LDAP: Connection appears to be hanging, reconnecting
by Matthias Egger 17 Dec '14

17 Dec '14

Hello List I have a strange problem here which i try to analyse, but i'm stuck. Maybe someone has a hint? What happened: A few weeks ago one of the LDAPS Servers which is not maintained by us has crashed. From that moment on, users could still login to check their emails, but they were not able to send any email through postfix (which uses smtpd_sasl_type = dovecot) What i do not understand, is why did dovecot not switch to the second configured LDAPS Server? It looks like it retried for ever to reconnect to the crashed LDAP Server. From the moment of the crash we see a lot of Errors like these in our logfiles: Nov 30 16:51:53 servername dovecot: [ID 583609 mail.error] auth: Error: ldap(userone,USERS_IP1,<WKiTeBUJQQBUSAnE>): Connection appears to be hanging, reconnecting AND Nov 30 16:51:59 servername dovecot: [ID 583609 mail.error] auth: Error: plain(usertwo,USERS_IP2,<QgJvcBUJqABTTWrJ>): Request 1982.83548 timed out after 151 secs, state=1 The used dovecot version is 2.2.13, runs on a solaris 10 system and the configuration for passdb and userdb are: passdb { args = /etc/dovecot-ldap.conf default_fields = deny = no driver = ldap master = no name = override_fields = pass = no result_failure = continue result_internalfail = continue result_success = return-ok skip = never } userdb { args = /etc/dovecot-ldap.conf default_fields = driver = ldap name = override_fields = result_failure = continue result_internalfail = continue result_success = return-ok skip = never } And the dovecot-ldap.conf contains (obfuscated): uris = ldaps://server2.tld ldaps://server1.tld ldaps://server4.tld ldaps://server3.tld dn = ... dnpass = ... ldap_version = 3 auth_bind = yes base = ... scope = onelevel user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = ... pass_attrs = uid=user pass_filter = ... The strange thing is, that with the very same binaries and configuration (okay, some minimal modifications have been made to bind to the correct interfaces...) a test on our testsystem works as it should. When we shutdown slapd, dovecot recognizes it an connects to the alternate LDAPS. When we shutdown slapd and start a netcat (just to let something listening without responding)... you guess it. Dovecot does recognize it and switches over to the alternate testsystem. So on our testsystem, everything worked as it should. But the productive system did not. And since the LDAPS are not maintained by us it is somewhat hard to try to reproduce something. At least i got the logfiles from server2.tld and server1.tld. But they only show what i still knew. Our server connected to server2.tld until the crash happened. But server1.tld never got any connection. Has someone an idea what i could try to find out why dovecot did not switch to server1.tld?

dsync summary?
by Randall Gellens 17 Dec '14

17 Dec '14

Is there a way for dsync to report a summary of what it did? For example, when finished, it could report how many messages in how many folders were added (or deleted for a two-way sync) or had flags modified, and if any messages/folders were skipped due to errors or whatever. This could provide a sanity check that a sync looks like it worked. -- Randall Gellens Opinions are personal; facts are suspect; I speak for myself only -------------- Randomly selected tag: --------------- Hippogriff: An animal (now extinct) which was half horse and half griffin. The griffin was itself a compound creature, half lion and half eagle. The hippogriff was actually, therefore, only one quarter eagle, which is two dollars and fifty cents in gold. The study of zoology is full of surprises.

Anyone know what this means and what the implications are? Does this mean some messages are missing? $sudo dsync -D -v -f -R -o mail_fsync=never backup -u test imapc: ... dsync(test): Error: imapc: Remote server didn't send BODY[] for UID 266 in #somefolder -- Randall Gellens Opinions are personal; facts are suspect; I speak for myself only -------------- Randomly selected tag: --------------- Hippogriff: An animal (now extinct) which was half horse and half griffin.

replication - more than 2 servers?
by Ron Cleven 17 Dec '14

17 Dec '14

We tested dovecot for a fair amount of time and decided finally to put it into production under CentOS 7 (we are running 2.2.10). I just joined the list, so I apologize for what is probably a question that has been answered many times, but I was wondering if there are any plans to implement replication among 3 or more servers (all "masters", as with 2)? As best as I can tell, replication seems to be limited to 2 servers, and it is not obvious to me even how more than 2 would be supported syntactically in the configs. That is, what might be an example of the "mail_replica" clauses if such a thing was supported?

Problem with TLS and Outlook 2010
by Wayne Andersen 16 Dec '14

16 Dec '14

Dovecot 2.0.9 So I am trying to get my Outlook 2010 client to use TLS with Dovecot. The Outlook error that I get is: Log onto incoming mail server (IMAP): A secure connection to the server cannot be established. I have set the port to 143,993,995 none of them work, and the security to TLS. I have all of the certificates in the full chain installed on my machine and when viewing them they all show This certificate is OK.

Dovecot lda Panic: file mail-transaction-log.c
by Alessio Cecchi 16 Dec '14

16 Dec '14

Hi, I'm running: # 2.2.15: /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.6 (3e924b1b6c5c+) # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.10 with mailbox in Maildir format and LDA to delivery new email (+ sieve for filter) on the server there is an email account that is used for "archive", it only receives messages and nobody connects to it. Today dovecot was unable to delibery, via LDA, email in the Maildir and in the log i found the following error. Login via POP or IMAP works fine but is impossibile to delivery new email (the INBOX have about 135000 emails). I have delete all files in Maildir except cur/ new/ tmp/ and rebuild the dovecot cache, but the error is the same. Could be a sieve problem?

Failed installation on Ubuntu with Postfix/Dovecot/Squirrelmail
by ghalvors78＠hushmail.com 15 Dec '14

15 Dec '14

Hello all, I did an install following a HOWTO document that has a fair number of positive reviews, but something went wrong along the way: https://www.digitalocean.com/community/tutorials/how-to-configure-a-mail-se… I made a couple deviations. I opted to not use StartSSL keys, and decided to stay with the default keys. Also, I chose to use Squirrelmail, but not Spamassassin. I tried to ensure that there are no issues with the Postfix installation (Dr. Venama and the team were quite helpful). I also had two Postfix book at my side, but I have none for Dovecot. While my goal is to get my server running, I would like to gain an understanding of Dovecot along the way, because sooner or later, it will break and I'll need to revisit the installation. First hint of a problem was that Squirrelmail would say the IMAP server dropped the connection on a successful login. So I went to a command line and used 'mail' to compose a test message from my laptop and see how the machine at Digital Ocean handled it. It didn't go over so well, in fact, it's generating errors as I'm writing this (every 5 minutes). For privacy, I swapped my domain name, for the generic example.com. Dec 14 20:24:18 example postfix/qmgr[13624]: EF3C0C0A17: from=<gary(a)Garys-MacBook-Pro.local>, size=597, nrcpt=1 (queue active) Dec 14 20:24:18 example dovecot: lmtp(21652): Connect from local Dec 14 20:24:18 example dovecot: lmtp(21652, bob(a)example.com) Error: user bob(a)example.com: Initialization failed: namespace configuration error: inbox=yes namespace missing Dec 14 20:24:18 example dovecot: lmtp(21652): Disconnect from local: Successful quit Dec 14 20:24:18 example postfix/lmtp[21651]: EF3C0C0A17: to=<bob(a)example.com>, relay=mail.example.com[private/dovecot-lmtp], delay=168169, delays=168169/0.01/0.01/0.01, dsn=4.3.0, status=deferred (host mail.example.com[private/dovecot-lmtp] said: 451 4.3.0 <bob(a)example.com> Temporary internal error (in reply to end of DATA command)) Now when I was checking that Postfix wasn't the likely problem, one of them mentioned: http://archives.neohapsis.com/archives/postfix/2014-12/0189.html (Postfix-users archive) that I needed: namespace inbox { inbox = yes } But I'm curious why that I'm the only one that seems to have been nailed by this omission. A keyword search on 'namespace' only brought up a single comment. What are your thoughts? Below, I appended the configuration files that I modified. I tried to compress them to a minimum space for the list by omitting the comments. # # /etc/dovecot/dovecot.conf # !include_try /usr/share/dovecot/protocols.d/*.protocol protocols = imap lmtp pop3 dict { } !include conf.d/*.conf !include_try local.conf # eof # # /etc/dovecot/dovecot-sql.conf.ext # driver = mysql connect = host=127.0.0.1 dbname=servermail user=usermail password=changed_it default_pass_scheme = SHA512-CRYPT password_query = SELECT email as user, password FROM virtual_users WHERE email='%u'; # eof # # /etc/dovecot/conf.d/10-auth.conf # !include auth-sql.conf.ext # eof # # /etc/dovecot/conf.d/10-mail.conf # mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = mail # eof # # /etc/dovecot/conf.d/10-master.conf # service imap-login { inet_listener imap { port = 143 } inet_listener imaps { } } service pop3-login { inet_listener pop3 { } inet_listener pop3s { } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 user = postfix group = postfix } } service imap { } service pop3 { } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 user = postfix group = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } service auth-worker { user = vmail } service dict { unix_listener dict { } } # eof # # /etc/dovecot/conf.d/10-ssl.conf # ssl=required ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem # eof Thanks for making it all the way down here!
