Hi guys, I'm running dovecot/postfix on my Debian Jessie maschine: # dovecot --version 2.2.13 doveconf -n output: http://p.bastelfreak.de/HsVwS/ today I migrated from maildir(located at /var/vmail) to mdbox with these commands: rsync -av -f"+ */" -f"- *" /var/vmail/ /home/vmail/ rm /home/vmail/*/*/Maildir -rf for i in $(doveadm user \*); do u=$(echo $i | cut -d@ -f1); d=$(echo $i |cut -d@ -f2); dsync -v -u $i mirror mdbox:/home/vmail/$d/$u/mdbox; done Then I changed the mail_location to mdbox:/home/vmail/%d/%n/mdbox and did the following commands: service dovecot restart for i in $(doveadm user \*); do u=$(echo $i | cut -d@ -f1); d=$(echo $i |cut -d@ -f2); dsync -v -u $i mirror maildir:/var/vmail/$d/$u/Mail; done doveadm index -A all INBOX for i in $(doveadm user \*); do doveadm -Dv fts rescan -u $i;done unfortunately I'm getting the following two kinds of error messages for all mail boxes in my mail.log: Error: Corrupted index cache file /home/vmail/%domain/%user/mdbox/mailboxes/%maildir/dbox-Mails/dovecot.index.cache: Broken virtual size for mail UID 2564 and: Error: read(/home/vmail/%domain/%user/mdbox/storage/m.108 ): FETCH BODY[] for mailbox %maildir UID 2564 got too little data: 2417 vs 6319 please let me know if you have any suggestions for fixing this issue or if you need more information. kind regards, Tim

dovecot & Apple Mail & maildir & lots of Mail
by Thomas Klausner 11 Dec '14

11 Dec '14

Hi! I have dovecot 2.1.12 running on a mail server, and recently configured Apple Mail to connect to it using secure IMAP, for the first time. At the beginning it just showed the inbox and everything was fine, but then I wanted to look at some of my folders and found the 'subscribe' menu. When I opened it, Apple Mail went to discover what mailboxes there are, and that's where my trouble began. It seemed to make good progress for some time (though slow -- over days), and now lists the mailboxes from starting with letters a to d on the left hand side (filling all the visible space, so there might be more). However, whenever Apple Mail gets focus, the cursor becomes a spinning rainbow circle and I can't interact with it. I tried deleting the mail account and setting it up again. The inbox was shown again immediately and Apple Mail was usable, but the first time the cursor moved over the mailboxes on the left hand side, it froze again. There were two imap processes on the server, one rather idle, the other eating CPU for about two minutes, then idling, and some time later it disappeared too. My Mail directory is 31G with about 180 directories, each containing mails in maildir format. Has anyone had similar issues? Is my maildir too big for dovecot too handle? How can I debug this? Thanks, Thomas

mail_location maildir:~/Maildir Invalid user settings[SOLVED]
by soko.tica 03 Dec '14

03 Dec '14

Hallo list, I was having quite a hard time configuring dovecot on OpenBSD -current. The problem was default Maildir setting in 10-mail.conf, namely: mail_location maildir:~/Maildir was unable to locate user's home directory. As far as I can remember, it was the correct setting on OpenBSD-current a week or two ago. Once I figured out and changed it to mail_location maildir:/path/to/home/%u/Maildir the problem was solved. Attached are dmesg, maillog and doveconf -n output.

Unknown scheme SSHA256.HEX.b64
by grundy 02 Dec '14

02 Dec '14

I'm getting a very strange error and I'm completely mystified by it. Thank you so much for taking a look! I recently migrated some users from another dovecot server to my own, and the previous admin had the passwords in their database using the SSHA256 scheme in HEX format. All the password hashes are in my database (MySQL) with a {SSHA256.HEX} prefix, and I thought at first that they were working fine, but then I checked my logs and am seeing this: localhost dovecot: auth: Error: password(***(a)***.***): Unknown scheme SSHA256.HEX.b64 (I have replaced the email address with asterisks) I am completely flabbergasted, as I can't imagine how "SSHA256.HEX.b64" is even coming in to existence as a string. I have triple checked the database and that combination appears nowhere in it. Does anybody have any idea how that is happening? Thanks again. -- View this message in context: http://dovecot.2317879.n4.nabble.com/Unknown-scheme-SSHA256-HEX-b64-tp50803… Sent from the Dovecot mailing list archive at Nabble.com.

v2.2.15 - make check - Conditional jump or move depends on uninitialised value
by AMM 01 Dec '14

01 Dec '14

Hello, I am currently using Dovecot 2.2.10 on Fedora 16 - 64 bit system I had made v2.2.10 Fedora 16 rpm file using spec file from ATrpms. http://dl.atrpms.net/all/dovecot.spec It has been working well from 6 months or so. Today I tried to make v2.2.15 rpm using same spec file. But "make check" is giving following error: fatal_printf_format_fix .............................................. : ok 0 / 190 tests failed ==8834== Conditional jump or move depends on uninitialised value(s) ==8834== at 0x4F7FE99: __strspn_sse42 (in /lib64/libc-2.14.90.so) ==8834== by 0x10FCF1: test_ds_recurse (test-data-stack.c:123) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== There are more similar errors after that and then rpmbuild aborts. I already saw that someone reported same error recently: http://dovecot.org/pipermail/dovecot/2014-October/098452.html But I do not know what is the right solution / patch? Can I disable "make check" safely? Its a production server so would not take any risk. Can anyone please tell what should I do? Thanks in advance. AMM

Unable to see virtual users
by Randall Gellens 01 Dec '14

01 Dec '14

I have a new Dovecot v2.2.9 installation and am having trouble getting virtual users recognized. Also, the example configuration listed on the Wiki generates config errors. Note that I haven't tried running dovecot yet, I wanted to verify that the config looked good first. First, my configuration. I'm trying to use /etc/dovecot/users as my combined userdb and passdb file, with all users having a UID/GID of vmail, and a home directory of /local/mnt/home/<user> ---------- $ sudo doveconf -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-39-generic x86_64 Ubuntu 14.04.1 LTS ext4 auth_verbose = yes log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mdbox:/local/mnt/mail/%n managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = username_format=%n /etc/dovecot/users driver = passwd-file } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = randy(a)qti.qualcomm.com protocols = " imap sieve pop3" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = username_format=%n /etc/dovecot/users default_fields = uid=vmail gid=vmail home=/local/mnt/home/%n driver = passwd-file } userdb { driver = passwd } ---------- Next, my /etc/dovecot/users file: $ cat /etc/dovecot/users fred:x test:{SSHA}amehbJZYxKWuIbywINVNWxKcPrWi27a+ poptest2:x poptest3:x ---------- If I ask dovecot what it knows about user 'test' it says the user doesn't exist: $ sudo doveadm user test field valueuserdb lookup: user test doesn't exist ---------- If I ask about a user in /etc/passwd, it finds it: $ sudo doveadm user nobody field value uid 65534 gid 65534 home /nonexistent mail mdbox:/local/mnt/mail/nobody system_groups_user nobody ---------- As an aside, when I copied the sample config entries from http://wiki2.dovecot.org/UserDatabase it got config errors: userdb { driver = passwd-file args = username_format=%n /etc/dovecot/users default_fields = uid=vmail gid=vmail override_fields = skip = never result_failure = continue result_internalfail = continue result_success = return-ok } The 'skip', 'result_failure', etc. entries all generated config errors as being unknown. Since these were just explicitly setting config variables to their default values, I deleted them. It does seem odd that the config sample from the Wiki generated errors though. -- Randall Gellens Opinions are personal; facts are suspect; I speak for myself only -------------- Randomly selected tag: --------------- The difference between stupidity and genius is that genius has its limits. --Albert Einstein

Working with Active Directory on Windows Server 2012 R2
by Aaron Jenkins 30 Nov '14

Hi all, I’m having issues getting Dovecot to work with AD on 2012 R2 in a test environment. Background: AD is running on dc1.ad.automaton.uk<http://dc1.ad.automaton.uk>, the domain is ad.automaton.uk<http://ad.automaton.uk>. The DNS server is running on ad.automaton.uk<http://ad.automaton.uk> and the automaton.uk<http://automaton.uk> DNS is set up correctly in the test environment in that everything resolves to the correct IP address and I can authenticate with whichever LDAP clients (ldapsearch, ApacheDS, sssd). It refuses to bind on Dovecot for some reason. aaron@mail:/var/log$ uname -a Linux mail.ad.automaton.uk 3.16.0-23-generic #31-Ubuntu SMP Tue Oct 21 17:56:17 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux aaron@mail:/var/log$ dovecot --version 2.2.9 aaron@mail:/var/log$ dpkg -l | grep dovecot ii dovecot-core 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - core files ii dovecot-gssapi 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - GSSAPI support ii dovecot-imapd 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - IMAP daemon ii dovecot-ldap 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - LDAP support aaron@mail:/var/log/$ cat dovecot-debug.log … Nov 19 09:22:23 auth: Debug: auth client connected (pid=10345) Nov 19 09:22:23 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 Nov 19 09:22:23 auth: Debug: client passdb out: CONT 1 Nov 19 09:22:23 auth: Debug: client in: CONT 1 (previous base64 data may contain sensitive data) Nov 19 09:22:29 auth: Debug: client passdb out: FAIL 1 user=aaron.jenkins temp Nov 19 09:22:29 auth: Debug: client in: AUTH 2 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 resp= (previous base64 data may contain sensitive data) Nov 19 09:22:39 auth: Debug: client passdb out: FAIL 2 user=aaron.jenkins temp Nov 19 09:22:40 auth: Debug: client in: AUTH 3 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 Nov 19 09:22:44 auth: Debug: client passdb out: CONT 3 Nov 19 09:22:44 auth: Debug: client in: CONT 3 (previous base64 data may contain sensitive data) Nov 19 09:22:50 auth: Debug: client passdb out: FAIL 3 user=aaron.jenkins temp Nov 19 09:22:50 auth: Debug: client in: AUTH 4 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 resp= (previous base64 data may contain sensitive data) Nov 19 09:22:56 auth: Debug: client passdb out: FAIL 4 user=aaron.jenkins temp (I’ve removed the base64 as it might contain passwords I actually use, if it’s important I’ll re-run it with a different password unredacted) Do you guys have any ideas on how to get it working with 2012 R2?

how to start a replication master-master correctly
by Eduardo Casarero 28 Nov '14

28 Nov '14

Hi all, I currently have one dovecot 2.2.15 working and I would like to add a second master server. If I configure the second server and enable the dsync in both servers, the sync will copy everything from A to B ? I mean, B server won't remove messages in A as it doesn't have anything in its users mailbox? The second master server will be a cold server just for contingency. Thanks
