | | | quota | int(10) unsigned | YES | | 0 | | | enabled | tinyint(1) | YES | | 0 | | | sendonly | tinyint(1) | YES | | 0 | | | lastlogin | int(11) unsigned | NO | | 0 | | Thanks.
